Microsoft Excel is a spreadsheet developed by Microsoft for Windows, macOS, Android, iOS and iPadOS. It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel forms part of the Microsoft 365 suite of software.

Features

Basic operation

Microsoft Excel has the basic features of all spreadsheets,[7] using a grid of cells arranged in numbered rows and letter-named columns to organize data manipulations like arithmetic operations. It has a battery of supplied functions to answer statistical, engineering, and financial needs. In addition, it can display data as line graphs, histograms and charts, and with a very limited three-dimensional graphical display. It allows sectioning of data to view its dependencies on various factors for different perspectives (using pivot tables and the scenario manager).[8] A PivotTable is a tool for data analysis. It does this by simplifying large data sets via PivotTable fields. It has a programming aspect, Visual Basic for Applications, allowing the user to employ a wide variety of numerical methods, for example, for solving differential equations of mathematical physics,[9][10] and then reporting the results back to the spreadsheet. It also has a variety of interactive features allowing user interfaces that can completely hide the spreadsheet from the user, so the spreadsheet presents itself as a so-called application, or decision support system (DSS), via a custom-designed user interface, for example, a stock analyzer,[11] or in general, as a design tool that asks the user questions and provides answers and reports.[12][13] In a more elaborate realization, an Excel application can automatically poll external databases and measuring instruments using an update schedule,[14] analyze the results, make a Word report or PowerPoint slide show, and e-mail these presentations on a regular basis to a list of participants. Excel was not designed to be used as a database.[citation needed]

Microsoft allows for a number of optional command-line switches to control the manner in which Excel starts.[15]

Functions

Excel 2016 has 484 functions.[16] Of these, 360 existed prior to Excel 2010. Microsoft classifies these functions in 14 categories. Of the 484 current functions, 386 may be called from VBA as methods of the object «WorksheetFunction»[17] and 44 have the same names as VBA functions.[18]

With the introduction of LAMBDA, Excel will become Turing complete.[19]

Macro programming

VBA programming

Use of a user-defined function sq(x) in Microsoft Excel. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel.

Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y.

The Windows version of Excel supports programming through Microsoft’s Visual Basic for Applications (VBA), which is a dialect of Visual Basic. Programming with VBA allows spreadsheet manipulation that is awkward or impossible with standard spreadsheet techniques. Programmers may write code directly using the Visual Basic Editor (VBE), which includes a window for writing code, debugging code, and code module organization environment. The user can implement numerical methods as well as automating tasks such as formatting or data organization in VBA[20] and guide the calculation using any desired intermediate results reported back to the spreadsheet.

VBA was removed from Mac Excel 2008, as the developers did not believe that a timely release would allow porting the VBA engine natively to Mac OS X. VBA was restored in the next version, Mac Excel 2011,[21] although the build lacks support for ActiveX objects, impacting some high level developer tools.[22]

A common and easy way to generate VBA code is by using the Macro Recorder.[23] The Macro Recorder records actions of the user and generates VBA code in the form of a macro. These actions can then be repeated automatically by running the macro. The macros can also be linked to different trigger types like keyboard shortcuts, a command button or a graphic. The actions in the macro can be executed from these trigger types or from the generic toolbar options. The VBA code of the macro can also be edited in the VBE. Certain features such as loop functions and screen prompt by their own properties, and some graphical display items, cannot be recorded but must be entered into the VBA module directly by the programmer. Advanced users can employ user prompts to create an interactive program, or react to events such as sheets being loaded or changed.

Macro Recorded code may not be compatible with Excel versions. Some code that is used in Excel 2010 cannot be used in Excel 2003. Making a Macro that changes the cell colors and making changes to other aspects of cells may not be backward compatible.

VBA code interacts with the spreadsheet through the Excel Object Model,[24] a vocabulary identifying spreadsheet objects, and a set of supplied functions or methods that enable reading and writing to the spreadsheet and interaction with its users (for example, through custom toolbars or command bars and message boxes). User-created VBA subroutines execute these actions and operate like macros generated using the macro recorder, but are more flexible and efficient.

History

From its first version Excel supported end-user programming of macros (automation of repetitive tasks) and user-defined functions (extension of Excel’s built-in function library). In early versions of Excel, these programs were written in a macro language whose statements had formula syntax and resided in the cells of special-purpose macro sheets (stored with file extension .XLM in Windows.) XLM was the default macro language for Excel through Excel 4.0.[25] Beginning with version 5.0 Excel recorded macros in VBA by default but with version 5.0 XLM recording was still allowed as an option. After version 5.0 that option was discontinued. All versions of Excel, including Excel 2021 are capable of running an XLM macro, though Microsoft discourages their use.[26]

Charts

Graph made using Microsoft Excel

Excel supports charts, graphs, or histograms generated from specified groups of cells. It also supports Pivot Charts that allow for a chart to be linked directly to a Pivot table. This allows the chart to be refreshed with the Pivot Table. The generated graphic component can either be embedded within the current sheet or added as a separate object.

These displays are dynamically updated if the content of cells changes. For example, suppose that the important design requirements are displayed visually; then, in response to a user’s change in trial values for parameters, the curves describing the design change shape, and their points of intersection shift, assisting the selection of the best design.

Add-ins

Additional features are available using add-ins. Several are provided with Excel, including:

  • Analysis ToolPak: Provides data analysis tools for statistical and engineering analysis (includes analysis of variance and regression analysis)
  • Analysis ToolPak VBA: VBA functions for Analysis ToolPak
  • Euro Currency Tools: Conversion and formatting for euro currency
  • Solver Add-In: Tools for optimization and equation solving

Data storage and communication

Number of rows and columns

Versions of Excel up to 7.0 had a limitation in the size of their data sets of 16K (214 = 16384) rows. Versions 8.0 through 11.0 could handle 64K (216 = 65536) rows and 256 columns (28 as label ‘IV’). Version 12.0 onwards, including the current Version 16.x, can handle over 1M (220 = 1048576) rows, and 16384 (214, labeled as column ‘XFD’) columns.[27]

File formats

Excel Spreadsheet

Filename extension

.xls, (.xlsx, .xlsm, .xlsb — Excel 2007)

Internet media type

application/vnd.ms-excel

Uniform Type Identifier (UTI) com.microsoft.excel.xls
Developed by Microsoft
Type of format Spreadsheet

Microsoft Excel up until 2007 version used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format.[28] Excel 2007 uses Office Open XML as its primary file format, an XML-based format that followed after a previous XML-based format called «XML Spreadsheet» («XMLSS»), first introduced in Excel 2002.[29]

Although supporting and encouraging the use of new XML-based formats as replacements, Excel 2007 remained backwards-compatible with the traditional, binary formats. In addition, most versions of Microsoft Excel can read CSV, DBF, SYLK, DIF, and other legacy formats. Support for some older file formats was removed in Excel 2007.[30] The file formats were mainly from DOS-based programs.

Binary

OpenOffice.org has created documentation of the Excel format. Two epochs of the format exist: the 97-2003 OLE format, and the older stream format.[31] Microsoft has made the Excel binary format specification available to freely download.[32]

XML Spreadsheet

The XML Spreadsheet format introduced in Excel 2002[29] is a simple, XML based format missing some more advanced features like storage of VBA macros. Though the intended file extension for this format is .xml, the program also correctly handles XML files with .xls extension. This feature is widely used by third-party applications (e.g. MySQL Query Browser) to offer «export to Excel» capabilities without implementing binary file format. The following example will be correctly opened by Excel if saved either as Book1.xml or Book1.xls:

<?xml version="1.0"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:o="urn:schemas-microsoft-com:office:office"
 xmlns:x="urn:schemas-microsoft-com:office:excel"
 xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:html="http://www.w3.org/TR/REC-html40">
 <Worksheet ss:Name="Sheet1">
  <Table ss:ExpandedColumnCount="2" ss:ExpandedRowCount="2" x:FullColumns="1" x:FullRows="1">
   <Row>
    <Cell><Data ss:Type="String">Name</Data></Cell>
    <Cell><Data ss:Type="String">Example</Data></Cell>
   </Row>
   <Row>
    <Cell><Data ss:Type="String">Value</Data></Cell>
    <Cell><Data ss:Type="Number">123</Data></Cell>
   </Row>
  </Table>
 </Worksheet>
</Workbook>

Current file extensions

Microsoft Excel 2007, along with the other products in the Microsoft Office 2007 suite, introduced new file formats. The first of these (.xlsx) is defined in the Office Open XML (OOXML) specification.

Excel 2007 formats

Format Extension Description
Excel Workbook .xlsx The default Excel 2007 and later workbook format. In reality, a ZIP compressed archive with a directory structure of XML text documents. Functions as the primary replacement for the former binary .xls format, although it does not support Excel macros for security reasons. Saving as .xlsx offers file size reduction over .xls[33]
Excel Macro-enabled Workbook .xlsm As Excel Workbook, but with macro support.
Excel Binary Workbook .xlsb As Excel Macro-enabled Workbook, but storing information in binary form rather than XML documents for opening and saving documents more quickly and efficiently. Intended especially for very large documents with tens of thousands of rows, and/or several hundreds of columns. This format is very useful for shrinking large Excel files as is often the case when doing data analysis.
Excel Macro-enabled Template .xltm A template document that forms a basis for actual workbooks, with macro support. The replacement for the old .xlt format.
Excel Add-in .xlam Excel add-in to add extra functionality and tools. Inherent macro support because of the file purpose.

Old file extensions

Format Extension Description
Spreadsheet .xls Main spreadsheet format which holds data in worksheets, charts, and macros
Add-in (VBA) .xla Adds custom functionality; written in VBA
Toolbar .xlb The file extension where Microsoft Excel custom toolbar settings are stored.
Chart .xlc A chart created with data from a Microsoft Excel spreadsheet that only saves the chart. To save the chart and spreadsheet save as .XLS. XLC is not supported in Excel 2007 or in any newer versions of Excel.
Dialog .xld Used in older versions of Excel.
Archive .xlk A backup of an Excel Spreadsheet
Add-in (DLL) .xll Adds custom functionality; written in C++/C, Fortran, etc. and compiled in to a special dynamic-link library
Macro .xlm A macro is created by the user or pre-installed with Excel.
Template .xlt A pre-formatted spreadsheet created by the user or by Microsoft Excel.
Module .xlv A module is written in VBA (Visual Basic for Applications) for Microsoft Excel
Library .DLL Code written in VBA may access functions in a DLL, typically this is used to access the Windows API
Workspace .xlw Arrangement of the windows of multiple Workbooks

Using other Windows applications

Windows applications such as Microsoft Access and Microsoft Word, as well as Excel can communicate with each other and use each other’s capabilities. The most common are Dynamic Data Exchange: although strongly deprecated by Microsoft, this is a common method to send data between applications running on Windows, with official MS publications referring to it as «the protocol from hell».[34] As the name suggests, it allows applications to supply data to others for calculation and display. It is very common in financial markets, being used to connect to important financial data services such as Bloomberg and Reuters.

OLE Object Linking and Embedding allows a Windows application to control another to enable it to format or calculate data. This may take on the form of «embedding» where an application uses another to handle a task that it is more suited to, for example a PowerPoint presentation may be embedded in an Excel spreadsheet or vice versa.[35][36][37][38]

Using external data

Excel users can access external data sources via Microsoft Office features such as (for example) .odc connections built with the Office Data Connection file format. Excel files themselves may be updated using a Microsoft supplied ODBC driver.

Excel can accept data in real-time through several programming interfaces, which allow it to communicate with many data sources such as Bloomberg and Reuters (through addins such as Power Plus Pro).

  • DDE: «Dynamic Data Exchange» uses the message passing mechanism in Windows to allow data to flow between Excel and other applications. Although it is easy for users to create such links, programming such links reliably is so difficult that Microsoft, the creators of the system, officially refer to it as «the protocol from hell».[34] In spite of its many issues DDE remains the most common way for data to reach traders in financial markets.
  • Network DDE Extended the protocol to allow spreadsheets on different computers to exchange data. Starting with Windows Vista, Microsoft no longer supports the facility.[39]
  • Real Time Data: RTD although in many ways technically superior to DDE, has been slow to gain acceptance, since it requires non-trivial programming skills, and when first released was neither adequately documented nor supported by the major data vendors.[40][41]

Alternatively, Microsoft Query provides ODBC-based browsing within Microsoft Excel.[42][43][44]

Export and migration of spreadsheets

Programmers have produced APIs to open Excel spreadsheets in a variety of applications and environments other than Microsoft Excel. These include opening Excel documents on the web using either ActiveX controls, or plugins like the Adobe Flash Player. The Apache POI opensource project provides Java libraries for reading and writing Excel spreadsheet files.

Password protection

Microsoft Excel protection offers several types of passwords:

  • Password to open a document[45]
  • Password to modify a document[46]
  • Password to unprotect the worksheet
  • Password to protect workbook
  • Password to protect the sharing workbook[47]

All passwords except password to open a document can be removed instantly regardless of the Microsoft Excel version used to create the document. These types of passwords are used primarily for shared work on a document. Such password-protected documents are not encrypted, and a data sources from a set password is saved in a document’s header. Password to protect workbook is an exception – when it is set, a document is encrypted with the standard password «VelvetSweatshop», but since it is known to the public, it actually does not add any extra protection to the document. The only type of password that can prevent a trespasser from gaining access to a document is password to open a document. The cryptographic strength of this kind of protection depends strongly on the Microsoft Excel version that was used to create the document.

In Microsoft Excel 95 and earlier versions, the password to open is converted to a 16-bit key that can be instantly cracked. In Excel 97/2000 the password is converted to a 40-bit key, which can also be cracked very quickly using modern equipment. As regards services that use rainbow tables (e.g. Password-Find), it takes up to several seconds to remove protection. In addition, password-cracking programs can brute-force attack passwords at a rate of hundreds of thousands of passwords a second, which not only lets them decrypt a document but also find the original password.

In Excel 2003/XP the encryption is slightly better – a user can choose any encryption algorithm that is available in the system (see Cryptographic Service Provider). Due to the CSP, an Excel file cannot be decrypted, and thus the password to open cannot be removed, though the brute-force attack speed remains quite high. Nevertheless, the older Excel 97/2000 algorithm is set by the default. Therefore, users who do not change the default settings lack reliable protection of their documents.

The situation changed fundamentally in Excel 2007, where the modern AES algorithm with a key of 128 bits started being used for decryption, and a 50,000-fold use of the hash function SHA1 reduced the speed of brute-force attacks down to hundreds of passwords per second. In Excel 2010, the strength of the protection by the default was increased two times due to the use of a 100,000-fold SHA1 to convert a password to a key.

Other platforms

Excel for mobile

Excel Mobile is a spreadsheet program that can edit XLSX files. It can edit and format text in cells, calculate formulas, search within the spreadsheet, sort rows and columns, freeze panes, filter the columns, add comments, and create charts. It cannot add columns or rows except at the edge of the document, rearrange columns or rows, delete rows or columns, or add spreadsheet tabs.[48][49][50][51][52][53] The 2007 version has the ability to use a full-screen mode to deal with limited screen resolution, as well as split panes to view different parts of a worksheet at one time.[51] Protection settings, zoom settings, autofilter settings, certain chart formatting, hidden sheets, and other features are not supported on Excel Mobile, and will be modified upon opening and saving a workbook.[52] In 2015, Excel Mobile became available for Windows 10 and Windows 10 Mobile on Windows Store.[54][55]

Excel for the web

Excel for the web is a free lightweight version of Microsoft Excel available as part of Office on the web, which also includes web versions of Microsoft Word and Microsoft PowerPoint.

Excel for the web can display most of the features available in the desktop versions of Excel, although it may not be able to insert or edit them. Certain data connections are not accessible on Excel for the web, including with charts that may use these external connections. Excel for the web also cannot display legacy features, such as Excel 4.0 macros or Excel 5.0 dialog sheets. There are also small differences between how some of the Excel functions work.[56]

Microsoft Excel Viewer

Microsoft Excel Viewer was a freeware program for Microsoft Windows for viewing and printing spreadsheet documents created by Excel.[57] Microsoft retired the viewer in April 2018 with the last security update released in February 2019 for Excel Viewer 2007 (SP3).[58][59]

The first version released by Microsoft was Excel 97 Viewer.[60][61] Excel 97 Viewer was supported in Windows CE for Handheld PCs.[62] In October 2004, Microsoft released Excel Viewer 2003.[63] In September 2007, Microsoft released Excel Viewer 2003 Service Pack 3 (SP3).[64] In January 2008, Microsoft released Excel Viewer 2007 (featuring a non-collapsible Ribbon interface).[65] In April 2009, Microsoft released Excel Viewer 2007 Service Pack 2 (SP2).[66] In October 2011, Microsoft released Excel Viewer 2007 Service Pack 3 (SP3).[67]

Microsoft advises to view and print Excel files for free to use the Excel Mobile application for Windows 10 and for Windows 7 and Windows 8 to upload the file to OneDrive and use Excel for the web with a Microsoft account to open them in a browser.[58][68]

Quirks

In addition to issues with spreadsheets in general, other problems specific to Excel include numeric precision, misleading statistics functions, mod function errors, date limitations and more.

Numeric precision

Excel maintains 15 figures in its numbers, but they are not always accurate: the bottom line should be the same as the top line.

Despite the use of 15-figure precision, Excel can display many more figures (up to thirty) upon user request. But the displayed figures are not those actually used in its computations, and so, for example, the difference of two numbers may differ from the difference of their displayed values. Although such departures are usually beyond the 15th decimal, exceptions do occur, especially for very large or very small numbers. Serious errors can occur if decisions are made based upon automated comparisons of numbers (for example, using the Excel If function), as equality of two numbers can be unpredictable.[citation needed]

In the figure, the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using Excel. Because the sum in the second line has only eleven 1’s after the decimal, the difference when 1 is subtracted from this displayed value is three 0’s followed by a string of eleven 1’s. However, the difference reported by Excel in the third line is three 0’s followed by a string of thirteen 1’s and two extra erroneous digits. This is because Excel calculates with about half a digit more than it displays.

Excel works with a modified 1985 version of the IEEE 754 specification.[69] Excel’s implementation involves conversions between binary and decimal representations, leading to accuracy that is on average better than one would expect from simple fifteen digit precision, but that can be worse. See the main article for details.

Besides accuracy in user computations, the question of accuracy in Excel-provided functions may be raised. Particularly in the arena of statistical functions, Excel has been criticized for sacrificing accuracy for speed of calculation.[70][71]

As many calculations in Excel are executed using VBA, an additional issue is the accuracy of VBA, which varies with variable type and user-requested precision.[72]

Statistical functions

The accuracy and convenience of statistical tools in Excel has been criticized,[73][74][75][76][77] as mishandling missing data, as returning incorrect values due to inept handling of round-off and large numbers, as only selectively updating calculations on a spreadsheet when some cell values are changed, and as having a limited set of statistical tools. Microsoft has announced some of these issues are addressed in Excel 2010.[78]

Excel MOD function error

Excel has issues with modulo operations. In the case of excessively large results, Excel will return the error warning #NUM! instead of an answer.[79]

Fictional leap day in the year 1900

Excel includes February 29, 1900, incorrectly treating 1900 as a leap year, even though e.g. 2100 is correctly treated as a non-leap year.[80][81] The bug originated from Lotus 1-2-3 (deliberately implemented to save computer memory), and was also purposely implemented in Excel, for the purpose of bug compatibility.[82] This legacy has later been carried over into Office Open XML file format.[83]

Thus a (not necessarily whole) number greater than or equal to 61 interpreted as a date and time are the (real) number of days after December 30, 1899, 0:00, a non-negative number less than 60 is the number of days after December 31, 1899, 0:00, and numbers with whole part 60 represent the fictional day.

Date range

Excel supports dates with years in the range 1900–9999, except that December 31, 1899, can be entered as 0 and is displayed as 0-jan-1900.

Converting a fraction of a day into hours, minutes and days by treating it as a moment on the day January 1, 1900, does not work for a negative fraction.[84]

Conversion problems

Entering text that happens to be in a form that is interpreted as a date, the text can be unintentionally changed to a standard date format. A similar problem occurs when a text happens to be in the form of a floating-point notation of a number. In these cases the original exact text cannot be recovered from the result. Formatting the cell as TEXT before entering ambiguous text prevents Excel from converting to a date.

This issue has caused a well known problem in the analysis of DNA, for example in bioinformatics. As first reported in 2004,[85] genetic scientists found that Excel automatically and incorrectly converts certain gene names into dates. A follow-up study in 2016 found many peer reviewed scientific journal papers had been affected and that «Of the selected journals, the proportion of published articles with Excel files containing gene lists that are affected by gene name errors is 19.6 %.»[86] Excel parses the copied and pasted data and sometimes changes them depending on what it thinks they are. For example, MARCH1 (Membrane Associated Ring-CH-type finger 1) gets converted to the date March 1 (1-Mar) and SEPT2 (Septin 2) is converted into September 2 (2-Sep) etc.[87] While some secondary news sources[88] reported this as a fault with Excel, the original authors of the 2016 paper placed the blame with the researchers misusing Excel.[86][89]

In August 2020 the HUGO Gene Nomenclature Committee (HGNC) published new guidelines in the journal Nature regarding gene naming in order to avoid issues with «symbols that affect data handling and retrieval.» So far 27 genes have been renamed, including changing MARCH1 to MARCHF1 and SEPT1 to SEPTIN1 in order to avoid accidental conversion of the gene names into dates.[90]

Errors with large strings

The following functions return incorrect results when passed a string longer than 255 characters:[91]

  • type() incorrectly returns 16, meaning «Error value»
  • IsText(), when called as a method of the VBA object WorksheetFunction (i.e., WorksheetFunction.IsText() in VBA), incorrectly returns «false».

Filenames

Microsoft Excel will not open two documents with the same name and instead will display the following error:

A document with the name ‘%s’ is already open. You cannot open two documents with the same name, even if the documents are in different folders. To open the second document, either close the document that is currently open, or rename one of the documents.[92]

The reason is for calculation ambiguity with linked cells. If there is a cell ='[Book1.xlsx]Sheet1'!$G$33, and there are two books named «Book1» open, there is no way to tell which one the user means.[93]

Versions

Early history

Microsoft originally marketed a spreadsheet program called Multiplan in 1982. Multiplan became very popular on CP/M systems, but on MS-DOS systems it lost popularity to Lotus 1-2-3. Microsoft released the first version of Excel for the Macintosh on September 30, 1985, and the first Windows version was 2.05 (to synchronize with the Macintosh version 2.2) on November 19, 1987.[94][95] Lotus was slow to bring 1-2-3 to Windows and by the early 1990s, Excel had started to outsell 1-2-3 and helped Microsoft achieve its position as a leading PC software developer. This accomplishment solidified Microsoft as a valid competitor and showed its future of developing GUI software. Microsoft maintained its advantage with regular new releases, every two years or so.

Microsoft Windows

Excel 2.0 is the first version of Excel for the Intel platform. Versions prior to 2.0 were only available on the Apple Macintosh.

Excel 2.0 (1987)

The first Windows version was labeled «2» to correspond to the Mac version. It was announced on October 6, 1987, and released on November 19.[96] This included a run-time version of Windows.[97]

BYTE in 1989 listed Excel for Windows as among the «Distinction» winners of the BYTE Awards. The magazine stated that the port of the «extraordinary» Macintosh version «shines», with a user interface as good as or better than the original.

Excel 3.0 (1990)

Included toolbars, drawing capabilities, outlining, add-in support, 3D charts, and many more new features.[97]

Excel 4.0 (1992)

Introduced auto-fill.[98]

Also, an easter egg in Excel 4.0 reveals a hidden animation of a dancing set of numbers 1 through 3, representing Lotus 1-2-3, which is then crushed by an Excel logo.[99]

Excel 5.0 (1993)

With version 5.0, Excel has included Visual Basic for Applications (VBA), a programming language based on Visual Basic which adds the ability to automate tasks in Excel and to provide user-defined functions (UDF) for use in worksheets. VBA includes a fully featured integrated development environment (IDE). Macro recording can produce VBA code replicating user actions, thus allowing simple automation of regular tasks. VBA allows the creation of forms and in‑worksheet controls to communicate with the user. The language supports use (but not creation) of ActiveX (COM) DLL’s; later versions add support for class modules allowing the use of basic object-oriented programming techniques.

The automation functionality provided by VBA made Excel a target for macro viruses. This caused serious problems until antivirus products began to detect these viruses. Microsoft belatedly took steps to prevent the misuse by adding the ability to disable macros completely, to enable macros when opening a workbook or to trust all macros signed using a trusted certificate.

Versions 5.0 to 9.0 of Excel contain various Easter eggs, including a «Hall of Tortured Souls», a Doom-like minigame, although since version 10 Microsoft has taken measures to eliminate such undocumented features from their products.[100]

5.0 was released in a 16-bit x86 version for Windows 3.1 and later in a 32-bit version for NT 3.51 (x86/Alpha/PowerPC)

Excel 95 (v7.0)

Released in 1995 with Microsoft Office for Windows 95, this is the first major version after Excel 5.0, as there is no Excel 6.0 with all of the Office applications standardizing on the same major version number.

Internal rewrite to 32-bits. Almost no external changes, but faster and more stable.

Excel 95 contained a hidden Doom-like mini-game called «The Hall of Tortured Souls», a series of rooms featuring the names and faces of the developers as an easter egg.[101]

Excel 97 (v8.0)

Included in Office 97 (for x86 and Alpha). This was a major upgrade that introduced the paper clip office assistant and featured standard VBA used instead of internal Excel Basic. It introduced the now-removed Natural Language labels.

This version of Excel includes a flight simulator as an Easter Egg.

Excel 2000 (v9.0)

Included in Office 2000. This was a minor upgrade but introduced an upgrade to the clipboard where it can hold multiple objects at once. The Office Assistant, whose frequent unsolicited appearance in Excel 97 had annoyed many users, became less intrusive.

A small 3-D game called «Dev Hunter» (inspired by Spy Hunter) was included as an easter egg.[102][103]

Excel 2002 (v10.0)

Included in Office XP. Very minor enhancements.

Excel 2003 (v11.0)

Included in Office 2003. Minor enhancements.

Excel 2007 (v12.0)

Included in Office 2007. This release was a major upgrade from the previous version. Similar to other updated Office products, Excel in 2007 used the new Ribbon menu system. This was different from what users were used to, and was met with mixed reactions. One study reported fairly good acceptance by users except highly experienced users and users of word processing applications with a classical WIMP interface, but was less convinced in terms of efficiency and organization.[104] However, an online survey reported that a majority of respondents had a negative opinion of the change, with advanced users being «somewhat more negative» than intermediate users, and users reporting a self-estimated reduction in productivity.

Added functionality included Tables,[105] and the SmartArt set of editable business diagrams. Also added was an improved management of named variables through the Name Manager, and much-improved flexibility in formatting graphs, which allow (x, y) coordinate labeling and lines of arbitrary weight. Several improvements to pivot tables were introduced.

Also like other office products, the Office Open XML file formats were introduced, including .xlsm for a workbook with macros and .xlsx for a workbook without macros.[106]

Specifically, many of the size limitations of previous versions were greatly increased. To illustrate, the number of rows was now 1,048,576 (220) and columns was 16,384 (214; the far-right column is XFD). This changes what is a valid A1 reference versus a named range. This version made more extensive use of multiple cores for the calculation of spreadsheets; however, VBA macros are not handled in parallel and XLL add‑ins were only executed in parallel if they were thread-safe and this was indicated at registration.

Excel 2010 (v14.0)

Microsoft Excel 2010 running on Windows 7

Included in Office 2010, this is the next major version after v12.0, as version number 13 was skipped.

Minor enhancements and 64-bit support,[107] including the following:

  • Multi-threading recalculation (MTR) for commonly used functions
  • Improved pivot tables
  • More conditional formatting options
  • Additional image editing capabilities
  • In-cell charts called sparklines
  • Ability to preview before pasting
  • Office 2010 backstage feature for document-related tasks
  • Ability to customize the Ribbon
  • Many new formulas, most highly specialized to improve accuracy[108]

Excel 2013 (v15.0)

Included in Office 2013, along with a lot of new tools included in this release:

  • Improved Multi-threading and Memory Contention
  • FlashFill[109]
  • Power View[110]
  • Power Pivot[111]
  • Timeline Slicer
  • Windows App
  • Inquire[112]
  • 50 new functions[113]

Excel 2016 (v16.0)

Included in Office 2016, along with a lot of new tools included in this release:

  • Power Query integration
  • Read-only mode for Excel
  • Keyboard access for Pivot Tables and Slicers in Excel
  • New Chart Types
  • Quick data linking in Visio
  • Excel forecasting functions
  • Support for multiselection of Slicer items using touch
  • Time grouping and Pivot Chart Drill Down
  • Excel data cards[114]

Excel 2019, Excel 2021, Office 365 and subsequent (v16.0)

Microsoft no longer releases Office or Excel in discrete versions. Instead, features are introduced automatically over time using Windows Update. The version number remains 16.0. Thereafter only the approximate dates when features appear can now be given.

  • Dynamic Arrays. These are essentially Array Formulas but they «Spill» automatically into neighboring cells and does not need the ctrl-shift-enter to create them. Further, dynamic arrays are the default format, with new «@» and «#» operators to provide compatibility with previous versions. This is perhaps the biggest structural change since 2007, and is in response to a similar feature in Google Sheets. Dynamic arrays started appearing in pre-releases about 2018, and as of March 2020 are available in published versions of Office 365 provided a user selected «Office Insiders».

Impact

Excel offers many user interface tweaks over the earliest electronic spreadsheets; however, the essence remains the same as in the original spreadsheet software, VisiCalc: the program displays cells organized in rows and columns, and each cell may contain data or a formula, with relative or absolute references to other cells.

Excel 2.0 for Windows, which was modeled after its Mac GUI-based counterpart, indirectly expanded the installed base of the then-nascent Windows environment. Excel 2.0 was released a month before Windows 2.0, and the installed base of Windows was so low at that point in 1987 that Microsoft had to bundle a runtime version of Windows 1.0 with Excel 2.0.[117] Unlike Microsoft Word, there never was a DOS version of Excel.

Excel became the first spreadsheet to allow the user to define the appearance of spreadsheets (fonts, character attributes, and cell appearance). It also introduced intelligent cell re-computation, where only cells dependent on the cell being modified are updated (previous spreadsheet programs recomputed everything all the time or waited for a specific user command). Excel introduced auto-fill, the ability to drag and expand the selection box to automatically copy a cell or row contents to adjacent cells or rows, adjusting the copies intelligently by automatically incrementing cell references or contents. Excel also introduced extensive graphing capabilities.

Security

Because Excel is widely used, it has been attacked by hackers. While Excel is not directly exposed to the Internet, if an attacker can get a victim to open a file in Excel, and there is an appropriate security bug in Excel, then the attacker can gain control of the victim’s computer.[118] UK’s GCHQ has a tool named TORNADO ALLEY with this purpose.[119][120]

Games

Besides the easter eggs, numerous games have been created or recreated in Excel, such as Tetris, 2048, Scrabble, Yahtzee, Angry Birds, Pac-Man, Civilization, Monopoly, Battleship, Blackjack, Space Invaders, and others.[121][122][123][124][125]

In 2020, Excel became an esport with the advent of the Financial Modeling World Cup.[126]

  • Microsoft Excel – official site

Excel is an electronic spreadsheet program that is used for storing, organizing, and manipulating data.

The information we’ve prepared refers to Microsoft Excel in general and is not limited to any specific version of the program.

What Excel Is Used For

Electronic spreadsheet programs were originally based on paper spreadsheets used for accounting. As such, the basic layout of computerized spreadsheets is the same as the paper ones. Related data is stored in tables — which are a collection of small rectangular boxes or cells organized into rows and columns.

All versions of Excel and other spreadsheet programs can store several spreadsheet pages in a single computer file. The saved computer file is often referred to as a workbook and each page in the workbook is a separate worksheet.

Spreadsheet Cells and Cell References

When you look at the Excel screen — or any other spreadsheet screen — you see a rectangular table or grid of rows and columns.

In newer versions of Excel, each worksheet contains roughly a million rows and more than 16,000 columns, which necessitates an addressing scheme in order to keep track of where data is located.

The horizontal rows are identified by numbers (1, 2, 3) and the vertical columns by letters of the alphabet (A, B, C). For columns beyond 26, columns are identified by two or more letters such as AA, AB, AC or AAA, AAB, etc.

The intersection point between a column and a row is the small rectangular box known as a cell. The cell is the basic unit for storing data in the worksheet, and because each worksheet contains millions of these cells, each one is identified by its cell reference.

A cell reference is a combination of the column letter and the row number such as A3, B6, and AA345. In these cell references, the column letter is always listed first.

Data Types, Formulas, and Functions

The types of data that a cell can hold include:

  • Numbers
  • Text
  • Dates and times
  • Boolean values
  • Formulas

Formulas are used for calculations — usually incorporating data contained in other cells. These cells, however, may be located on different worksheets or in different workbooks.

Creating a formula starts by entering the equal sign in the cell where you want the answer displayed. Formulas can also include cell references to the location of data and one or more spreadsheet functions.

Functions in Excel and other electronic spreadsheets are built-in formulas that are designed to simplify carrying out a wide range of calculations – from common operations such as entering the date or time to more complex ones such as finding specific information located in large tables of data.

Excel and Financial Data

Spreadsheets are often used to store financial data. Formulas and functions that are used on this type of data include:

  • Performing basic mathematical operations such as summing columns or rows of numbers
  • Finding values such as profit or loss
  • Calculating repayment plans for loans or mortgages
  • Finding the average, maximum, minimum and other statistical values in a specified range of data
  • Carrying out What-If analysis on data, where variables are modified one at a time to see how the change affects other data, such as expenses and profits

Excel’s Other Uses

Other common operations that Excel can be used for include:

  • Graphing or charting data to assist users in identifying data trends
  • Formatting data to make important data easy to find and understand
  • Printing data and charts for use in reports
  • Sorting and filtering data to find specific information
  • Linking worksheet data and charts for use in other programs such as Microsoft PowerPoint and Word
  • Importing data from database programs for analysis

Spreadsheets were the original «killer apps» for personal computers because of their ability to compile and make sense of information. Early spreadsheet programs such as VisiCalc and Lotus 1-2-3 were largely responsible for the growth in popularity of computers like the Apple II and the IBM PC as a business tool.

Excel Alternatives

Other current spreadsheet programs that are available for use include:

  • Google Sheets: A free, web-based spreadsheet program
  • Excel Online: A free, scaled-down, web-based version of Excel
  • Open Office Calc: A free, downloadable spreadsheet program.

Microsoft Excel

Excel is a spreadsheet application developed and published by Microsoft. It is part of the Microsoft Office suite of productivity software.

Unlike a word processor, such as Microsoft Word, Excel organizes data in columns and rows. Rows and columns intersect at a space called a cell. Each cell contains data, such as text, a numerical value, or a formula.

Excel was originally code-named Odyssey during development. It was first released on September 30, 1985.

Excel overview

Excel is a tool for organizing and performing calculations on data. It can analyze data, calculate statistics, generate pivot tables, and represent data as charts or graphs.

For example, you could create an Excel spreadsheet that calculates a monthly budget, tracks associated expenses, and interactively sorts the data by criteria.

Below is an example of Microsoft Excel with each of its major sections highlighted. See the formula bar, cell, column, row, or sheet tab links for further information about each section.

Microsoft Excel spreadsheet

Where do you find or start Excel?

If you have Excel or the entire Microsoft Office package installed on your Windows computer, you can find Excel in the Start menu.

Keep in mind that new computers do not include Excel. It must be purchased and installed before running it on your computer. If you do not want (or cannot afford) to purchase Excel, you can use a limited version for free at the Microsoft Office website.

If Excel is installed on your computer but isn’t in your Start menu, use the following steps to launch Excel manually.

  1. Open My Computer or File Explorer.
  2. Click or select the C: drive. If Microsoft Office is installed on a drive other than the C: drive, select that drive instead.
  3. Find and open the Program Files (x86) or Program Files folder.
  4. Open the Microsoft Office folder.
  5. In the Microsoft Office folder, open the root folder. Then open the OfficeXX folder, where XX is the version of Microsoft Office (e.g., Office16 for Microsoft Office 2016) installed on your computer.

Tip

If there is no root folder, look for and open the folder with Office in the folder name.

  1. Find and double-click the file named EXCEL.EXE to start the Excel program.

How to open Microsoft Excel without using a mouse

  1. Press the Windows key.
  2. Type Excel and select the Microsoft Excel entry in the search results.
  3. If Excel does not open after selecting it in the search results, press Enter to launch it.

How can Excel be formatted?

Each of the rows, columns, and cells can be modified in many ways, including the background color, number or date format, size, text font, layout, etc. In our example above, you can see that the first row (row 1) has a blue background, bold text, and each cell has its text centered.

Download an example of a spreadsheet file

We created a Microsoft Excel spreadsheet that you can download and open in any spreadsheet program, including Microsoft Excel. This spreadsheet illustrates some capabilities of a spreadsheet, formulas, and functions, and lets you experiment more with a spreadsheet.

  • Download example.xls

Why do people use Excel?

There are many reasons people use Excel. For example, someone might use Excel and a spreadsheet to keep track of their expenses. See our spreadsheet definition for a complete list of reasons and examples of how people use a spreadsheet.

Why would someone use Excel over another spreadsheet program?

Today, there are many free spreadsheet programs that someone could use instead of Excel. However, even with the available free options, Excel remains the most-used spreadsheet because of all its available options, features, and because many businesses still use the program.

  • Where can I get a free spreadsheet program?

Tip

Even with all Excel’s options, a free spreadsheet program like Google Sheets is often all most users need.

Note

If you want to get Excel because it’s a job requirement, it’s still okay to learn all the basics in a free spreadsheet program. However, there are still many differences between Excel and a free spreadsheet program.

What is Microsoft Excel?

Microsoft Excel is a spreadsheet program used to record and analyze numerical and statistical data. Microsoft Excel provides multiple features to perform various operations like calculations, pivot tables, graph tools, macro programming, etc. It is compatible with multiple OS like Windows, macOS, Android and iOS.

A Excel spreadsheet can be understood as a collection of columns and rows that form a table. Alphabetical letters are usually assigned to columns, and numbers are usually assigned to rows. The point where a column and a row meet is called a cell. The address of a cell is given by the letter representing the column and the number representing a row.

Why Should I Learn Microsoft Excel?

We all deal with numbers in one way or the other. We all have daily expenses which we pay for from the monthly income that we earn. For one to spend wisely, they will need to know their income vs. expenditure. Microsoft Excel comes in handy when we want to record, analyze and store such numeric data. Let’s illustrate this using the following image.

The ribbon provides shortcuts to commands in Excel. A command is an action that the user performs. An example of a command is creating a new document, printing a documenting, etc. The image below shows the ribbon used in Excel 2013.

Microsoft Excel Tutorial

Ribbon components explained

Ribbon start button – it is used to access commands i.e. creating new documents, saving existing work, printing, accessing the options for customizing Excel, etc.

Ribbon tabs – the tabs are used to group similar commands together. The home tab is used for basic commands such as formatting the data to make it more presentable, sorting and finding specific data within the spreadsheet.

Ribbon bar – the bars are used to group similar commands together. As an example, the Alignment ribbon bar is used to group all the commands that are used to align data together.

Understanding the worksheet (Rows and Columns, Sheets, Workbooks)

A worksheet is a collection of rows and columns. When a row and a column meet, they form a cell. Cells are used to record data. Each cell is uniquely identified using a cell address. Columns are usually labelled with letters while rows are usually numbers.

A workbook is a collection of worksheets. By default, a workbook has three cells in Excel. You can delete or add more sheets to suit your requirements. By default, the sheets are named Sheet1, Sheet2 and so on and so forth. You can rename the sheet names to more meaningful names i.e. Daily Expenses, Monthly Budget, etc.

Microsoft Excel 800px-Microsoft Office Excel (2018–present).svg.png is a spreadsheet application written and distributed by Microsoft for Windows, macOS, Android, and iOS. It features calculation and computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel is a part of the Microsoft Office productivity suite.

History

Early history

Microsoft originally marketed a spreadsheet program called Multiplan in 1982, which was very popular on CP/M systems, but on MS-DOS systems it lost popularity to Lotus 1-2-3. Microsoft released the first version of Excel for the Macintosh on September 30, 1985, and the first Windows version was 2.05 (to synchronize with Macintosh version 2.2) on November 19, 1987. Lotus was slow to bring 1-2-3 to Windows and by the early 1990s, Excel had started to outsell 1-2-3 and helped Microsoft achieve the position of leading PC software developer. This accomplishment, dethroning the king of the software world, solidified Microsoft as a valid competitor and showed its future of developing GUI software. Microsoft pushed its advantage with regular new releases, every two years or so.

Microsoft Excel 2.1 included a runtime version of Windows 2.1

Early in its life Excel became the target of a trademark lawsuit by another company already selling a software package named «Excel» in the finance industry. As the result of the dispute Microsoft was required to refer to the program as «Microsoft Excel» in all of its formal press releases and legal documents. However, over time this practice has been ignored, and Microsoft cleared up the issue permanently when they purchased the trademark of the other program. Microsoft also encouraged the use of the letters XL as shorthand for the program; while this is no longer common, the program’s icon on Windows still consists of a stylized combination of the two letters, and the file extension of the default Excel format is .xls.
Excel offers many user interface tweaks over the earliest electronic spreadsheets; however, the essence remains the same as in the original spreadsheet, VisiCalc: the cells are organized in rows and columns, and contain data or formulas with relative or absolute references to other cells.

Excel was the first spreadsheet that allowed the user to define the appearance of spreadsheets (fonts, character attributes and cell appearance). It also introduced intelligent cell recomputation, where only cells dependent on the cell being modified are updated (previous spreadsheet programs recomputed everything all the time or waited for a specific user command). Excel has extensive graphing capabilities.

When first bundled into Microsoft Office in 1993, Microsoft Word and Microsoft PowerPoint had their GUIs redesigned for consistency with Excel, the killer app on the PC at the time.

Since 1993, Excel has included Visual Basic for Applications (VBA), a programming language based on Visual Basic which adds the ability to automate tasks in Excel and to provide user defined functions (UDF) for use in worksheets. VBA is a powerful addition to the application which, in later versions, includes a fully featured integrated development environment (IDE). Macro recording can produce VBA code replicating user actions, thus allowing simple automation of regular tasks. VBA allows the creation of forms and in-worksheet controls to communicate with the user. The language supports use (but not creation) of ActiveX (COM) DLL‘s; later versions add support for class modules allowing the use of basic object-oriented programming techniques.

The automation functionality provided by VBA has caused Excel to become a target for macro viruses. This was a serious problem in the corporate world until antivirus products began to detect these viruses. Microsoft belatedly took steps to prevent the misuse by adding the ability to disable macros completely, to enable macros when opening a workbook or to trust all macros signed using a trusted certificate.

Versions 5.0 to 9.0 of Excel contain various Easter eggs, although since version 10 Microsoft has taken measures to eliminate such undocumented features from their products.

File formats

Microsoft Excel up until 2007 version used a proprietary binary file format called Binary Interchange File Format (BIFF) as its primary format. Excel 2007 uses Office Open XML as its primary file format, an XML-based container similar in design to XML-based format called «XML Spreadsheet» («XMLSS»), first introduced in Excel 2002. The latter format is not able to encode VBA macros.

Although supporting and encouraging the use of new XML-based formats as replacements, Excel 2007 is still backwards compatible with the traditional, binary, formats. In addition, most versions of Microsoft Excel are able to read CSV, DBF, SYLK, DIF, and other legacy formats.

Microsoft Excel 2007 Office Open XML formats

Microsoft Excel 2007, along with the other products in the Microsoft Office 2007 suite, introduces a host of new file formats. These are part of the Office Open XML (OOXML) specification.

The new Excel 2007 formats are:

Excel Workbook (.xlsx)
The default Excel 2007 workbook format. In reality a ZIP compressed archive with a directory structure of XML text documents. Functions as the primary replacement for the former binary .xls format, although it does not support Excel macros for security reasons.
Excel Macro-enabled Workbook (.xlsm)
As Excel Workbook, but with macro support.
Excel Binary Workbook (.xlsb)
As Excel Macro-enabled Workbook, but storing information in binary form rather than XML documents for opening and saving documents more quickly and efficiently. Intended especially for very large documents with tens of thousands of rows, and/or several hundreds of columns.
Excel Macro-enabled Template (.xltm)
A template document that forms a basis for actual workbooks, with macro support. The replacement for the old .xlt format.
Excel Add-in (.xlam)
Excel add-in to add extra functionality and tools. Inherent macro support due to the file purpose.

Exporting and Migration of spreadsheets

APIs are also provided to open excel spreadsheets in a variety of other applications and environments other than Microsoft Excel. These include opening excel documents on the web using either ActiveX controls,or plugins like the Adobe Flash Player. Attempts have also been made to be able to copy excel spreadsheets to web applications using comma-separated values].

Criticism

Due to Excel’s foundation on floating point calculations, the statistical accuracy of Excel has been criticized, as has the lack of certain statistical tools. Excel proponents have responded that some of these errors represent edge cases and that the relatively few users who would be affected by these know of them and have workarounds and alternatives.

Excel incorrectly assumes that 1900 is a leap year. The bug originated from Lotus 1-2-3, and was implemented in Excel for the purpose of backward compatibility. This legacy has later been carried over into Office Open XML file format. Excel also supports the second date format based on year 1904 epoch.

Criticisms of spreadsheets in general also apply significantly to Excel. See Spreadsheet shortcomings.

Errors in Excel 2007

Screen shot of Microsoft Excel 2007 showing the 65,535 display error

On September 22, 2007 it was reported that Excel 2007 will show incorrect results in certain situations. Specifically, for some pairs of numbers with a product of 65,535 (such as 850 and 77.1), Excel will report their product as 100,000. This occurs with about 14.5% of such pairs. In addition, if one is added to this result, Excel will give 100,001. However, if one is subtracted from the original product, the correct result of 65,534 is reported. (Also if it is multiplied or divided by 2, the correct answers 131,070 and 32,767.5 are reported, respectively.)

Microsoft has reported on the Microsoft Excel Blog that the problem exists in the display of six specific floating point values between 65534.99999999995 and 65,535, and six values between 65535.99999999995 and 65,536 (not including the integers). Any calculation that results in one of these twelve values will be displayed incorrectly. The actual value stored and passed to other cells is correct, only the displayed value is wrong. However, some instances, such as rounding the value to zero decimal places, will result in an incorrect value in memory. The error was introduced with changes made to the Excel calculation logic for the 2007 version, and does not exist in previous versions. On October 9, 2007, Microsoft released a fix to the public.
Chris Lomont presented a detailed explanation of the bug, how it was likely caused by changing 16-bit formatting code to 32-bit code, why it only affects 12 values and then only while formatting, and how the hotfix corrects the bug.
