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

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

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

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.

Old file extensions

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

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)

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]

Summary

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]

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

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.

Thanks for letting us know!

Microsoft Excel is a program in the Office 365 suite typically used to store, sort, and manipulate data. Although Excel is not a database, it is often used in data analytics and finance careers to assess large amounts of information and create visualizations. It’s also a commonly used tool in project management to organize information and track details.

What Is Microsoft Excel Used For?

Microsoft Excel is a spreadsheet program consisting of cells organized by lettered columns and numbered rows. This grid pattern allows for easy data manipulation and conversion of data into mathematical formulas. Excel is typically included as part of the Microsoft Office 365 software suite. 

Beyond basic calculations, Excel is great for data visualization, allowing you to create bar charts, scatter plots, graphs, and histograms from sets of information. Additionally, you can use Excel for data analysis using pivot tables and macro programming using Visual Basic for Application (VBA) — a programming language that allows you to automate tasks across Microsoft Office applications. 

You can also use Excel for organizing schedules, task management, customer relationship management, and time management. It’s also an excellent tool for creating personal budgets and schedules. 

Who Uses Microsoft Excel?

Many careers in finance rely on Excel for a variety of functions. For example, investment bankers use Excel to create financial models and analyze financial data. Accountants use Excel to track and report financial details and create budgets and reports. Outside of finance, data analysts across nearly every industry rely on Excel for data analysis and visualization. 

How to Use Microsoft Excel

To use Microsoft Excel, you’ll need to download the software from Microsoft’s website or the App Store. The program can be bought on its own for about $160 or as part of the full Office 365 suite for around $7 per month. Many computers come with the application pre-installed, too. A free web version of Excel is also available. 

Once you open the application, you can open a new workbook. A blank worksheet in a workbook looks like this:

With a blank workbook, you can start doing some essential Excel tasks.

Data Entry

Entering data in Excel is simple. Choose the cell you want to put information in and type.

Add Columns 

You can add columns to your worksheet by right-clicking on a column header and selecting Insert.

Add Rows

You can add rows to your worksheet by right-clicking on a row header and selecting Insert.

Freeze Rows or Columns

If you want to freeze a row or column so it stays visible as you scroll down or to the right, open the “View” menu from the navigation bar. 

Selecting “Freeze Top Row” will keep the first row of your worksheet visible as you scroll down. Similarly, selecting “Freeze First Column” will make your worksheet’s first column visible as you scroll to the side. 

Hide Columns and Rows

To hide columns, select the columns you want to hide, right-click on a header, and select hide. The process is the same for rows.

Remove Duplicates

To remove duplicate data, select the range of rows or columns where you found duplicates. Then, on the “Data” tab, click Remove Duplicates. This will prompt you to select which columns to include in the removal. You can unselect a column in the pop-up window if you don’t want to delete duplicate data from it. Then, once you click “OK,” the duplicate data will be removed, leaving empty cells.

Remove Blank Rows or Columns

We can easily remove blank rows by going to “Find & Select” on the Home tab. On this drop-down menu, choose “Go To Special…” which will give you a pop-up window of options. Here, you can click “blanks” to select all blank cells. Then, under the Delete menu, choose “Delete Cells…” 

You can have the remaining cells shift up, down, left, or right. Since we deleted rows in the middle of our data set, we want the remaining rows to shift up. 

Sum

Once you have the basics down, you can start using formulas to make calculations and manipulate data. Formulas always begin with an equal sign (=) followed by a keyword for the formula. Basic math calculations can be often completed by using the toolbar’s AutoSum function or by entering the formula into a cell. 

To find the sum of a set of numerical data, click on a blank cell and enter the formula, followed by each cell you want to be involved in the calculation, separated by commas.

For this example, we want to find the total number of each product sold for January, February, and March. So, we’ll use the formula: 

=SUM(B2,C2,D2)

When we click enter, we’ll see the total sales across those three months. 

Pro-tip: Hovering your cursor over the bottom right corner of the cell with the formula, you’ll see a plus sign. Click and drag down to apply the same function to each row and autofill. 

Average

The average function works just like the sum function, except instead, we would use the formula:

=AVERAGE(B2,C2,D2)

Concatenate

Concatenate allows you to string together cells. You can use this function to put together customer names if the first and last names are located in separate cells or combine cities and states organized in different columns. The basic formula for concatenating is:

=CONCATENATE(

You can then add specific cell coordinates in whichever order you need them. If you want to add spaces between details, include ,” “, between the cells. You can also insert anything else within quotation marks, such as commas or phrases.

In this example, we want to make a sentence saying where a music artist was born. So, we’ll use this formula (# stands for the desired row number):

=CONCATENATE(B#,” “,A#,” was born in “,C#,”,”,D#) 

Logic Functions

Logic functions follow logical thought processes. For example, if a car is red, it is a red car. These are useful functions to quickly sort information and make judgments. 

The IF function can return a specific answer or value if a cell meets a certain condition. In this example, we want to see which Q1 products had sales above 30 units. So, our formula was:

=IF(SUM(B#,C#,D#)>30, “Good”, “Bad”)

This formula essentially says, “If the sum for January, February, and March sales are greater than 30, write “Good” in this cell. If not, write “Bad.” 

Using this formula, we got these results:

The AND logic function operates in a similar way. You input what conditions you want cells to meet, and it will return either TRUE or FALSE. For example, if you input the above data, =AND(B2>5,C2<5), it will return TRUE because B2 is greater than five and C2 is less than five. 

Vlookup

The VLOOKUP function allows you to find specific information in a set of data. 

The formula for this function requires inputting what you want to find, where you want to look for it, the column number containing the information, and whether or not you want an approximate or exact match. You would input either 1 or TRUE for approximate matches, while exact matches require 0 or FALSE. 

In this example, we wanted to find the employee with ID number 3856 from the table that spans from cell A2 to cell F8. We wanted the last name pulled from column No. 2, and we wanted an exact match. 

Pivot Tables

A pivot table is a great way to organize and analyze large data sets within Excel. To create a pivot table, go to the Insert tab in the navigation bar and click “Insert Pivot Table.”

This pop-up menu will allow you to select what range of data you want to include in the pivot table and if you wish to create the table in the same worksheet or a new sheet. Once you’ve selected your data and the table destination, you’ll get this sidebar:

In this sidebar, you can choose which columns of data you want to use and where the information should go in the pivot table. For example, if you want employee first names to be the rows and sales numbers to be the columns, you can select those fields and drag them to the respective areas in the sidebar. 

Once you have the data placed where you want it, you can change how it presents itself. For example, this pivot table has employee ID numbers as the row labels, with January, February, and March sales for columns. The table defaults to showing the sum for each column (or the sum for each month’s sales).

We can change how the data is summarized, though. So, if we want to see the average sales for each month, we need to right-click that piece of data in the sidebar, select “Field Settings,” and choose “Average” from the menu labeled “Summarize by.”

Industry-Specific Excel Uses 

While the basics of Excel are the same regardless of job or industry, certain careers have specific use cases for Excel. 

Functions and Formulas for Investment Bankers

• =XNPV(discount rate, cash flows, dates): This formula will calculate the net present value (NPV) of an investment using a discounted cash flow (DCF) analysis. A similar function (=NPV) also finds NPV, except it assumes each time period is equal. Using the =XNPV formula, we can input dates manually, allowing for different time frames between cash flow amounts. 

• =XIRR(cash flows, dates): This formula calculates the internal rate of return using cash flows and specific dates. A similar formula (=IRR) can be used if the time span between each cash flow is equal. 

• =EFFECT(interest rate, number of periods per year): This formula determines the annual interest rate for rates that compound at different intervals rather than yearly time frames. So, if an interest rate compounds monthly instead of annually, this formula can determine the annual interest rate. 

• =RATE(number of periods, coupon payment per period, cost of the bond, bond face value, type): This formula can tell you the yield to maturity (YTM) rate for a security, like a bond. The number of periods is the lifetime of the bond in years, coupon payment per period is the amount paid each year, the cost of the bond is how much the bond was purchased for, and the face value is the book value of the security. 

• =FV(rate, number of periods, payments, starting value, type): This formula determines the future value of an investment if it has regular payments and a stable, compounding interest rate. 

• =SLOPE(dependent variable, independent variable): This function can calculate the Beta of a security by comparing the stock’s weekly returns (dependent variable) to a specific index (dependent variable), like the return rate average across the market or for a relatively stable security. 

Functions and Formulas for Accountants

• =DC(cost, salvage value, lifespan, current period): This formula calculates an asset’s depreciation or declining balance. The cost input should be the asset’s original cost, and salvage value is how much the asset is expected to be worth at the end of its useful life. The lifespan is how long the asset is expected to last and can be counted in months, quarters, years, or even decades. The current period is the numerical equivalent of how far into the asset’s lifespan it currently is. For example, if an asset has a five-year life expectancy, and we are already three years into that timeframe, the lifespan input would be 5, and the current period would be 3. 

• =AGGREGATE(function, ignore, cell range): This function allows you to complete a variety of calculations while ignoring any cells that have errors, are blank, or are hidden. You will be prompted to choose a function when you input the formula. These functions are numbered one through 19 and include AVERAGE, MAX, MIN, SUM, and MEDIAN. Once you’ve chosen a function, you are prompted to select what you want the formula to ignore using a menu of seven options, such as “Ignore error values” and “Ignore hidden rows.” You then input the range of cells for the formula. 

• =EOMONTH(original date, number of months forward): This formula can auto-populate the date for the last date of a month. Starting with a column of dates, you input the cell for the first date, such as 4/7/2023. Then, you enter 0 if you want the date for the end of the month you started with, 1 if you want the end date for the following month, or 2 for two months ahead. You can input -1 if you want the end date for the previous month, too. 

Functions and Formulas for Data Analysts

• =LEN(cell): This formula can tell you how many characters are in a given cell, which is helpful for data visualizations with character count limits or for determining discrepancies between strings of letters and numbers in a data set, like product codes or user identification numbers. 

• =SUBSTITUTE(cell, “original”, “replacement”): This formula quickly finds and replaces characters, spaces, or words in cells. For example, if you want to change the name of a product in a large data set, you can substitute the original name with the new replacement.  

• =TRIM(data): This formula can clean data by removing unwanted spaces from the end of cell entries. 

• =IFERROR(function,”text to display”): Errors in cells happen, and the IFERROR function allows you to have a specific text displayed if a cell has an error. For example, if a VLOOKUP cannot find a particular detail because of a typo, you could implement a safeguard to populate the cell with a message saying, “recheck original list spelling.”

How to Learn Microsoft Excel

Many resources are available to learn Microsoft Excel, regardless of skill level. Microsoft offers a free online video tutorial that gives a great overview of the basics. Both free and paid courses for Excel are available through online learning platforms, such as Udemy, edX, and freeCodeCamp. Additionally, YouTube can be an excellent resource for learning specific functions and formulas. 

Ultimately, learning Excel takes practice. Playing around with different functions within the software can help you better understand the syntax of Excel formulas and feel more comfortable manipulating data.
