Ответ: С появлением Microsoft Office 2007, компания Microsoft включила новые форматы для трех своих основных программ:

1. Microsoft Word – текстового редактора для ввода документов и писем;
2. Microsoft Excel – электронных таблиц, используемых для хранения данных в строках и столбцах и проведения расчетов по этим данным;
3. Microsoft PowerPoint – программы презентаций, используемой для профессионального создания презентаций и слайд-шоу.

Новый формат файлов
В Office 2007 (также известном как Office 12), эти три программы будут использовать новый формат файла на основе Open XML. Документы Word, Excel, PowerPoint будут сохраняться в формате XML, а не в бинарном формате. Это даст возможность при повреждении файлов, восстановить их, так как способ хранения данных в XML позволяет просмотреть файл, даже если часть документа повреждена. Например, если документ Word Open XML содержит поврежденную диаграмму, диаграмма может отображаться не корректно, но остальная часть файла должна выглядеть хорошо. Если же файл был сохранен в виде двоичного документ, он даже не может быть открыт.

Меньший размер файла
Помимо нового более совместимого формата, новые документы Office занимают меньше места по сравнению с предыдущими форматами. Это связано с тем, что новый формат использует сжатие ZIP, что позволяет уменьшить размер файла до 75%. Это экономит место на жестком диске, и полезно при отправке документов через Интернет, по электронной почте или другими способами передачи данных.

Совместимость
Поскольку XML представляет собой стандартизированный формат, Open XML документы признаются любым программным обеспечением, которое поддерживает формат Open XML. Хотя предыдущие версии офисных программ изначально не поддерживают документы, сохраненные в новом формате, компания Microsoft выпустила обновления для Office 2000, XP и 2003, которые позволяют пользователям открывать, редактировать и сохранять документы в формате Open XML.

Расширения файлов
Новые Open Office XML форматы будут включать в себя новые расширения файлов, чтобы отличить их от предыдущих типов файлов. Расширения нового и старого типов файлов, перечислены ниже:

Новое расширение	Старое расширение	Тип файлов
Microsoft Word
.DOCX	.DOC	Документ Word
.DOCM	нет	Документ Word с поддержкой макросов
.DOTX	.DOT	Шаблон
.DOTM	нет	Шаблон документа Word с поддержкой макросов
Microsoft Excel
.XLSX	.XLS	Электронная таблица Excel
.XLSM	нет	Электронная таблица Excel с поддержкой макросов
.XLTX	.XLT	Шаблон электронной таблицы Excel
.XLTM	нет	Шаблон электронной таблицы Excel с поддержкой макросов
.XLSB	нет	Двоичная книга Excel
.XLAM	.XLA	Надстройки Excel
Microsoft PowerPoint
.PPTX	.PPT	Документ презентации PowerPoint
.PPTM	нет	Документ презентации с поддержкой макросов
.PPSX	.PPS	Документ показа слайдов PowerPoint
.PPSM	нет	Документ показа слайдов PowerPoint с поддержкой макросов
.POTX	.POT	Шаблон Документа презентации PowerPoint
.POTM	нет	Шаблон Документа презентации PowerPoint с поддержкой макросов
.PPAM	.PPA	Надстройки PowerPoint

Microsoft Access
Microsoft Access 2007, также использует новый формат данных с расширением файлов .ACCDB (в предыдущих версиях Access баз данных сохранялись как .MDB файлы). Новый формат поддерживает многозначные поля, бинарные объекты, шифрование базы данных, а также другие новые функции.

Другие форматы файлов Офиса, такие как Visio и Entourage (Mac), остаются теми же.

Форматы документов Microsoft Word — от старого DOC до нового DOCX

Документ Microsoft Word представляет собой файл с расширением doc или docx. До 90-х годов XX века расширение doc использовалось для текстовых файлов, которые не содержат разметки. И сейчас можно убедиться, что файл такого типа легко создать с помощью, например, программы «Блокнот». Правда, он не будет иметь богатого форматирования, но легко открывается программой Ворд, в которой набранному в блокноте тексту можно придать более оформленный вид. Когда корпорация Майкрософт выпустила программу Ворд, разработчики решили использовать в ней расширение doc. К настоящему времени этот текстовый редактор является самым популярным в мире, поэтому файл с расширением doc ассоциируют с этим программным продуктом и называют просто «вордовский формат».

Что такое формат?

Старый формат DOC отличался сложным содержанием, и нормально читался только в MS Office

В отличие от других текстовых форматов этого же производителя, например, RTF (Rich Text Format File), внутреннее содержание doc более сложное и запутанное. В формате Word сохраняется не только символьная информация, но и различные объекты (например, схемы, диаграммы, формулы, сценарии). Разработчики используют закрытый код, в котором посторонний разобраться не сможет. Чтобы увидеть «внутренности», файл можно открыть, например, в блокноте. В RTF любопытствующий увидит стройные ряды данных, похожие на содержание кода интернет-страниц. Во втором случае — пугающую кашу из знаков самого разнообразного происхождения и вида. В отличие от зашифрованного документа Word, файл RTF не содержит непечатных бинарных символов, легко открывается во всех текстовых и даже графических редакторах. В то же время практически ни одна программа (кроме соответствующего продукта от компании Майкрософт) не обладает способностью адекватно открыть для просмотра и редактирования документ Word. Сейчас офисный пакет этой компании очень широко распространен и доступен любому пользователю.

Современные форматы «вордовских» документов

Даже бесплатные современные редакторы документов умеют корректно работать с DOCX

Кроме того, сложности могут возникнуть даже при использовании разных версий офисного пакета Майкрософт. Дело в том, что начиная с версии Word 2007 года документ по умолчанию сохраняется с расширением не doc, а docx. Поэтому если установлен пакет офиса, выпущенный ранее, то необходима конвертация для устаревших версий. Конверторы для обеспечения совместимости предлагаются самой компанией Майкрософт (Microsoft Office Compatibility Pack), так что обычно при открытии docx, например, в версии Ворд 2003, сложностей не возникает, но при этом может потеряться часть данных форматирования и возможностей редактирования.

Компания Майкрософт была вынуждена пойти на изменение формата Word под давлением международных организаций, которые требовали подвести его под какие-либо стандарты. Был выбран вариант, основанный на языке разметки XML, который часто используется в документах интернет. Документ с расширением docx имеет некоторые преимущества перед устаревшим форматом, в частности, меньший вес, что имеет значение при передаче документа через интернет. Поэтому при ограниченных скоростях передачи данных пользователям имеет смысл использовать более современный формат Word.

Microsoft created and released the spreadsheet program known as Excel. It comes from the Microsoft Office family of productivity programs. Excel groups data into columns and rows as opposed to a word processor like Microsoft Word. A cell is a location where rows and columns cross. Data, such as text, a number, or a formula, are contained in each cell. They might not be able to display every feature of a file, programs that are compatible with a file format can present an overview of a file. When we want to save our files, we will have numerous file formats including Excel workbooks, templates, etc. These file formats are divided into various types, including Excel, Word, and PowerPoint presentations.

File formats in Excel are of various types, but to determine how many formats exist in Excel, we must follow the procedure outlined below: 

Step 1: Click on the file option at the top of the ribbon.

Step 2: Select the Save As option. The Workbook can be saved on local devices (like a computer) and the internet (e.g. OneDrive).

Step 3: Click on the option Browse and save as the dialog box opens. 

Step 4: Choose the Save As option and you will see a list of file formats. Depending on the type of active Worksheet in your Workbook, several file types will be displayed (Data Worksheet, Chart Worksheet, or another type of Worksheet).

Step 5: Select the desired file format by clicking.

Excel File Formats

Excel Workbook

Extension: .xlsx

Spreadsheet files were created using Excel version 2007 and later have this extension. Currently, the default file extension for Excel files is XLSX. XML is the foundation of the file format XSLX. With the aid of this technology, XSLX files are significantly lighter and smaller than XLS files, which immediately results in space savings. Excel documents may be downloaded or uploaded more quickly. The only drawback of this XSLX extension is that it cannot open files created before Excel 2007.

Excel Macro-Enabled Workbook

Extension: .xlsm

With Excel 2007 and later, including Excel macros, the spreadsheet produces files with this suffix. It’s simple to deduce that a file contains a macro with the aid of an extension. This version was created for security purposes to prevent computer viruses, harmful macros, infecting machines, etc. from accessing a file. When it comes to security and macros, this file extension is quite dependable.

Excel Binary Workbook

Extension: .xlsb

When it comes to compressing, storing, opening, etc., this file extension type completely supports excel files that include a lot of data or information. It takes a lot of time to open and process an excel file with a lot of data. It occasionally hangs while opening and regularly crashes.

Template

Extension: .xltx

A template made by the spreadsheet program Microsoft Excel, part of the Microsoft Office family, is known as an XLTX file. It has predetermined layout options that may be used to produce several Excel spreadsheets (typically.XLSX files) with the same formatting and characteristics. XLTX files that give you a head start when making spreadsheets like bills, calendars, and budget plans. Additionally, you may make unique templates using your spreadsheets.

Template (code)

Extension: .xltm

A Microsoft Excel spreadsheet template with macro support is known as an XLTM file. It may also keep settings, spreadsheet data, and information about the layout in addition to one or more macros. When looking to generate several spreadsheets (primarily. XLSM) with the same data and style, Excel users save spreadsheets as XLTM files.
XLTX files and XLTM files are related. XLTM files, on the other hand, enable macros, which are collections of instructions that a user has organized so they may swiftly carry out a time-consuming or difficult operation, including formatting a document, inputting data, or conducting computations.

Excel Add-In

Extension: .xlam

The spreadsheet program Microsoft Excel, part of the Microsoft Office family, uses XLAM files, and add-ins that support macros. It is used in Excel to add new features and instructions. While some XLAM files are produced by Microsoft, others are produced by Excel users and third-party developers. Microsoft Excel users can add more features since different users use the program for various, specialized purposes. Users must install an XLAM file-based Excel add-in to add this functionality.

XML Spreadsheet 2003

Extension: .xml

A plain text document is an XML file, and to distinguish them, they are saved with the.xml file extension. The XML file format was created to convey data over the internet and can hold hundreds of entries in the computation. Either humans or machines can read it.. The majority of programming languages make use of XML libraries to do the parsing. Down-converting is the process of converting XML files to other required forms.

XML Data

Extension: .xml

Other description languages like RSS, DOCX format, XSL, and Microsoft don’t employ XML as a format. The text editor notepad++ can open this XML file natively. We need to have a few interactions with the various file organizations to manage the different file formats. The only organization that is required for data and web pages is XML. Next, you could double-click the browser—the file’s default viewer—on occasion to examine a file.

Microsoft Excel 5.0/95 Workbook

Extension: .xls

A spreadsheet file, known as an XLS file, can be produced by Microsoft Excel or exported by another spreadsheet application, like OpenOffice Calc or Apple Numbers. It includes one or more worksheets that store and present data as tables. The Microsoft Excel Spreadsheet (XLS) binary format was introduced together with the initial 1987 version of Excel. Up to the introduction of Excel 2007, XLS files became one of the most used file formats for preserving spreadsheets. Microsoft replaced XLS files with the Microsoft Excel Open XML Spreadsheet (XLSX) format with this version. Excel spreadsheets are often saved in XLSX files.

Excel 4.0 Workbook

Extension: .xlw

Workspace files, which are saved in the well-known spreadsheet program Microsoft Excel, have the .xlw file extension. Workbook file references and screen locations are stored in files with the .xlw extension. When .xlw files are opened, the program can move them back to the spot on the screen where they were stored. .xlw files are essential for restoring layouts when a user is working on many workbooks at once. .xlw files only refer to workbook layouts on the screen, therefore they should not be mistaken for files that contain workbook data. These files are primarily utilized by Microsoft Excel 2010 and 2011, and users need to have all workbook files to correctly reopen these files.

Works 6.0-9.0 spreadsheet

Extension: .xlr

The file format specifications for XLR files were not made publicly available and were instead kept as binary files. Developers are consequently unable to examine the file system and create programs that read from and write to these files programmatically. The Works Spreadsheet saves data to.xlr files using the same Excel file format.

Text File Formats

Formatted Text (Space-delimited)

Extension: .prn

A PRN file is one that was made using the Print to File checkbox that may be found in several Windows Print dialogue boxes. A printer, fax machine, or other device utilizes it to print a document because it contains a set of device-specific instructions. Depending on the device the file was produced for, PRN files may include text or binary information.

Text (Tab-delimited)

Extension: .txt

An ordinary text document with simple text is known as a TXT file. Any text-editing or word-processing application may open and edit it. The most widely used text editors for producing TXT files are Apple TextEdit and Microsoft Notepad, which come pre-installed with Windows and macOS, respectively. TXT files are plain text files with very little to no formatting. They are utilized to manage manuscripts, detailed instructions, notes, and other text-based information.
When a user of TextEdit saves a document as a TXT file, those applications remove the document’s formatting (bolding, italicization, font style, alignment, etc.). Most users don’t store more complex text documents, including flyers, reports, letters, or resumes, as TXT files. Instead, they save them as other types of files.

Text (Macintosh)

Extension: .txt

This function guarantees that tab characters, line breaks, and other characters are properly understood when a workbook is saved as a tab-delimited text file for usage on the Macintosh operating system. only saves the active sheet.

Text (MS-DOS)

Extension: .txt

Ensures that tab characters, line breaks, and other characters are properly understood when saving a workbook as a tab-delimited text file for use on the MS-DOS operating system. only saves the active sheet.

DIF

Extension: .dif

Data interchange format, or DIF for short, is a widely accepted standard for exporting spreadsheets. Users can export data from a spreadsheet in a format that can be loaded by several other programs using DIF files. The format has the drawback of not supporting numerous spreadsheets. This indicates that just one spreadsheet may be stored in a DIF file. As a result, you will need to make numerous DIF files if you wish to export many spreadsheets in the DIF format.

Unicode Text

Extension: .txt

The workbook can be saved as Unicode text, a character encoding standard created by the Unicode Consortium.

SYLK

Extension: .slk

A file stored in the Symbolic Link (SYLK) format, developed by Microsoft to transmit data between spreadsheet applications and other databases, is referred to as an SLK file. It has semicolons between lines of text that describe the cell row, column, layout, and content. An ANSI text file format is used to hold SLK files. SYLK (Symbolic Link) codes, such “E,” which stands for an expression within a cell, are used to record complex formulae.

CSV (comma delimited)

Extension: .csv

The Comma Separated Value (CSV) file extension is frequently used to identify files in this format. An easy text format for a database table is a comma-separated values file. A row in the table is represented by one line in the CSV file. Fields from different table columns are separated inside the line by commas. The CSV file format is straightforward and is accepted by a wide range of software. Moving tabular data between two separate computer applications sometimes involves the usage of csv files.

CSV (Macintosh)

Extension: .csv

Ensures that tab characters, line breaks, and other characters are properly understood when saving a workbook as a comma-delimited text file for usage on the Macintosh operating system. Only saves the active sheet.

CSV (MS-DOS)

Extension: .csv

Ensures that tab characters, line breaks, and other characters are properly understood when saving a workbook as a comma-delimited text file for use on the MS-DOS operating system. only saves the active sheet.

Other File Formats

PDF

Extension: .pdf

Format for Portable Documents (PDF). This file format allows file sharing and maintains document layout. The format that you intended is kept when the PDF file is printed or read online. The file’s data cannot be readily altered. For papers that will be printed using professional printing techniques, the PDF format is also beneficial. Note: Excel 2007 does not support this format.

Open document spreadsheet

Extension: .ods

The spreadsheet in OpenDocument. You can save Excel 2010 files so they can be opened in spreadsheet software like Google Docs and OpenOffice.org Calc which supports the OpenDocument Spreadsheet format. Additionally, Excel 2010 supports opening spreadsheets in the. ods format. When. ods, files are opened and saved, and formatting could be lost.

DBF 3, DBF 4

Extension: .dbf

The database management system program dBASE uses a standard database file called a DBF. It divides the information into several records with fields kept in an array data type. Due to the ubiquity of the file format, other “xBase” database tools are also compatible with DBF files. DBF files have been extensively embraced as a standard storage format for structured data in business applications due to their early adoption in the database community and a very simple file layout.

XPS Document

Extension: .xps

XML paper specification files are the ones with the .XPS suffix. These files have a predefined layout and are used to safeguard the accuracy of the data they contain. The sole distinction between them and the well-known PDF file format is the .XPS format’s usage of XML standards for its file structure. The data in your file may be read, shared, and modified using XPS files, which are simple to distribute online. It has become a well-liked substitute for the PDF file format as a result. Any software that runs on Windows and has printing capabilities may produce XPS files.

Microsoft Office Compatibility Pack makes files created with Office 2007 and later work seamlessly on earlier versions of Office. If you’re using an unpatched version of Office, this download will fix it. However, before you install this pack, make sure to download and install all of the latest updates from Microsoft.

If you’re still using Office 2000, Office XP, or Office 2003, then this patch will help you easily open, edit, and save files created with newer versions of Office. It’s a surprisingly big download — checking in at 37MB. That means you should set aside some time to download it if you’re on a slow connection. Once you install this pack, you don’t have to do much to make it work. It automatically repairs the issue. It also adds support to the Word Viewer 2003, Excel Viewer 2003, and PowerPoint Viewer 2003 to open DOCX, XSLX, and PPTX files.

While it’s surprising that Microsoft Office Compatibility pack is as big as it is, it’s not loaded down with unnecessary extras, and it solves compatibility issues with older versions with little effort on your part.
