You can save an Excel file in another file format by clicking the File > Save As. The file formats that are available in the Save As dialog box vary, depending on what type of sheet is active (a worksheet, chart sheet, or other type of sheet).
Note: Whenever you save a file in another file format, some of its formatting, data, and features might not be transferred.
To open a file that was created in another file format, either in an earlier version of Excel or in another program, click File > Open. If you open an Excel 97-2003 workbook, it automatically opens in Compatibility Mode. To take advantage of the new features of Excel 2010, you can save the workbook to an Excel 2010 file format. However, you also have the option to continue to work in Compatibility Mode, which retains the original file format for backward compatibility.

Файл Excel можно сохранить в другом формате, щелкнув файл > Сохранить как. Форматы файлов, доступные в диалоговом окне Сохранить как, зависят от типа активного листа (листа, листа диаграммы или другого типа листа).
Примечание: Когда вы сохраняете файл в другом формате, часть форматирования, данных и функций может быть потеряна.
Чтобы открыть файл, созданный в другом формате (в более ранней версии Excel или в другой программе), выберите файл > Открыть. Если открыть книгу Excel 97–2003, она автоматически откроется в режиме совместимости. Чтобы воспользоваться новыми возможностями Excel 2010, сохраните книгу в формате Excel 2010 файла. Однако вы также можете продолжать работать в режиме совместимости, при этом исходный формат файла сохраняется для обратной совместимости.

Extensions of Excel
Excel is one the tool which has a variety of extension in which we can save the file. A commonly used extension in Excel is .xlsx, which is used for storing a simple type of data. XLS is another type of default extension which was used until MS Office 2007. For storing a VBA code, we have XLSM. This is purely made for macros. Another extension, CSV (Comma Separated Values), delimits the data, which is separated by commas. XLSB extension is used for compression, saving, opening etc.
For example, the filename “XYZ.doc” has an extension of “.doc, ” a file extension associated with the document file.
Excel file extensions can be of various types. Here we will cover the most common file type:
- XLS – Excel file extension
This extension is the most common and default type in the spreadsheet generated by Microsoft office. Prior to Excel 2007, the file extension was XLS. This extension refers to a file which contains all type of information including data, formats, graphics etc. The operating system recognizes the file type with the help of an extension and operates this file using the Excel application.
The XLS is the default file type for Excel version 2.0 to Excel 2003.
- XLSX – Excel file extension
This extension is used by the spreadsheet files generated with the Excel version 2007 onwards. For an Excel file, the current default file extension is XLSX.
XSLX is an XML based file format. With the use of this technology, the file with XSLX format is very less in weight or size, and as compared to the XLS file format, this leads directly to saving space. It requires less time to download or upload excel documents.
Only one disadvantage of this XSLX extension is that this version is incompatible to run the files prior to Excel 2007.
- XLSM – Excel file extension
This extension file type is generated by the spreadsheet with the excel version 2007 onwards, including Excel macros.
With the help of an extension, it’s easy to understand that the file contains a macro. Because of security reasons and for protecting a file with computer viruses, malicious macros, infecting computers, etc., this version comes into existence.
This file extension is very reliable in terms of macros and for security reasons.
- XLSB – Excel file extension
If excel files contain a large amount of data or information, this file extension type fully supports in the compression process, saving, opening, etc.
An excel file that contains a large amount of data takes a lot of time in the opening in processing that file. Sometimes while opening, it gets hanged and frequently crashes.

Probably 99% of all Excel workbooks are saved in the XLSX file type these days. But there are various other file extensions available: For example XLSM, XLSB or “older” Excel users might still remember the XLS file type. What are the differences of these file types? And even more important: Which one should you use?
When you save an Excel workbook for the first time or use the “Save As” function, you are asked for a folder, file name as well as the file type. By default, Excel suggests the XLSX file type (unless your file has VBA macros). The window looks similar to the screenshot on the right side.
So which file type are you going to use? The answer – like so often: It depends. Before we conclude in a decision tree, we we take a look at the most important file extensions in Excel with their advantages and disadvantages first.
XLSX
The “default” file extension is XLSX. The large majority of Excel workbooks uses this format these days. Microsoft says in the Excel help text about the XLSX file format:
The default XML-based file format for Excel 2007-2013. Cannot store Microsoft Visual Basic for Applications (VBA) macro code […].
Most of the time you use the XLSX format: It’s save (can’t store malicious code), has the maximum number of rows and columns and is best known. XLSX is available since Excel 2007 and replaces the old XLS file type. It uses the open XML standard so which is documented well.
Knowing these quick facts, there are the following advantages and disadvantages for the XLSX file format:
| Advantages | Disadvantages |
|---|---|
|
|
XLS
The XLS file type has been the default Excel file extension and format before Excel 2007. In Excel 2007, XLSX replaced the XLS format. Therefore, XLS is kind of outdated right now. In the daily life you won’t find it often any more. But some data base tools still export data as XLS files.
The XLS file type has some disadvantages towards the newer file types XLSX or XLSM: It’s rather unsafe as it can contain VBA macros with malicious code. Also, it needs more disk space than the other file types and at the same time has less rows and columns.
On the other side the only advantage: You can easily open XLS files with older versions of Excel.
| Advantages | Disadvantages |

XLSM
If you include VBA macros in your XLSX file, you will be asked to change the file extension to XLSM. Only that way you can save your macro within the Excel file (there are other file types possible, e.g. XLSB – but you can’t use XLSX for VBA macros). Therefore, it has most of the advantages and disadvantages of the XLSX file type. Positive: You can immediately identify Excel files with VBA macros.
| Advantages | Disadvantages |

XLSB
Many people don’t know that there is an actual alternative to the XLSX and XLSM file type: The XLSB file extension. XLSB files store the data a little bit different than the XLSX or XLSM file types: They don’t use the XLM file structure. Instead, XLSB files try to save disk space because the data is stored in the binary structure. The main difference: Binary files are computer- but not human-readable. For more information on binary files in general, please refer to this Wikipedia entry.
The main disadvantage: Binary Excel files can contain VBA macros. So unless you don’t know the origin of a file, please consider well before opening them. Besides that: All the other disadvantages seem minor.

CSV
CSV stands for comma separated values. These files are basically plain text – so there are no formulas or formatting. CSV is often used for data exchange. Excel provides the functionality to import or even directly open CSV files.
The basic application for CSV files: Import or export data. Data base programs often export data as CSV files. Also if you want to transport Excel data into a database program, often the CSV file type works.
| Advantages | Disadvantages |
|---|---|
|
|
ODS
ODS stands for Open Document Spreadsheet. The file type is designed to work on both Excel and other applications, e.g. LibreOffice. From the Excel point of view, ODS doesn’t support all the features. Text and data is usually saved well though. But formatting and many other features (for example charts, tables, conditional formatting) might run into problems.
| Advantages | Disadvantages |
|---|---|
|

XLSX (Strict)
Besides the regular XLSX format, Excel offers to save your Excel workbook as “Strict Open XML Spreadsheet”. So what is the difference between those two? Basically, the two file types use the same structure. But:
The Strict variant has less support for backwards compatibility when converting documents from older formats.
Furthermore:
The Strict variant of XLSX disallows a variety of elements and attributes that are permitted in the more common Transitional variant […]

As you’ve probably heard of PDF files, we won’t go much into detail here. PDF stands for portable document format and has the reputation of not easily being manipulated. Also, it’s quite save to say that how a PDF file looks on your computer, it will most probably look like this on most other computers.
And that’s it for the advantages. I recommend using it when you present your final results in the following cases:
- The recipient of your file should not edit it any more.
- Formatting should be exactly preserved.
- There is no database included, just the summarized results.
That could be the case if somebody wants to check your results on an iPad or a similar device. But: In many cases it would be professional (and nice) to also send at least parts of your Excel file. That way, your recipient could at least take a look at the calculation process.

XLAM
XLAM is the file extension for Excel add-ins. Also our add-ins (for example the popular “Professor Excel Tools“) are XLAM files. They can contain VBA macros, worksheets as well as forms, images and individual ribbons. If you double click on such file, it will open in Excel and you can use the funcationality of the add-in. But next time you open Excel again, it won’t be available any longer. You rather have to enable the add-in within the options (File –> Options –> Add-Ins).
As the XLAM file type is not really an alternative for all the other file extensions above, we skip the advantages and disadvantages.
Comparison of file types
So if we put all the advantages, disadvantages and facts from above together, we come to the following comparison:
Which file type should you use?
Decision Tree
In order to define the best file type for your Excel workbook, please follow the decision tree.
- The first question: Do you just want to display your results only? Then you could also consider the PDF format. But if the recipient of your work wants to edit or follow up your calculations, you shouldn’t use PDF.
- Does your file contain VBA macros?
- If yes, choose XLSB if you have a large file. Choose XLSM for a file size smaller than app. 10 MB.
- If no and you got a large file (larger than app. 10 MB), also choose XLSB.
- If no (you don’t have macros) and your file small, follow the tree on the right hand side.
- The lower two levels of the decision tree are just about compatibility: If you want to open and edit your workbook with another software, choose the strict XLSX or ODF format.
- If you want to make sure that you can open it with versions of Excel 2003 or earlier, go for XLS.
Summary
In conclusion, you can distill a quite short table (if you don’t need to consider old file types and other applications as LibreOffice). You just have to answer two questions: Do you need VBA macros and do you work with a large amount of data?
