Microsoft Excel 2007/2010 Binary Workbook Format | Microsoft | Spreadsheet Files |
The XLSB (Excel Binary Spreadsheet) file extension, as defined by the Microsoft Office Excel application, is used in its popular spreadsheet and data-organizing software. It is a binary file format, created to store .XLSX files in a more efficient manner than the default XML format, and has been supported from version 2007 onwards.
XLSB files are more compact than their XML counterparts, thus providing for better performance. This is particularly advantageous when dealing with larger spreadsheets or multiple sheets within a workbook. Although each XLSB file has limited support for multimedia components such as embedded audio and video, which are not accessible on certain machines, it does provide good data organization and calculations support.
Similar File Extensions
XLSB shares similarity with other Excel compatible spreadsheet formats such as .XLS, .XLSX, and .XLSM. All of these formats can be opened and edited using Excel applications that run on all supported platforms such as Windows, macOS, iOS, and Android.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .XLSB) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .XLSB extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .XLSB file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .XLSB extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .XLSB extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .XLSB file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .XLSB file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .XLSB file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .XLSB file) will be extended to the maximum.
It is also good to check
- if the .XLSB file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
