The .XLB file extension, also known as the Excel Toolbars File, is a file format for storing configuration settings utilized in Microsoft’s popular spreadsheet software package, Microsoft Excel. This file contains information on all the application’s toolbar layouts, such as the information used to create and view different toolbars, and their respective positions within the Microsoft Excel interface.
Technical details
The .XLB file type is classified as a data file by Microsoft Corporation and is associated with the Excel application. This format is comprised of binary data and usually appears in a compressed form when opened with a text editor. To modify or read an .XLB file, it must be opened within its associated program; external programs are not compatible with this type of file. Additionally, these files can be seen as backups in the event of a program shutdown or corrupt setting.

Other associated Microsoft Office file extensions include: .XLW, .XLA, .XLL, and .XLM.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .XLB) 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 .XLB 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 .XLB 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 .XLB 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 .XLB extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .XLB file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .XLB 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 .XLB file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .XLB file) will be extended to the maximum.
It is also good to check
- if the .XLB file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
