What is the .XLB File Extension?


.XLB File Extension Description:

The file extension XLB is used by the application Microsoft Excel; one of the applications in the office suite Microsoft Office. This XLB file extension, however, is not the file extension used for the created spreadsheets in Microsoft Excel. It is the file extension used for saved Microsoft Excel customized toolbars.

The toolbar in Microsoft Excel consists of a lot of different icons, each having its own purpose and function. It could be for formatting data in a cell or the whole spreadsheet; it could be for arranging data in cells alphabetically; etc. The arrangement of these icons was pre-made by the developer of Microsoft Excel.

Often, users change the format and the look of the toolbar. Some do it for aesthetic purposes, but most do it for functionality. When a user customizes his Microsoft Excel toolbar to his liking, a file with the file extension .xlb is created. This created file is, by nature, hidden.

Every version of Microsoft Excel creates different filenames for the saved customized toolbar. The files with the file extension .xlb could be any of the following: Excel5.xlb, Excel8.xlb, Excel.xlb, Excel10.xlb and Excel 11.xlb. These are the files created by MS Excel when saving customized toolbars for the versions Excel 95, Excel 97, Excel 2000, Excel 2002, and Excel 2003 respectively. There are instances, though, that Microsoft Excel will apply the username of the logged in user as the filename, plus the file extension XLB. The format will look like "username.xlb."

A good thing about the files with the file extension .xlb is that they are portable. Once the .xlb file format is already visible, the user can copy it to a disk or any medium of storage. When the file is copied to another computer, Microsoft Excel will instantly employ the user's customized MS Excel toolbar. This will only work if the version of MS Excel on the 2nd computer is the same as the source of the file with the .xlb file extension.
