What is an XLB file

XLB files mostly belong to Excel by Microsoft. XLB is the file format used by an Excel toolbar. Excel is a spreadsheet software developed by Microsoft. It is a part of the Microsoft Office suite of productivity software. The XLB file stores custom configurations for the toolbars and menus in Excel. Custom configurations mean that commands can be added to the toolbar according to the preferences of the user. XLB is a binary format file and is typically located in the \Users\username\AppData\Roaming\Microsoft\Excel directory. XLB files are used to store manual customizations of toolbars in older versions of Excel, but newer versions of Excel use the EXPORTEDUI format to store customizations for the ribbon and Quick Access Toolbar. However, the XLB file is still used by Excel and may store customizations made by macros. Common file names for the XLB file are Excel.XLB, Excel5.XLB, Excel8.XLB, Excel10.XLB, Excel11.XLB, Excel12.XLB, and Excel15.XLB. The file name Administrator.XLB is used by Excel in Windows NT.

XLB file format details:

The file format determines how the data is stored in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. If there are problems opening a file, you must first determine the file format used. Our analysis of the XLB files produces the following result:

XLB files can be up to 8 MB in size, but are often around 10 KB - 12 KB. This file type is based on cutting-edge technology. Excel15.xlb or Excel12.xlb is a typical file name.
