- Description
- The xlsb file type is a binary file format used to store Excel spreadsheets. It is a compressed version of the xlsx file type and can only be opened in the Microsoft Excel application. Compared to the xlsx, the xlsb format is much smaller in size and is less prone to corruption.
- XLK files are Microsoft Excel Backup Files, which are created as backup copies of Excel files (.XLS or .XLSX). They contain a copy of the excel file in its original state, and can help to restore a file if the original is lost, damaged or corrupted.
