Why does the Binary Format (XLSB) Reduce Excel File Sizes?

The Excel Binary Workbook format is a proprietary Microsoft Excel format that compresses and reduces Excel file size with no data loss. An Excel file saved as a Binary Workbook (“.xlsb extension) can be significantly smaller than the one saved as an Excel Workbook (.xlsx or .xlsm or other Excel extensions).

It’s probably the fastest and most straightforward way to reduce Excel file size. The icing on the cake is that a file saved under the Excel Binary Format can contain Excel Macros.

  5.  “Save”.

You can now quit Excel with a much lighter file. The reduction in the Excel file size can be pretty impressive for a large Excel file.

What Is the Downside of the Excel Binary Workbook (XLSB Format)?

Various 3rd party software, some budgeting software, for instance, cannot read/write XLSB files if you have to upload them into the application: you will have to save your file with the XLSX or XLSXM extension temporarily.
