How to convert XLSB to XLSM
- Add your .XLSB file - drop it in the box above or click to browse.
- Convert it to .XLSM in a few seconds.
- Download your new .XLSM file.
What to expect
XLSMfiles are typically larger thanXLSBbecause XML text is less compact than binary storage.- VBA macros carry over intact; if the workbook has no macros, saving as
.xlsxgives even broader compatibility. - If macro fidelity is critical, use Excel for the conversion - LibreOffice preserves the macro code in the file but may not execute all VBA correctly.
Frequently asked questions
Are VBA macros preserved when converting XLSB to XLSM?
Yes. Both
XLSB and XLSM store VBA macros in an embedded vbaProject.bin block, so the macro code carries over intact. If you convert via LibreOffice, the macros are kept in the file - opening the result in Excel will run them normally.Will formulas and pivot tables survive the conversion?
Yes.
XLSB and XLSM support the same formulas, pivot tables, charts, and formatting, so converting in Excel or LibreOffice is lossless for standard workbook content.Why not convert to XLSX instead of XLSM?
If the workbook contains VBA macros, saving as
.xlsx will drop them - Excel warns about this and requires you to choose XLSM to keep them. Use .xlsx only if you want a macro-free copy.Why is the XLSM file larger than the original XLSB?
XLSB stores data as compact binary records, while XLSM uses XML text inside a ZIP archive - the same data takes more space in XML form.Programs that convert XLSB: Microsoft Excel · Microsoft Excel for Mac · Apache OpenOffice Calc (OpenOffice.org Calc) · LibreOffice Calc
