XLSunprotect

XLSunprotect is a commandline tool written in go to remove the workbook and worksheet protection from Excel files (.xlsx). It is powered by excelize.

Powered by go, it is compiled and statically linked to a single binary. It does not have any dependencies (Python, JRE, bash, ...). Just distribute the .exe file.

• The results are written to <filename>_unprotected.xlsx in the same folder
• The original file remains unchanged
