Convert XLM to XLSM

QUICK ANSWER
Is it possible to convert XLM to XLSM?
Yes - XLM converts to XLSM.

The right modernization path: open the .xlm in Excel and re-save as a macro-enabled workbook (.xlsm). XLM macros do not auto-translate to VBA - you must rewrite the logic in VBA (or Office Scripts). Save as .xlsm only if the automation is trusted.

Also to XLSM: XLSB · XLTM · XLAM
