Why do file converters destroy VBA macros?

Every major file conversion service — Smallpdf, Zamzar, ILovePDF, CloudConvert — runs files through sandboxed infrastructure. Macros are executable code, and allowing arbitrary VBA to run server-side is a security risk they're not willing to take. So they strip them silently.

The result: you upload an .xlsm with 3,000 lines of automation logic, convert it to .xlsx, and get back a spreadsheet that opens without errors — but all your macros are gone. No warning. No error message. Just silence.

Which file types are affected?

  • .xlsm — Excel Macro-Enabled Workbook (VBA modules)
  • .docm — Word Macro-Enabled Document (VBA + field codes)
  • .xlam — Excel Add-In (macro libraries)
  • .dotm — Word Macro-Enabled Template
  • .pptm — PowerPoint Macro-Enabled Presentation

What searches lead people here?

Most people searching "xlsm to pdf keep macros" or "excel macro converter" don't realize macros can't survive a PDF conversion — PDF is a static format. What they actually need is xlsm → xlsx with macros preserved, or a way to audit what would be lost before converting.

This tool lets you see exactly what's at risk before you commit to a conversion pipeline.
