About Compress XLSX
Reduce Excel file size by stripping unused styles, defined names, and embedded image bloat. Calculations and pivot tables are preserved.
Frequently asked questions
Will formulas still work after compression?
Yes. Only metadata and embedded media are touched; cells and formulas stay byte-identical.
Why is my .xlsm rejected?
Macros (VBA) can be sensitive to file rewriting; we only support macro-free .xlsx.
