Convert Excel XLSX sheets to Markdown tables
Convert visible Excel worksheets into readable GitHub-flavored Markdown tables entirely in your browser.
The converter reads the XLSX package directly, keeps worksheet order, resolves shared text values, leaves blank cells blank, and excludes hidden sheets by default.
Local browser processing. No document upload.

Questions about XLSX
Are hidden worksheets converted?
No. Hidden worksheets are excluded by default to avoid exposing unintended content.
Does it calculate formulas?
No. It reads cached workbook values and does not execute spreadsheet formulas.
