Free Excel to Markdown converter

What happens with multiple sheets?
Each visible sheet becomes its own ## Sheet name section with a table. Hidden sheets are skipped, and empty columns are removed.
Do formulas work?
Yes. The calculated value saved in the file is used (for example =C2*D2 becomes 28.5). Dates are written as ISO dates like 2026-09-01.
Is my spreadsheet uploaded?
No. It is read by your browser using the open-source ExcelJS library and never leaves your computer.
