Convert Excel sheets to Markdown tables.
Every sheet becomes a titled section with a proper Markdown table. Runs locally in your browser.
Your files are never stored: documents convert in your browser where possible, and anything sent to our AI travels encrypted (HTTPS) and is discarded after processing. Privacy Policy
Spreadsheets pasted into documents usually turn into unreadable tab-separated mush. CleanMD emits real Markdown tables with aligned columns, one section per sheet, using the sheet name as the heading — ready for GitHub, Obsidian or Notion. The conversion is fully client-side.

Frequently asked questions
How are multiple sheets handled?
Each sheet becomes its own section: the sheet name is the heading and the cells below it become a Markdown table.
Are formulas converted?
The computed values are exported, not the formulas — which is what you want in a document.
Is my spreadsheet uploaded?
No. XLSX conversion runs entirely in your browser; the file never leaves your device.
What about very wide tables?
Wide tables are exported in full. Markdown renderers scroll them horizontally, so no data is lost.
