Convert Excel sheets to Markdown tables.
Every sheet becomes a titled section with a proper Markdown table. Runs locally in your browser.
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.
