Markdown Tables for GitHub, Docs & LLMs
Markdown tables render natively on GitHub, GitLab, Notion, Obsidian, and every major docs framework, and they are the cleanest way to hand tabular data to ChatGPT or Claude. Converting Excel to Markdown locally means even sensitive spreadsheets (budgets, client lists, internal metrics) can be shared as plain-text tables without the file ever touching a third-party server.

Frequently Asked Questions
How do I convert an Excel file to a Markdown table for free?
Drop your .xls, .xlsx, or CSV file into the converter above. Each sheet becomes a clean GitHub-Flavored Markdown table right in your browser. Preview the result, copy it, or download a .md file. Completely free, no signup, no watermarks.
Is my spreadsheet uploaded to a server?
No. Conversion runs 100% locally in your browser using open-source WebAssembly. Nothing is uploaded, stored, or logged, so financial models, client data, and internal reports stay private on your device.
Which spreadsheet formats are supported?
Excel formats .xls, .xlsx, .xlsm, and .xlsb, the OpenDocument spreadsheet format .ods, and plain CSV files. The format is detected from the file content, so mislabeled files still convert.
Can I convert CSV to a Markdown table?
Yes. CSV files convert directly to GitHub-Flavored Markdown tables that render in GitHub issues, pull requests, READMEs, Notion, Obsidian, and docs sites. There is even a demo CSV button in the converter to try it instantly.
Can I convert Google Sheets to Markdown?
Yes, in two steps: in Google Sheets choose File → Download → Microsoft Excel (.xlsx) or Comma Separated Values (.csv), then drop the downloaded file here. The sheet becomes a Markdown table without your data leaving the device.
What happens to formulas, formatting, and multiple sheets?
Cell values are exported, so formulas are converted to their computed results. Visual formatting like colors and borders does not exist in Markdown and is dropped. Workbooks with multiple sheets convert each sheet into its own Markdown table.
Why convert Excel tables to Markdown?
Markdown tables are plain text: they render on GitHub, work in READMEs and documentation, diff cleanly in version control, and are easy for LLMs like ChatGPT and Claude to parse. Converting XLSX or CSV to Markdown is the fastest way to get tabular data into a prompt or a docs page.
Is there a file size limit?
Files up to 40 MB are accepted. Very large spreadsheets may use more memory because conversion happens on your device; extremely wide tables also become hard to read in Markdown form.
