How to Convert Excel to Markdown Online

  1. Drop one or more .xlsx or .xlsm workbooks — everything is processed locally and never uploaded.
  2. Click Convert to Markdown — every worksheet is turned into a GitHub-Flavored Markdown table.
  3. Check the preview — each result row shows the converted Markdown text before you download.
  4. Download the .md file — a single file downloads directly; multiple files come back as a ZIP.

What Happens to Each Sheet

Each worksheet is exported as a "## SheetName" heading followed by a GFM pipe table: the first row becomes the header, the second row is the | --- | separator, and every remaining row follows as table data. A completely empty sheet is emitted as a heading plus the placeholder marker, so the document structure stays predictable.

Pipes inside cells are escaped as \| and line breaks become <br>, so even cells full of special characters cannot break the table structure.

Limitations

  • .xlsx and .xlsm only — convert legacy .xls files to the new format first.
  • Styles, colors, merged cells and charts have no Markdown equivalent and are dropped.
  • Each sheet becomes its own table; extremely wide sheets stay valid but are hard to read.
  • Dates are exported as text values in the displayed format.

Frequently Asked Questions

Is this Excel to Markdown converter free?

Yes — 100% free with no sign-up, no watermark and no file limit. All conversion happens in your browser.

Which Markdown flavor does it produce?

GitHub-Flavored Markdown (GFM) pipe tables. They render on GitHub, GitLab, Notion, Obsidian, VuePress and virtually every Markdown engine that supports tables.

What happens to cells containing the | character?

The pipe is escaped as \|, which is exactly how GFM represents a literal pipe inside a table cell, so your column layout stays intact.

How are line breaks inside cells handled?

Each line break is replaced with the <br> tag, the standard way to keep multi-line content inside one Markdown table cell.

Are formulas converted?

Formulas are exported as their last calculated values — Markdown has no formula concept.

Will my file be uploaded to a server?

No. The workbook is opened, converted and previewed entirely in your browser with JavaScript. Your file never leaves your device.

Can I convert several workbooks at once?

Yes. Drop multiple files and download the .md results together as a single ZIP archive.

How do I use the output in Notion or GitHub?

Open the downloaded .md file, copy the table block and paste it. Both platforms detect the pipe-table syntax automatically.
