How to Convert a Markdown Table to an XLSX File

Download a Markdown table as a real .xlsx workbook with a bold header row, frozen top row, and numbers stored as numbers.

Direct answer

Paste the Markdown table into the converter and press Download .xlsx. You get a genuine Excel workbook — not a renamed CSV — with the header row bold and frozen, columns auto-sized, and numeric values written as numbers so SUM and AVERAGE work immediately.

When to use this

  • Someone asked for a spreadsheet file rather than a pasted table.
  • The data needs to be attached to an email or uploaded somewhere that expects .xlsx.
  • You want the header row frozen without setting it up by hand.

Steps

  1. Paste the Markdown table into the converter.
  2. Optionally set the sheet name.
  3. Press Download .xlsx.
  4. Open the file in Excel, Numbers, LibreOffice, or Google Sheets.
  5. Check that numeric columns are right-aligned and can be summed.

Example conversion

Markdown input
| Line item | Q1 | Q2 | Q3 |
| --- | ---: | ---: | ---: |
| Licences | 42,000 | 44,500 | 47,000 |
| Support | 12,300 | 12,300 | 13,100 |
| Training | 5,600 | 7,200 | 6,900 |
Tab-separated output Excel splits into cells
Line item	Q1	Q2	Q3
Licences	42,000	44,500	47,000
Support	12,300	12,300	13,100
Training	5,600	7,200	6,900

Common mistakes

  • Do not rename a .csv to .xlsx — Excel will warn that the format does not match and some tools will refuse it outright. A real workbook is a different file format.
  • Do not expect formulas to be recalculated; a cell beginning with = is written as a formula, but the converter does not evaluate it.
  • Do not use a sheet name containing / \ ? * [ or ] — Excel rejects them, so they are stripped automatically.

FAQ

Is the file a real Excel workbook?
Yes. It is a standard OOXML .xlsx package with the workbook, worksheet, and style parts, so Excel, Google Sheets, Numbers, and LibreOffice all open it directly.
Are numbers stored as numbers?
Yes. Values like 1,240 and $980.50 are written as numeric cells, and percentages are stored as their decimal ratio. That is what makes SUM and charting work without a cleanup pass.
Does the file leave my browser?
No. The workbook is assembled in the browser and saved straight to your downloads folder. Nothing is uploaded.
Can I get more than one sheet?
Not from a single conversion — the output is one sheet per table. Convert each table separately and combine them in Excel if you need a multi-sheet workbook.
