Excel to Markdown table converter (XLSX) - free online tool

An Excel to Markdown table converter turns a spreadsheet workbook into Markdown tables you can paste into docs. Textavia exports one Markdown table per sheet, so you can document data in a README, wiki, or issue without screenshots or attachments.

Conversion runs locally in your browser. The workbook you upload stays on your device.

1. Upload an Excel file: Upload a workbook like report.xlsx.
2. Choose header and limits: Decide whether the first row is a header, and set a max row limit per sheet.
3. Copy the Markdown: Copy the output tables and paste them into your docs.

• Docs that diff well: Markdown tables are easier to review in pull requests than binary files.
• No screenshots: Readers can copy cell text and search it.
• One output for many sheets: Multi-sheet workbooks become multiple tables with clear headings.

The converter exports cell values as text in a simple grid. It does not export charts, images, pivot tables, or formatting like colors and fonts.

If your sheet uses formulas, the output uses the displayed cell value in most cases. For clean Markdown tables, try to keep the exported range as a plain grid with one header row and consistent columns.

Use case 1: Publish a spreadsheet snapshot in a repo

If an internal spreadsheet drives a process, export a small slice to Markdown so the repo docs show the current view.

Use case 2: Add a data appendix to documentation

Docs sometimes need reference tables, feature matrices, or environment lists that start life in Excel. Converting to Markdown keeps the docs readable.

Use case 3: Turn Excel into JSON workflows

Convert Excel to Markdown tables, then export the table as JSON with Markdown table to JSON when you need a dataset for scripts.

Basic example (one sheet)

Imagine a sheet named Owners with three columns. The output will look like this:

## Owners

| service | owner | tier |
| :--- | :--- | :--- |
| auth | dina | 1 |
| billing | evan | 2 |

Advanced example (multiple sheets)

If your workbook has multiple sheets, the tool can add a heading for each and export one table per sheet:

## Services

| name | status |
| :--- | :--- |
| auth | active |
| payments | blocked |

## Contacts

| team | slack |
| :--- | :--- |
| platform | #platform |
| support | #support |

The file is not supported

XLSX is the most reliable format. Some .xls files may work, but if conversion fails, save the workbook as .xlsx and try again.

Merged cells produce odd output

Markdown tables are rectangular. Merged cells in Excel do not map cleanly to Markdown columns. Fix: unmerge cells in the range you care about, or move the data into a simple grid before converting.

The output is huge

Large sheets create huge Markdown tables. Fix: lower the max rows per sheet so the output stays readable in docs, then link to the full workbook elsewhere.

• Use clear headers: If your first row is column names, keep First row is header on. If not, turn it off so the tool generates Column 1, Column 2, and so on.
• Limit data rows for docs: Docs tables are reference material, not raw exports. Use a row limit and include only the slice your reader needs.
• Edit after export: For quick edits, use the Markdown table creator to adjust alignment and wording. If you need a single table, copy only the rows you want into a new sheet before converting.

• Convert copied sheet cells with Google Sheets to Markdown table.
• Convert CSV exports with CSV to Markdown table.
• Export a Markdown table into data using Markdown table to JSON or Markdown table to CSV.

Excel parsing and Markdown generation run locally in your browser. Textavia does not upload or store your spreadsheet file.
