Excel (XLSX) to Markdown Converter

Turn an Excel workbook into Markdown pipe tables — one table per sheet, headers detected automatically. This is the fastest way to drop a data table into a GitHub README, a Notion doc, a technical spec, or any Markdown-based publication. Multi-sheet workbooks emit one Markdown section per sheet with the sheet name as an H2 heading, so you can paste the entire output into one document without post-processing.

What this converter preserves

Each worksheet becomes its own H2 section followed by a pipe table — trivial to copy into a README
First row is treated as the header row (matches Excel's "My table has headers" default)
Numeric formatting is preserved: currency, percentages, and dates render as they display in Excel, not as raw floats
Blank rows and columns at the edges are trimmed so the Markdown table has no phantom empty cells

When you'd use this

Turning a data-analysis spreadsheet into a GitHub README table for an open-source project
Publishing a pricing sheet or feature-comparison matrix on a company blog without exporting as CSV first
Converting Excel-based tracker sheets into Notion or Confluence tables while preserving structure
Feeding tabular financial or operational data into LLM prompts without the token cost of CSV headers on every row

How it works

1

Upload the .xlsx file

Drop your Excel workbook onto the upload area. .xls (old format) is not supported — save as .xlsx first.
2

Convert

Click Convert. Each worksheet is processed in turn and combined into one Markdown output.
3

Copy the tables

Preview the Markdown, copy it, or download as .md. Each sheet is clearly separated by its own heading.

Frequently asked questions

What if my workbook has multiple sheets?

Each sheet becomes its own H2 heading in the output, followed by the sheet's data as a pipe table. Sheets are emitted in the order Excel stores them.

Are formulas evaluated?

The last-calculated cached value is used — the same value Excel displays. Formulas themselves are not shown in the Markdown output. Recalculate in Excel and save before uploading if a formula's cached value is stale.

Does it handle merged cells?

Merged cells are unmerged in the Markdown output — the value goes into the top-left cell, other cells in the merge become empty. Markdown tables don't support cell merging.

What about charts and pivot tables?

Charts and pivot-table visualizations are not converted (Markdown has no chart syntax). Only the underlying data table is included. If you need the chart, export it separately as an image from Excel.

Can it handle very wide sheets?

Yes, but Markdown pipe tables render poorly beyond ~10 columns. Consider splitting a wide sheet into narrower logical groups before conversion, or use HTML tables instead of Markdown for that particular table.
