How to convert Excel to a Markdown table

  1. Drop the spreadsheet into the box above — .xlsx, legacy .xls, .csv, .tsv or OpenDocument .ods. Parsing runs on your own device; nothing uploads.
  2. Every sheet becomes its own section, headed with the sheet's name, holding one Markdown table.
  3. Download the .md or copy the tables straight into an AI chat, a README or documentation — anywhere Markdown lives.

What the converter does with your workbook

Spreadsheets are the easiest format on this site to convert honestly, because a sheet already is a table — no reconstruction, no guessing. What matters is what happens to the parts of a workbook that aren't just a grid:

  • One table per sheet, in workbook order — each headed ## Sheet: Name, so a multi-tab workbook keeps its shape and an AI can be asked about a tab by name.
  • Formulas arrive as their computed values. A cell holding =SUM(B2:B4) comes out as the number it evaluates to — which is what you want in AI context, where the model needs the answer, not the recipe.
  • The first row becomes the table header — the near-universal spreadsheet convention, applied as-is.
  • Empty rows are dropped, ragged rows padded so every table is a valid, renderable Markdown grid.

A real example

This is actual output from this converter. The input was a two-sheet workbook — monthly metrics with a =SUM() total row, and a small pricing tab:

## Sheet: Growth

| Month | Signups | Churn |
| --- | --- | --- |
| June | 240 | 12 |
| July | 310 | 9 |
| August | 405 | 14 |
| Total | 955 | |

## Sheet: Pricing

| Plan | Price |
| --- | --- |
| Free | 0 |
| Pro | 12 |

Both tabs survived as named sections, and the Total row shows 955 — the formula's computed value, not "=SUM(B2:B4)". The AI reads results, the way a person reading the spreadsheet would.

The fine print

Charts don't convert — their source data does. A chart in Excel is a picture drawn from cells; Markdown has no charts. The cells the chart was built from come through as a table, which for AI purposes is usually better than the picture would have been.

Formatting is not data. Cell colours, conditional formatting, merged-cell cosmetics and column widths don't survive — the values do. If a colour encodes meaning ("red = overdue"), add that as a column before converting.

Very wide sheets make very wide tables. A 40-column sheet converts correctly but reads badly anywhere. For AI context, consider deleting the columns that don't matter first — fewer tokens, better answers.

Password-protected workbooks can't be opened in the browser. Remove the protection, then convert.

Excel conversion questions

Is this Excel to Markdown converter free?

▼

Yes — free, unlimited, no account. Conversion runs in your browser, so there's nothing to meter.

Is my spreadsheet uploaded anywhere?

▼

No. The workbook is parsed on your own device — which matters, because spreadsheets are so often the most sensitive files people have: budgets, salaries, customer lists.

Do formulas convert?

▼

Their results do. Each formula cell arrives as its computed value, the same number you see in Excel. The formula text itself isn't included — AI context almost always wants the answer, not the recipe.

What happens with multiple sheets?

▼

Every sheet becomes its own '## Sheet: Name' section with its own table, in workbook order. Ask the AI about the 'Pricing' tab and it knows exactly which table you mean.

Can I convert CSV and TSV files too?

▼

Yes — both become Markdown tables directly, with quoted fields handled properly. Legacy .xls and OpenDocument .ods work as well.

How do I convert a Google Sheet?

▼

Download it first: in Google Sheets, File → Download → Microsoft Excel (.xlsx), then drop that file here. There's a full guide on our Google Sheets page.
