How spreadsheets become Markdown tables
Each worksheet in your workbook is converted to a Markdown pipe table, with the sheet's name as a heading above it. The first row becomes the table header, and every data row follows with columns aligned by pipes. Formulas are exported as their last-calculated values — you get the numbers, not =SUM() expressions — which is exactly what you want when the destination is documentation or an AI prompt.
Multi-sheet workbooks convert in one pass: a workbook with 'Revenue', 'Costs', and 'Summary' sheets becomes one Markdown document with three headed tables, in sheet order.
Spreadsheet features that don't map to Markdown
Markdown tables are plain grids, so Excel's richer features flatten: merged cells lose their span, cell colors and conditional formatting disappear, and charts and pivot-table layouts aren't extracted (though a pivot's output values in cells convert fine). Very wide sheets convert correctly but read poorly — Markdown tables past ten or so columns are hard to scan, so consider trimming columns first. Check date columns after converting; how a date appears can depend on the cell's formatting.
Files are converted and immediately discarded. Free: 3/day up to 25MB. Pro: unlimited, 100MB — enough for genuinely large exports.
Spreadsheet data in LLM workflows
Markdown tables are one of the most reliable ways to hand tabular data to an LLM: the header row stays attached to the values, so models can answer questions about columns without guessing. Analysts use this to drop exports into Claude for analysis, embed readable tables in GitHub READMEs, and keep small datasets version-controlled next to code.
Example: what the Markdown output looks like
A revenue sheet with three columns converts to:
## Revenue
| Month | MRR | New Customers |
| --- | --- | --- |
| April | $498 | 8 |
| May | $612 | 5 |
| June | $684 | 6 |Frequently asked questions
