Pro Tips
- •The first row of the sheet becomes the Markdown table header - make sure it contains your column names
- •Pipe characters (|) inside cell values are automatically escaped so they don't break the table structure
- •Line breaks inside cells are converted to spaces, since Markdown tables can't contain multi-line cells
- •If your workbook has multiple sheets, switch between them with the Sheet selector - each one converts independently
- •The whole file is read and converted locally in your browser - nothing is uploaded anywhere

Frequently Asked Questions
Can I convert a workbook with multiple sheets?
Yes. After uploading, use the Sheet selector to choose which sheet to convert. Each sheet is converted independently into its own table.
What happens to pipe characters in my data?
Any literal | character inside a cell is automatically escaped as \| so it doesn't get mistaken for a column separator.
Can a cell contain multiple lines?
No. Markdown tables don't support multi-line cells, so line breaks within a cell are converted to single spaces.
Is my spreadsheet uploaded to a server?
No. The entire file is read and converted locally in your browser using the SheetJS library. Your data never leaves your device.
Does formatting from Excel carry over?
No. Colors, fonts, and borders are not preserved - only cell values are converted, since Markdown tables have no styling support.
