How it works

Paste your markdown

Paste markdown text with one or more tables using standard | column | syntax. Works with ChatGPT, Claude, and any AI output.

Edit cells inline

Click any cell to edit it directly. The markdown above updates in real time so you can copy it back whenever you want.

Copy or export

Hit Compact to strip padding, Copy markdown to grab the source, or Download .xlsx to get a spreadsheet with each table on its own sheet.

Frequently asked questions

Yes. ChatGPT, Claude, Gemini, and most AI tools output tables in standard markdown format with pipe characters. Paste the output directly and start editing immediately.

Each table gets its own sheet in the Excel file. Sheet names are Table 1, Table 2, and so on.

It strips all column padding from the markdown, turning wide padded tables into minimal pipe-separated syntax. Useful before pasting back into code or documentation.

No. Standard markdown tables require a header row followed by a separator row (|---|---|). Tables without that format will not be detected.

No. Everything happens entirely in your browser using JavaScript. Your data never touches a server.
