How it works
TableSwap parses whatever you paste as CSV, JSON, or a Markdown table, shows it as a sortable table so you can spot-check the data, and converts it to whichever format you choose — all directly in your browser. Nothing you paste is ever uploaded.
Frequently asked questions
Is this free to use?
Yes. There's no sign-up and no limit on how many conversions you run.
Do you store the data I paste in?
No. The conversion runs entirely client-side in your browser, and nothing you paste is uploaded or stored.
What JSON shape do you expect?
An array of flat objects, one per row, like [{"name":"Ada","age":36}]. A single object is treated as one row.
Does it guess number or boolean types from CSV or Markdown?
No. Values coming from CSV or Markdown are kept as plain text, including in the JSON output, so a value like "007" never silently loses its leading zero.
