FAQ

What JSON structure does this expect?

For JSON→CSV, paste a JSON array of objects (e.g. [{"name":"Alice","age":30}]). All objects should share the same keys which become CSV column headers.

What delimiters are supported?

Comma (,), semicolon (;), and tab. Use semicolons for European locales where commas are used as decimal separators.

Can I convert CSV back to JSON?

Yes. Switch to the CSV→JSON tab. The first row is treated as headers and each subsequent row becomes a JSON object.
