About the CSV to JSON tool
Paste CSV to get a JSON array of objects, using the first row as keys. Delimiters are auto-detected, and quoted fields, doubled quotes and newlines inside quotes are handled correctly.
Numbers stay numbers where they look numeric, so results can be piped straight into code without string cleanup.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
