About the CSV to JSON
Paste CSV data and convert it into clean, well-formed JSON. Use the header-row option to turn the first row into object keys, or keep rows as arrays. Quoted fields and escaped quotes are handled correctly.
Conversion runs entirely in your browser, so spreadsheets and exports never leave your device — ideal for sensitive data.
