Frequently Asked Questions
How do I convert CSV to JSON?
Paste your CSV data and the tool uses the first row as field names, turning each remaining row into a JSON object. You get a clean JSON array you can copy or download instantly.
Can I convert JSON back to CSV?
Yes. Paste a JSON array of objects and the tool flattens it into CSV with a header row, which is handy for importing data into spreadsheets like Excel or Google Sheets.
Does it handle commas and quotes inside values?
Yes. The converter follows standard CSV rules, correctly handling quoted fields that contain commas, quotes or line breaks, so your data stays intact in both directions.
Is my data uploaded when converting?
No. The conversion runs entirely in your browser, so spreadsheets, exports and other data never leave your device.
