FAQ
Common questions about the CSV to JSON converter.
How do I convert CSV to JSON?
Paste your CSV data (first row = headers) into the editor and press Convert. Each row becomes a JSON object with those headers as keys.
Does it handle quoted fields?
Yes. The parser correctly handles quoted fields that contain commas, newlines, and escaped (doubled) quote characters.
Can I change the delimiter or quote character?
Yes. Use the Delimiter and Quote character settings before converting to support tab, semicolon, pipe or other separators.
Are numbers and booleans typed correctly?
Yes. Integer-looking values become numbers, and "true"/"false"/"null" strings are converted to real JSON booleans and null.
Is my data uploaded to a server?
No. Everything is processed entirely in your browser. Your data never leaves your device.
Can I download the JSON as a file?
Yes. Use the Download button after converting to save the output as a data.json file.
