CSV to JSON
Convert CSV with a header row into a JSON array of objects, or a JSON array back into CSV.
Frequently asked questions
Which CSV format is supported?
RFC 4180: fields separated by a comma (or the delimiter you pick), optionally in double quotes; quotes inside a field are doubled (""); quoted fields may contain commas and line breaks.
Are numbers and true/false converted?
Only if you tick “detect numbers and booleans”. Otherwise every value stays a string, which is safer for things like zip codes and phone numbers that start with 0.
Is my data uploaded?
No. The conversion runs in your browser and the data is not put into the page link.
