FAQ
How do I convert CSV to JSON online?
Paste your CSV with a header row, pick CSV→JSON, choose a delimiter, and copy the JSON array of row objects.
How to export a JSON array to CSV?
Select JSON→CSV, paste an array of objects, and copy the result. Keys from the first object become the CSV header line.
What delimiter should I use for CSV to JSON?

Yes—the header row defines property names for each column in every object of the output array.
