Frequently asked questions
How are columns turned into keys?＋
The first row is treated as headers, and each following row becomes an object keyed by those headers.
Does it detect numbers and booleans?＋
Yes — values that look like numbers or booleans are converted, so your JSON isn't entirely strings.
What about commas inside a field?＋
Quoted fields that contain commas are parsed correctly, following standard CSV rules.
