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.
