Question 1

What JSON structure does this support?

Accepted Answer

The input must be a JSON array of objects, for example [{"name":"Alice","age":30}]. Each object becomes a row; the keys become column headers.

Question 2

What if objects have different keys?

Accepted Answer

All unique keys across all objects are used as column headers. Objects missing a key will produce an empty cell for that column.

Question 3

Is my data uploaded anywhere?

Accepted Answer

No. Conversion runs entirely in your browser. Your data never leaves your device.

Question 4

Can I convert CSV back to JSON?

Accepted Answer

Not currently, but a CSV to JSON converter is on the roadmap.
