Frequently asked questions
What JSON shape does it expect?+
An array of objects works best, for example [{ "name": "Kim" }]. A single object is treated as one row.
How are nested objects handled?+
Nested keys are flattened with dot notation, so { user: { name: "Kim" } } becomes a column named user.name.
Is my data uploaded?+
No. The conversion runs in your browser and your data is never sent to a server.
