Frequently asked questions
What JSON format does it expect?
An array of objects, like [{"name": "Jane"}, {"name": "John"}]. The keys become columns. A single object is treated as one row.
How are nested objects handled?
Nested objects and arrays are serialized back to JSON text inside their cell, so no data is lost even though CSV is a flat format.
Is my data uploaded?
No. The conversion runs entirely in your browser, so your JSON never leaves your device.
