Frequently asked questions

What JSON shape does this expect?

An array of flat objects, like [{"name":"Alice","age":30}, ...]. Column headers are taken from the union of all keys across every object, in the order they first appear.

What happens to nested objects or arrays?

Nested values are converted to their JSON string representation and placed in a single cell, since a spreadsheet cell has no native way to represent nested structure.

What if some objects are missing a field?

Missing fields are left as an empty cell in that row - every row uses the same full set of columns.

Is my data uploaded anywhere?

No. Conversion happens locally in your browser using JavaScript - nothing you paste is sent to a server.
