What JSON format is supported?

We support an array of objects. Each object in the array becomes a row, and the keys become the column headers.

Can I convert nested JSON?

Currently, we support flat JSON objects. Nested objects will be stringified within their cells.

Is there a size limit?

You can convert JSON files up to 5MB directly in your browser.
