Frequently asked questions

What JSON shape do I need?

A top-level JSON array. Each item can be an object (keys become column headers) or an array (positional values). Mixed objects/arrays in one input aren't supported.

What if my objects have different keys?

We take the union of all keys across the array, so a column that only appears in later objects still becomes a CSV column. Empty cells are written for rows that don't have that key.

Are special characters quoted correctly?

Yes. Values containing the delimiter, quotes, or line breaks are wrapped in quotes and internal quotes are doubled (the standard RFC 4180 behaviour).

Is there a size limit?

Up to 2 MB of JSON per conversion, plenty for most real-world exports.
