Frequently asked questions

What JSON structure does this expect?

A JSON array of flat objects, e.g. [{"name":"Alice","age":30}]. Nested objects or arrays are converted to their JSON string form inside the CSV cell, since CSV has no concept of nesting.

Does this handle commas and quotes inside values?

Yes. Any field containing a comma, quote or newline is automatically wrapped in quotes, with internal quotes escaped, following standard CSV rules.
