?Frequently Asked Questions

What JSON format is supported?

Arrays of objects are supported. Each object becomes a row, and its keys become column headers.

Can I convert nested JSON?

Nested objects are flattened. Deep nesting may result in complex column names.

Is there a size limit?

Very large files may be slow since all processing happens in your browser.
