What JSON structure is supported?

The input must be a JSON array of objects, where each object represents a row. All objects should share the same keys, which become the CSV column headers. Nested objects are flattened with dot notation (e.g. address.city).

How are array values handled?

Array values in a field are joined with a semicolon by default and placed in a single cell. Nested arrays of objects are flattened to a JSON string representation.

What delimiters are supported?

Comma (,) for standard CSV, semicolon (;) for European locales where commas are used as decimal separators, and Tab for TSV (tab-separated values) that paste directly into spreadsheets.

Can I download the CSV?

Yes — click Download to save the output as a .csv file. The file includes the correct UTF-8 BOM so accented characters display correctly in Excel.
