Frequently Asked Questions

How are nested objects handled?

Nested objects are flattened using dot notation. For example, {address: {city: 'NYC'}} becomes a column named 'address.city'.

What JSON structure is expected?

An array of objects, like [{name: 'Alice'}, {name: 'Bob'}]. Each object becomes a row, each key becomes a column.

Can I change the delimiter?

Yes. Choose comma (CSV), tab (TSV), or semicolon (common in European locales).
