How are nested objects handled?

Nested objects are flattened using dot notation. For example, {user: {name: 'John'}} becomes a column 'user.name' with value 'John'.

Does it handle arrays of different shapes?

Yes! The converter detects all unique keys across all objects in the array and creates columns for each, leaving cells empty where a key doesn't exist in a particular object.

Can I convert CSV back to JSON?

Yes! Use our CSV to JSON converter tool for the reverse operation.

What about special characters in CSV?

Values containing commas, quotes, or newlines are properly escaped according to RFC 4180 CSV standards.
