Is my JSON or CSV uploaded to Convertr?

No. Conversion runs entirely in your browser. Pasted data, headers, field names and values are not uploaded to Convertr servers.

How are nested JSON objects converted to CSV?

Nested object keys are flattened with dot notation. Arrays inside objects are encoded as JSON strings so each CSV cell keeps the original value.

Which CSV delimiters are supported?

The converter supports commas, semicolons, tabs and pipes. Auto-detect chooses the delimiter that creates the most consistent rows.

Can I convert CSV with quoted fields and line breaks?

Yes. The CSV parser supports quoted fields, escaped quotes, commas inside quotes and multiline values.
