Frequently Asked Questions
How do I convert nested JSON to CSV?
Our converter automatically flattens nested objects using dot notation. For example, {"user": {"name": "John"}} becomes a column named "user.name" with value "John."
Can I open the CSV output in Excel?
Yes. Click "Download CSV" and open the file directly in Microsoft Excel, Google Sheets, or any spreadsheet application. The format is fully compatible.

Yes. The converter expects a JSON array of objects. Each object becomes a CSV row, and object keys become column headers.
