Free JSON to CSV Converter — Frequently Asked Questions
?Frequently Asked Questions
What JSON structures can be converted?
The tool handles arrays of objects (most common), nested objects, mixed types, and arrays within objects. It flattens complex structures into a flat tabular format.
Can I open the CSV in Excel?
Yes. The output CSV file is fully compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications.
How are nested objects handled?
Nested objects are flattened using dot notation for column headers (e.g., "address.city"). Arrays are joined or expanded based on the structure.
Is there a size limit?
The tool processes data in your browser, so it depends on available memory. JSON files up to several MB are handled without issues.
