Frequently asked questions
What JSON format is supported?
This tool supports JSON arrays of objects. Each object becomes a row and each key becomes a column. Example: [{"name":"James","age":30},{"name":"Anna","age":25}]
Can I open the CSV in Excel?
Yes! Download the CSV file and open it directly in Excel, Google Sheets or any spreadsheet application.
What if my JSON has nested objects?
Nested objects are converted to JSON strings in the CSV cell. For deeply nested data you may need to flatten it first.
Is my data safe?
Yes. All conversion happens entirely in your browser — your data never leaves your device.
