Frequently Asked Questions

FAQs about JSON to CSV

What JSON structure does this expect?

The tool works best with a JSON array of objects (e.g., [{...}, {...}]). If you pass a single object, it will be treated as a one-row table.

How are nested objects handled?

Nested objects and arrays are converted to their string representation in the CSV cell. For deeply nested data, consider flattening first.

Does it handle special characters?

Yes. Values containing commas, double quotes, or newlines are automatically wrapped in double quotes and escaped per the CSV standard.

Can I open the output in Excel?

Yes. Copy the output and paste it into a text file with a .csv extension, then open it with Excel or Google Sheets.

Is my data safe?

Yes. All conversion happens in your browser. No data is sent to any server.
