Frequently Asked Questions
How does the JSON to CSV conversion handle nested objects?
Our converter is designed for flat data extraction. If your JSON contains nested objects, they are currently stringified into the cell. For the best CSV results, we recommend passing a flat array of objects where each key represents a column header.
Can I download the converted CSV file?
Yes. Once your JSON is converted, you can use the professional Download button in the result editor to save the data as a .csv file, which is fully compatible with Microsoft Excel, Google Sheets, and other spreadsheet software.
What happens if objects in my array have different keys?
The converter intelligently scans all objects in your JSON array to build a comprehensive list of unique keys. These keys become the CSV headers, ensuring that no data points are missed, even if some objects are missing certain fields.
