Frequently Asked Questions
How do I convert JSON to CSV?▾
Paste a JSON array of objects into the input field and click Convert. The tool uses the keys of the first object as CSV headers and converts each object to a CSV row. You can download the result as a .csv file.
What JSON structure works best for CSV conversion?▾
A flat array of objects works best: [{"name":"Alice","age":28},{"name":"Bob","age":34}]. Nested objects are stringified into the CSV cell. If you have nested data, flatten it first using JSON tools.
Can I open the exported CSV in Excel or Google Sheets?▾
Yes. The exported CSV uses standard comma-delimited format compatible with Microsoft Excel, Google Sheets, Apple Numbers, and any other spreadsheet application.
