Need to get your JSON data into a spreadsheet or a CSV-based workflow? This tool converts a JSON array of objects into CSV format. The keys from your objects become the column headers, and each object becomes a row in the output.
Paste your JSON array, and the tool generates CSV output that you can copy to your clipboard or download as a file. Values containing commas or quotes are automatically escaped according to the CSV specification.

$ cat FAQ.md
What JSON format does this tool accept?▶
This tool accepts a JSON array of objects. Each object becomes a row, and the keys become column headers. For example: [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}].
How are nested objects handled?▶
Nested objects and arrays are serialized as JSON strings within the CSV cell. For flat CSV output, flatten your JSON objects before converting.
Is my data sent to a server?▶
No. All conversion happens entirely in your browser. Your JSON data never leaves your device.
Can I download the CSV file?▶
Yes. Click the download button to save the CSV output as a file. You can also copy it to your clipboard using the copy button.
