JSON to CSV Converter
Convert JSON data to CSV.
How JSON to CSV conversion works
Step 1
Paste a JSON array
Add a JSON array of objects into the input box, for example a list of records exported from an API.
Step 2
Convert to CSV
The tool collects every key found across all objects to build the header row, then writes one CSV row per object.
Step 3
Copy or download
Copy the CSV output for use in a spreadsheet or import into another tool.
Frequently asked questions
What input does this expect?
A JSON array of objects, such as [{"name":"A"},{"name":"B"}]. A single object or non-array JSON will show a validation message.
What happens if objects have different fields?
The header row includes every field found across all objects; any object missing a given field simply gets an empty value in that column.
Is my JSON uploaded anywhere?
No. Conversion happens locally in your browser.
