JSON to CSV
Convert JSON arrays to CSV format.
About JSON to CSV
JSON to CSV converts a JSON array of objects into a comma-separated values file, with each object becoming a row and each unique key becoming a column header. This makes it easy to import JSON data from an API into Excel, Google Sheets, or any database that accepts CSV imports. Nested objects are flattened and arrays within rows are serialized to string.

Frequently Asked Questions
Is JSON to CSV free?
Yes, completely free. No signup, no account, no usage limits. Use it as much as you need.
Is my data secure?
All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.
What happens to nested JSON objects during conversion?
Nested objects are flattened using dot notation by default (e.g., address.city becomes its own column). Nested arrays are serialized as a JSON string within the cell.
Does the input need to be an array of objects?
Yes. The converter expects a JSON array where each element is an object with consistent keys. A single object or a plain array of values will not produce a meaningful CSV.
