About this tool
What is a JSON to CSV converter?
A JSON to CSV converter turns a JSON array into CSV format so the data can be opened in spreadsheet tools like Excel or Google Sheets. It is useful when you want rows and columns from structured JSON data.
How to convert JSON to CSV
Paste a valid JSON array into the input box, click Convert, and then copy or download the CSV output. The conversion happens instantly in your browser.
What happens to nested objects or arrays?
Nested values are converted to JSON strings in the CSV cells to keep the output consistent and preserve the original structure.
Does RazTools upload my data?
No. This tool runs in your browser. Your JSON stays on your device.
Why is there a 1MB free limit?
Large conversions can be heavier in the browser. We plan to support larger files in a future Pro option.
