JSON to CSV Converter – Instant Data Conversion

Convert JSON arrays to CSV files instantly. Perfect for data analysis, Excel imports, and reporting. 100% private – data stays in your browser.

How It Works

Paste a valid JSON array of objects. The tool extracts all keys from the first object to create column headers, then flattens each object into a CSV row. Nested objects/arrays are stringified. The result can be copied or downloaded as a `.csv` file.
