JSON to CSV Converter
How it works
This converter turns a JSON array of objects into a CSV file for spreadsheets and data imports. It automatically collects keys across objects and outputs a consistent column set.
- For best results, provide a JSON array:
[{"a":1},{"a":2}]. - Choose semicolon delimiter if your system expects European CSV formatting.
- Conversion happens locally in your browser.
