Data Export tips

📤

Paste a JSON array from any API response and convert to CSV in one click. Download the CSV and open directly in Excel or Google Sheets.

💡

The converter automatically uses all keys from the first object as column headers. Objects with missing keys will have empty cells in those columns.

📊

Nested objects or arrays inside JSON values are serialised as JSON strings in the CSV cell. Flatten your data first if you need nested values as columns.

🔄

Use "← Use as input" after converting to round-trip back to JSON — useful for verifying no data was lost during the conversion.
