JSON to CSV Converter
Convert a JSON array to CSV format for spreadsheets.
About JSON to CSV Converter
Paste a JSON array of objects and convert it to CSV format with auto-detected column headers. Download the result as a .csv file or copy to clipboard. Handles missing keys in rows (fills with empty string).
Use Cases
Exporting API response data to Excel, converting database JSON dumps to spreadsheets, preparing data for analysis tools, sharing data with non-technical users.
How It Works
Extracts all unique keys across all objects as CSV headers. For each object, outputs values in header order, quoting fields that contain commas or newlines.
Frequently Asked Questions
What if some objects are missing keys?
Missing keys are filled with empty strings in the CSV output.
Can I convert deeply nested JSON?
The tool flattens one level deep. Nested objects are stringified. For complex nesting, pre-flatten your JSON.
