JSON to CSV
Convert a JSON array to CSV format for spreadsheets.
Frequently Asked Questions
What JSON structure does this tool support?
The tool works best with a JSON array of objects where each object has the same keys. Each object becomes a row, and the keys become column headers.
What if my objects have different keys?
The tool collects all unique keys across every object and uses them as headers. Missing values are left blank in the CSV.
Are special characters handled?
Yes — values containing commas, quotes, or newlines are automatically wrapped in double quotes and escaped per the RFC 4180 CSV standard.
Can I import the CSV into Excel or Google Sheets?
Yes — the output CSV is compatible with both Excel and Google Sheets. Use the Download button to save the file, then open it directly.
