ADVERT
JSON to CSV Converter
Convert JSON arrays into CSV format instantly. Paste JSON, tune nesting options, and download spreadsheet-ready output.
How to use this tool
- Paste a JSON array of objects into the input editor.
- Choose nested object handling and header ordering options.
- Copy or download the generated CSV and verify the detected columns.
Conversion behavior
- The converter merges keys across all rows into a single header set.
- Missing keys in individual rows are exported as blank cells.
- Values are escaped for commas, quotes, and line breaks to keep CSV valid.
Data prep tips
- Use Pretty Print before editing large payloads to spot JSON syntax issues faster.
- Keep the root value as an array, even when converting a single object.
- Use flatten mode for analytics pipelines and stringify mode when preserving nested blobs.
FAQ
- What JSON structure is supported?
- The root must be an array of objects. Non-array roots are rejected to prevent ambiguous header mapping.
- How are nested values handled?
- You can flatten nested objects into dot-path keys or keep object values as JSON strings.
- Will column order stay stable?
- Yes. You can keep detected key order or switch to alphabetical ordering for consistency.
