JSON to CSV Converter
Options
About this Tool
Easily transform your JSON data into a CSV file. Our JSON to CSV converter takes a JSON array and instantly turns it into a clean, well-formatted CSV, ready for Excel, Google Sheets, or any data analysis tool. It's the perfect way to export API data or JavaScript objects for reporting and analysis.
The tool automatically detects the keys from the first object in your JSON array to create the CSV headers. It then flattens each object into a row, correctly quoting fields to handle commas and newlines.
- Paste your JSON array into the input box.
- The CSV will be generated instantly in the output area.
- Copy the CSV or download it as a file.
- Exporting the results of an API call to a CSV for a report.
- Converting a JavaScript array of objects into a spreadsheet.
- Migrating data from a JSON-based system to a CSV-based one.
- Automatic Header Detection: Creates CSV headers from the JSON keys.
- Smart Formatting: Correctly handles commas and newlines within your data.
- Instant Download: Download your CSV file with a single click.
- Client-Side & Secure: Your data is never sent to a server.
This tool performs the reverse of a CSV-to-JSON conversion. It takes a hierarchical data format (JSON) and flattens it into a tabular one (CSV), making it compatible with traditional spreadsheet applications.
What if the objects in my JSON array have different keys?
The tool will create a column for every unique key found in the array. If an object doesn't have a particular key, that field will be left empty in the CSV.
Does it support nested JSON objects?
This tool works best with flat JSON arrays. Nested objects will be represented as `[object Object]`. For complex nested data, you may need to flatten your JSON first.
What format is the downloaded file?
A standard, UTF-8 encoded `.csv` file.
All calculations and data processing for this tool are performed locally in your browser. We do not send any of your data to our servers, ensuring your information remains private and secure.
