JSON to CSV Converter

Convert JSON array to CSV format instantly in your browser

What is JSON to CSV Converter?

The JSON to CSV Converter is a free online tool that transforms JSON arrays into comma-separated values (CSV) format instantly in your browser, making it easy to export data to spreadsheets, databases, and data analysis tools. JSON is the standard format for APIs and web applications, but business users, data analysts, and reporting tools typically work with CSV files that open directly in Excel, Google Sheets, and similar applications. This tool automatically extracts column headers from the JSON keys, maps each object to a row, and handles nested values gracefully. Whether you are exporting API data for a report, preparing data for import into a database, or sharing structured data with non-technical team members, this converter handles it in one click.

Frequently Asked Questions

Here are answers to the most common questions about the JSON to CSV Converter:

What JSON structure works best for CSV conversion?

The tool works best with a flat JSON array of objects where each object has the same keys. For example: [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Each object becomes a row and each key becomes a column header.

What happens with nested JSON objects?

Nested objects are converted to string representations in the CSV cell. For deeply nested data, consider flattening your JSON structure first or using a dedicated data transformation tool for complex nested-to-flat conversions.

How are special characters handled in CSV output?

Values containing commas, quotes, or newlines are automatically wrapped in double quotes and internal quotes are escaped according to RFC 4180 CSV standard, ensuring the output opens correctly in Excel and Google Sheets.

Can I convert a single JSON object (not an array)?

The tool is optimized for JSON arrays. For a single object, wrap it in an array first: [{"key":"value"}]. This will produce a CSV with one data row plus the header row.

What if my JSON objects have different keys?

The converter uses all unique keys found across all objects as column headers. Objects missing a particular key will have an empty cell for that column in the CSV output.
