Free JSON to CSV Converter

Why Convert JSON to CSV?

JSON (JavaScript Object Notation) is the standard format for web APIs, but it is not easily readable by non-technical users or compatible with traditional spreadsheet software like Microsoft Excel or Google Sheets. Converting it to CSV solves this problem.

• Data Analysis & Reporting: Business Analysts need data in tabular formats (rows and columns) to create charts, pivot tables, and reports. Converting a JSON API response to CSV allows them to import it instantly into Excel.
• Flattening Nested Data: JSON data can be deeply nested (e.g. an object inside an object). Our advanced converter features a "Flatten Nested Objects" engine. It automatically detects deep arrays and objects and converts them into flat, dot-notated columns like contact.email.
• Robust PapaParse Engine: Utilizing the industry-standard PapaParse library, our tool flawlessly handles string escaping, custom delimiters, and quotes, ensuring that text containing commas doesn't break your spreadsheet columns.
• 100% Client-Side Privacy: When working with database dumps or sensitive user data, privacy is critical. Our converter processes all JSON data entirely inside your browser. No files are ever sent to remote servers.
