What Is a JSON to CSV Converter?

A JSON to CSV Converter transforms data stored in JavaScript Object Notation into comma-separated values. JSON is commonly used by APIs, websites, applications, and databases, while CSV is easier to open and analyze in spreadsheet software.

This converter reads JSON objects, identifies available keys, creates matching CSV columns, and places each record into a structured row. It can also flatten nested objects so complex data becomes easier to review.

Why Convert JSON Data to CSV?

CSV files are useful when data needs to be filtered, sorted, shared, imported, or analyzed in tools that work better with rows and columns. Converting JSON to CSV can save time when working with API exports, business records, product data, analytics, customer lists, and development projects.

Handling Nested JSON

Nested JSON can contain objects inside other objects. When the flattening option is enabled, this tool creates readable column names such as address.city and address.country. When flattening is disabled, nested values remain stored as JSON text inside a CSV cell.

Common Questions

JSON to CSV Converter FAQs

Helpful answers about converting JSON files and data into CSV format.

How do I convert JSON to CSV?

Paste your JSON into the editor or upload a .json file, select your preferred options, and click Convert JSON to CSV. You can then preview, copy, or download the result.

Can this tool convert nested JSON?

Yes. Keep the Flatten nested JSON option enabled to convert nested object properties into separate columns using readable dot notation.

Can I open the CSV file in Excel or Google Sheets?

Yes. The downloaded CSV file can be opened or imported into Microsoft Excel, Google Sheets, LibreOffice Calc, and many other data tools.

What JSON format works best?

An array of objects works best. Each object becomes a CSV row, while the keys in those objects become column headings.
