Advanced JSON to CSV Converter (Online & Free)
Effortlessly convert your complex JSON data into a clean, structured CSV file with our powerful online tool. Unlike basic converters, our tool intelligently handles **nested objects and expands arrays into multiple rows**, giving you a clean, usable dataset. It's perfect for developers working with API responses, data scientists handling complex data structures, and anyone needing to convert JSON to a spreadsheet-friendly format like Excel or Google Sheets.

How to Use the JSON to CSV Converter
- Provide Your JSON Data: You have two easy options. You can either paste your raw JSON code directly into the editor on the left, or you can click the "Upload File" button to select a `.json` file from your computer. You can also drag and drop a file directly onto the editor.
- See the Instant Preview: As soon as you provide the data, our tool automatically processes it and generates a live preview of the resulting CSV in the table on the right. This allows you to verify the conversion in real-time.
- Customize and Download: Choose your preferred CSV separator (comma, semicolon, or tab) from the dropdown menu. Once you are satisfied, click the "Download CSV" button to save the file to your device.
Why Our Converter Stands Out
While many converters exist, our tool is built to handle the real-world complexities of JSON data. Here's what makes it superior:
- Advanced Array Handling: This is our key feature. If a JSON object contains an array of items (like multiple phone numbers for one contact), our tool smartly creates a separate row for each item in the array, duplicating the other data. This is crucial for creating a clean, flat CSV file ready for analysis.
- Deeply Nested Object Support: Our converter automatically "flattens" nested objects, using dot notation (e.g., `user.address.city`) as headers to preserve the data's structure and context.
- Complete Privacy & Security: Your data's security is guaranteed. The entire conversion process happens locally in your web browser. Your sensitive information is never sent to or stored on our servers.
Frequently Asked Questions (FAQ)
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. It's the most common format for data sent from a server to a web page (API responses).
Why do people convert JSON to CSV?
CSV (Comma-Separated Values) is the most compatible format for spreadsheets and data analysis software. People convert JSON to CSV to easily open, analyze, and visualize the data in programs like Microsoft Excel, Google Sheets, or to import it into a database.
