Frequently Asked Questions

How do I convert JSON to CSV?

Simply paste your JSON code or upload a .json file into the input box. The tool will automatically parse the data and generate a CSV preview. Click “Download CSV” to save the file to your computer.

Can I open the result in Excel?

Yes! The downloaded CSV file is fully compatible with Microsoft Excel, Google Sheets, and other spreadsheet software. Just open the file, and your data will be organized into columns.

Does it handle nested JSON objects?

Yes. Our converter uses “flattening” logic to turn nested arrays and objects into a flat table structure, ensuring no data is lost during the conversion.

Is my data safe?

Absolutely. We use Client-Side Processing. Your JSON data never leaves your browser, making it safe for confidential API data or customer lists.

Is there a file size limit?

Since the processing is local, there are no hard limits enforced by our server. However, very large files (e.g., 50MB+) may depend on your browser’s performance capabilities.
