Simply paste your JSON data into our converter, choose your formatting options, and click "Convert to CSV". Our tool handles the conversion instantly in your browser - no registration or payment required. You can then download the CSV file or copy the output directly.

Yes! Our converter automatically flattens nested JSON objects using dot notation. For example, {"user": {"name": "John", "age": 30}} becomes columns "user.name" and "user.age". You can enable or disable this feature in the conversion options.

Our browser-based converter can handle files up to 100MB, depending on your device's memory. For larger files, we recommend breaking them into smaller chunks. The conversion happens locally in your browser, so your data remains private and secure.

JSON arrays are converted intelligently - if the array contains objects, each object becomes a row. If an array contains primitive values, they're joined with commas in a single cell. For arrays within objects, they can be flattened into separate columns or kept as comma-separated values.

Absolutely! You can choose different delimiters (comma, semicolon, tab, pipe), quote characters, include or exclude headers, and control how nested objects are flattened. These options ensure compatibility with various spreadsheet applications and data systems.

Yes, your data is completely safe. All conversion happens locally in your browser - no data is sent to our servers. Your JSON and CSV data never leaves your device, ensuring maximum privacy and security for sensitive information.

Our converter handles inconsistent JSON structures gracefully. Missing properties are filled with empty values, and additional properties in some objects create new columns. The tool ensures all data is preserved while maintaining a valid CSV structure.

Perfect for API data export! Many APIs return JSON responses that need to be converted to CSV for analysis, reporting, or importing into other systems. Our tool handles complex API response structures including pagination metadata and nested data objects.

Yes! Our converter generates CSV files that are fully compatible with Excel, Google Sheets, and other spreadsheet applications. You can choose the appropriate delimiter (comma for international systems, semicolon for European Excel) to ensure perfect compatibility.

Currently, our tool processes one JSON file at a time to ensure optimal performance and accuracy. For multiple files, you can merge them into a single JSON array or convert them individually. We recommend this approach for better control over the conversion process.

Yes, our JSON to CSV converter is completely free to use with no registration required. You can convert unlimited JSON data, download CSV files, and access all features without any charges. The tool is designed to be accessible to developers and data professionals worldwide.
