Got Questions? We have you covered

Yes! The converter automatically flattens nested objects by default, creating column names like 'user.name' or 'address.city'. You can disable this feature in settings if you prefer to keep nested structures as JSON strings.
You can choose how arrays are handled: 'Expand' joins array values with semicolons, 'Stringify' converts arrays to JSON strings, or 'Ignore' skips array fields. This setting is available in the CSV Settings panel.
Yes! You can paste JSON code directly into the text area, and the converter will process it just like an uploaded JSON file. The tool also includes a 'Format JSON' button to beautify your JSON before conversion.
The tool supports three delimiters: Comma (,), Semicolon (;), and Tab. Choose the delimiter that works best for your use case. Comma is standard for most applications, while semicolon is common in European locales, and tab is useful for TSV format.
Yes! After conversion, you can preview the CSV output directly in the tool. You can also open a full-screen preview modal to see the complete CSV content before downloading or copying.
Yes. All conversion happens entirely in your browser. Your JSON files and data are never uploaded to any server—everything is processed locally for maximum security and privacy.
Yes, the tool can handle reasonably large JSON files. Very large files (several megabytes) may take a moment to process, but the tool is optimized for performance. The preview shows the first 5000 characters, but the full CSV is available for download.
Yes! After conversion, click the 'Copy CSV' button to copy the entire CSV content to your clipboard. This is perfect for quickly pasting into Excel, Google Sheets, or other applications.
The converter collects all unique keys from all objects in an array to create comprehensive headers. If some objects have missing fields, those cells will be empty in the CSV, ensuring all data is preserved.
Yes! The JSON to CSV converter works on all devices including smartphones, tablets, and desktops. You can convert JSON files on the go, though larger files are easier to handle on desktop.
