Is JSON 与 CSV 互转 free? Do I need to register?

Yes, it's completely free. No registration required for most tools. Tools that store personal data (e.g., favorites, conversion history) optionally support login for cross-device sync.

Do I need to install anything to use JSON 与 CSV 互转?

No installation needed. Open the web page and use directly. Works in all modern browsers (Chrome, Edge, Firefox, Safari) on both desktop and mobile.

Is my data safe when using JSON 与 CSV 互转?

Tools marked "browser-local / no upload" process your files entirely on your device. Server-side tools (e.g., PDF conversion) delete temporary files immediately after processing — no persistent storage.

Are there daily usage limits on JSON 与 CSV 互转?

Most pure-frontend tools are unlimited. Tools that consume server resources (format conversion, OCR) have a free daily quota; logging in gives you a higher quota. Check "Remaining today" at the top of the tool page for details.
