How It Works
Process JSON values locally in three simple steps.
1. Enter Data
Paste your JSON data or text into the input field. The tool automatically validates JSON format.
2. Set Key
Enter a secure secret key. This key is required to decrypt the data later, so keep it safe!
3. Encrypt/Decrypt
Encrypt or decrypt the JSON values directly in your browser, then copy the result when ready.
