FAQ

Does formatting change my data?
No, formatting only changes whitespace. Your data remains exactly the same, just easier to read.
What is JSON minification used for?
Minified JSON is smaller, making it faster to transfer over networks. It's commonly used in production environments and APIs.
Is my data sent to a server?
No, all processing happens locally in your browser using JavaScript. Your data never leaves your device.
