Frequently Asked Questions
Is my JSON data secure?
Yes, all processing happens locally in your browser. Your JSON data is never sent to our servers.
What is the difference between Beautify and Minify?
Beautify adds indentation and line breaks to make JSON human-readable. Minify removes all unnecessary whitespace to create the smallest possible file size for transmission.
Can I edit the JSON in the output?
Currently, the output views are read-only for inspection and copying. You can copy the result, paste it back into the input, make changes, and format it again.
