Is my data safe?
Yes. All processing uses native JSON.parse and JSON.stringify in your browser. No data is ever sent to a server.
What is the difference between Format, Validate, and Minify?
Format adds indentation (2 spaces) to make JSON readable. Validate checks if JSON is valid and normalizes it. Minify removes all unnecessary whitespace to reduce size.
