Domande frequenti

Is my JSON data sent to a server?
No. Parsing, formatting, and minifying all happen locally in your browser using standard JSON parsing — nothing is transmitted anywhere.
What happens if my JSON is invalid?
You'll see the specific parsing error message so you can locate and fix the problem in your input.
What is the difference between Format and Minify?
Format adds indentation and line breaks for readability. Minify strips all unnecessary whitespace to produce the smallest possible file size.
