Frequently Asked Questions
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.
