Frequently asked questions
What does a JSON formatter do?
It adds consistent indentation and line breaks so nested objects and arrays are easier to read.
Is my JSON uploaded or stored?
No. All parsing and formatting happens in your browser. Deskutil never receives the content.
How do I fix invalid JSON?
Choose Validate to see the browser’s parsing error. Check for missing double quotes, trailing commas, or unmatched braces and brackets.
What is minified JSON?
Minified JSON removes unnecessary whitespace while keeping the exact same data structure.
