}Frequently Asked Questions
What is a JSON Formatter?
A JSON Formatter beautifies raw JSON by adding indentation and line breaks so nested objects and arrays are easier to read and debug.
Is my JSON data safe on Neemtools?
Yes. Formatting runs entirely in your browser. Your JSON is never uploaded to our servers.
Can I format invalid JSON?
No. The tool first validates your input. If the JSON is invalid, it shows a clear error in the output panel so you can fix the syntax. Use JSON Repair for common fixes.
What is Tree view?
Tree view shows nested objects and arrays as an expandable outline with counts, so you can browse large JSON without scrolling a long text block.
Is the JSON Formatter free to use?
Yes. You can format unlimited JSON for free with no signup and no watermarks.
