What is JSON Beautifier?

A JSON Beautifier is an online tool that takes minified or unformatted JSON data and restructures it into a human-readable format with proper indentation and line breaks, making it easier to read and debug.

Is my JSON data secure?

Yes, your JSON data is secure. The processing for this JSON Beautifier tool happens entirely in your browser, meaning your data is not sent to our servers. Your privacy is our top priority.

Can it validate JSON?

While its primary function is beautification, the tool will indicate if the JSON input is invalid by displaying an error message instead of formatted output, indirectly serving as a basic JSON validator.

Is there a limit to JSON data size?

As the processing happens client-side, the limit is primarily constrained by your browser's memory and performance. For very large JSON files, you might experience slower processing.
