What Is a JSON Beautifier?

A JSON beautifier re-indents JSON for readability, just like a formatter, but with more control over the indentation style — including using tabs instead of spaces, which some codebases and editor configurations specifically require.

Use this instead of the JSON Formatter whenever your project's style guide calls for tab indentation, or when you want to quickly compare how the same JSON looks at different indent widths.

You'll see a clear error message instead of a beautified result.

No — beautifying happens entirely in your browser.

A tab is a single character, so tab-indented JSON is often smaller than space-indented JSON at an equivalent visual width.
