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.

팁
Use Tabs for Accessibility-Friendly Indentation
Tabs let each developer set their own preferred indent width in their editor.
Stick to One Style Per Project
Consistent indentation across a codebase makes diffs easier to read.
