About the Code Beautifier

This code beautifier formats JavaScript, TypeScript, HTML, CSS, JSON, SQL and XML with consistent indentation. One tool for whichever language you happen to have, rather than a separate page for each.

A code beautifier is most valuable on code you did not write. A minified bundle, a snippet pasted from a ticket, a query logged by an ORM, or a file from a project with no shared style — all far easier to reason about once indented consistently.

Several languages in one place matters in practice, because the file you are staring at is rarely the one you expected. Debugging usually means jumping between a stack trace, a stylesheet, a query and a config file within a few minutes.

Formatting changes only whitespace, never behaviour, so it is always safe to run. For your own projects a formatter wired into your editor is the right answer since it enforces one shared style; this is for the one-off file and the machine that is not yours.

How to use the Code Beautifier

  1. Pick the language. Choose JavaScript, TypeScript, HTML, CSS, JSON, SQL or XML.
  2. Paste your code. Enter the minified or inconsistent source.
  3. Beautify. Consistent indentation and line breaks are applied.
  4. Copy the result. Take the formatted code.

Frequently asked questions

Which languages are supported?

JavaScript, TypeScript, HTML, CSS, JSON, SQL and XML.

Does beautifying change how my code runs?

No. Only whitespace and line breaks change, so behaviour is identical.

Can it recover original variable names from minified code?

No. A minifier discards them permanently. Beautifying restores structure, not naming.

Should I use this instead of a formatter in my editor?

For your own projects use an editor formatter so the whole team shares one style. This suits one-off files.

Is my code uploaded?

No. Formatting happens entirely in your browser.
