Back to the tool

What is a code beautifier?

A beautifier (formatter) re-indents code and adds line breaks so it is easy to read, without changing what the code does.

Can it un-minify JavaScript?

Yes. It restores line breaks and indentation. Variable names that were shortened during minification cannot be restored.

Which SQL dialects are supported?

Standard SQL, MySQL, MariaDB, PostgreSQL, SQL Server (T-SQL), SQLite, BigQuery, Oracle PL/SQL and more.

Does it fix errors in my code?

No. It only formats. Broken code may still be formatted, but errors are not fixed.

Is my code uploaded?

No. All formatting runs locally in your browser.
