Does this tool send my code to a server?

No. All formatting is performed entirely in your browser using JavaScript. Your code never leaves your device — there is no server processing, no logging, and no data storage of any kind.

What languages does the Code Beautifier support?

The tool supports JavaScript, TypeScript, Python, CSS, HTML, SQL, XML, JSON, and Markdown. Each language has a dedicated formatter tailored to its syntax and common style conventions.

Can I use this to format TypeScript code?

Yes. The JavaScript/TypeScript tab handles both .js and .ts files. The formatter handles common TypeScript patterns including type annotations, interfaces, and generics. It is a rule-based formatter rather than a full compiler, so very advanced edge cases may need manual adjustment.

What Python formatting rules are applied?

The Python formatter normalises indentation to 4 spaces per level (PEP 8), converts tabs to spaces, removes trailing whitespace from each line, adds a blank line before top-level def and class definitions, and optionally normalises string quote style between single and double quotes.

How does the SQL formatter work?

The SQL formatter uppercases all standard keywords (SELECT, FROM, WHERE, JOIN, GROUP BY, ORDER BY, etc.), places each major clause on a new line, and indents the column list after SELECT for readability. It works with SELECT, INSERT, UPDATE, DELETE, and DDL statements.

What is the difference between Beautify and Minify?

Beautify adds whitespace, line breaks, and indentation to make code human-readable. Minify does the opposite — it removes all unnecessary whitespace, comments, and formatting to reduce file size. Minify is available for JavaScript, CSS, HTML, JSON, and XML.

What does the Diff View show?

Diff View compares your original input with the formatted output line by line. Lines that were added or changed are highlighted in green, and lines that were removed are highlighted in red. This makes it easy to see exactly what the formatter changed.

How do I download the formatted code?

Click the "Download" button below the output panel. The file will be saved with an appropriate extension for the selected language (e.g. .js, .py, .css, .html, .sql, .xml, .json, .md). The filename is based on the language slug.
