CSS, HTML and SQL Formatter

You pick the language — CSS, HTML or SQL — paste the code into the input field and click format. The tool reorganizes the text with proper indentation and line breaks, making the structure clear and easy to read, without changing what the code does.

Each language has its own conventions, and the formatting respects them: in CSS, each property gets its own line; in HTML, nested tags are indented according to the hierarchy; in SQL, the main clauses (SELECT, FROM, WHERE) are aligned to make long queries easier to read.

The result is ready to copy. All processing happens in your browser, with libraries loaded only when you use the tool — which keeps the page light and your code on your device.

Well-formatted code is easier to read, review and maintain. In practice, many people receive or generate "minified" or messy code — everything on one line, no spacing — and need to tidy it up to understand it. Formatting fixes that in a click.

It's useful when inheriting an old, unstandardized CSS file, when pasting HTML generated by some tool, or when working with a long SQL query that arrived all on one line and became impossible to read. Students use it to make their exercises presentable; professionals, to standardize code before sharing or reviewing. Whenever readability matters, formatting helps.

The most common mistake is choosing the wrong language for the pasted code. Formatting SQL as if it were CSS won't work well — each formatter understands the specific structure of its language. Check that the selected language matches the code before formatting.

Another point is confusing formatting with fixing. The tool organizes the code, but it doesn't repair syntax errors or check whether it's correct. A CSS file with a missing brace still has the error after formatting; formatting only handles appearance.

It's also worth remembering that formatting isn't the same as minifying. Formatting makes the code readable, with spaces and breaks; minifying does the opposite, compressing everything to reduce size. They're opposite goals, each for a different moment in the work.
