About this tool
Code Formatter is a free online developer tool. Format and beautify CSS/JS/SQL/XML code. Built for coders and engineers who want less friction. It runs entirely in your browser — no download or sign-up needed.
After pasting the code and selecting the language, the tool automatically formats it: uniform capitalization, align brackets, add white space, wrap around, etc. Support options such as custom indentation (2 white spaces, 4 white spaces, Tab), quote style (single quote/double quote), ending comma, etc. You can also compress the code (remove white space and comments) to reduce size.
The formatting engine uses a WebAssembly version of the formatting tool in Prettier (JavaScript/TypeScript/JSON/CSS/HTML), Black (Python) or other languages. Run on the browser side without uploading code. Supports syntax checking and prompts when errors are found.
Great for organizing copied code to make it readable, or unifying team code styles. Compression reduces the size of code used for transmission or embedding.
Code formatting tool that supports code beautification and compression in multiple languages such as JavaScript, Python, JSON, HTML, CSS, etc., and can customize creases and styles.
