Code Formatter & Beautifier — Supported Languages

Our code formatter supports six of the most commonly used web development languages: JSON, HTML, CSS, JavaScript, SQL, and XML. It beautifies (adds indentation and line breaks) and can also minify (remove all unnecessary whitespace) your code. All processing happens in your browser — no code is ever sent to a server.

How to Format Code

  1. Select your language tab (JSON, HTML, CSS, JavaScript, SQL, or XML).
  2. Paste your code into the left panel.
  3. Choose indent style (2 spaces, 4 spaces, or tab) and optional minify.
  4. Click Format Code. The formatted output appears in the right panel.
  5. Copy or download the result.

Frequently Asked Questions
