A consistent code formatter (online code beautifier) standardizes indentation, spacing, and line wrapping so teams focus on logic instead of styling. Use this formatter to quickly reflow JavaScript, JSON, HTML, and CSS for copy‑pasteable examples, clean pull requests, and approachable documentation.
What it does
Formatting applies opinionated rules across files—indentation, spaces around operators, quote style, trailing commas, and maximum line length—to produce a stable, readable layout. This makes diffs smaller and simpler, reduces subjective review comments, and speeds up onboarding for new contributors.
How to use it effectively
Paste code or upload a file, choose the language, and click Format. The parser builds an abstract syntax tree and prints it with consistent rules. Use it to polish examples, clean up snippets copied from logs, and standardize code before sharing in tickets, wikis, or slides.
Use cases and tips
For documentation, format examples to improve legibility and prevent copy/paste errors. For code review, reformat before committing to avoid noisy diffs. In CI, pair this with your project’s formatter configuration as the source of truth so automation and manual checks agree.
Consistent formatting improves readability and onboarding. Automate it to keep codebases healthy and reduce review friction.
