Code formatting
Provide local formatting entry points for C/C++/C#/Java/PHP/Python, JavaScript, JSON, CSS, HTML, XML, Markdown, and YAML in one place.
How to use the code formatter
Code and file names are processed only by the local formatter in the current browser; they are not uploaded, API is not called, and nothing is written to persistent storage.
Select language
Select C/C++/C#/Java/PHP/Python or another supported programming language.
Enter source code
Paste source code or open local text, choose indentation, line-break, and formatting options, then run.
Check differences
Review syntax errors and formatting results, then run it repeatedly to confirm idempotence before copying or downloading.
Limitations and Notes
- The language formatter runs using a fixed local version and does not replace a compiler, static analyzer, or code review.
- Invalid syntax, oversized files, or missing plugins fail explicitly; a generic indenter is not used to fabricate results.
- Formatting configurations may differ between projects; before release, review them against the repository’s lint and formatter configurations.
FAQ
Does formatting use a network connection?

Why does the formatting result differ from the project?
Check the language version, project configuration, and indentation options; the page uses fixed local configuration.
Will formatting modify the original file?
No. The page only generates results for copying or downloading.
