Frequently Asked Questions
Why should I format my code?
Formatted code is easier to read, maintain, and debug. Consistent formatting helps teams collaborate effectively, reduces errors during code reviews, and makes it easier to spot bugs. Most professional projects require code to follow style guidelines before merging.
What formatting standards do you support?
Our formatters follow industry-standard style guides: PEP 8 for Python, PSR-12 for PHP, Google Style for C/C++, and Prettier-compatible formatting for JavaScript/JSON/YAML. Each formatter applies language-specific conventions for indentation, spacing, and line breaks.
Is my code secure when using formatters?
Yes, all formatting happens directly in your browser using JavaScript. Your code never leaves your device or gets sent to any server. This makes our formatters safe for proprietary code, credentials, and sensitive data.
Can I customize the formatting options?
Many of our formatters support customization including indent size (2 or 4 spaces vs tabs), line width limits, brace styles, and quote preferences. Advanced options are available on individual formatter pages.
What is the difference between formatting and minifying?
Formatting adds whitespace, indentation, and line breaks to make code readable. Minifying removes all unnecessary whitespace to reduce file size for production deployment. We offer both options - formatters for development and minifiers for production.
Do formatters change my code logic?
No, formatters only change whitespace, indentation, and line breaks. They never modify your code logic, variable names, or functionality. The formatted code is functionally identical to the original - just easier to read.
