Frequently Asked Questions
Will my code be sent to a server for formatting?
No. All reformatting logic happens locally in your browser. This makes CosmoxHub the most secure choice for formatting sensitive proprietary code.
Does it support TypeScript or SCSS?
Yes! Our JavaScript parser handles TypeScript syntax seamlessly, and our CSS engine is highly effective for SCSS and Less structures.
Can it fix syntax errors?
This is a beautifier, not a linter. It focuses on physical structure and indentation. It will format valid code perfectly but may not correct logical syntax errors.
