Question 1

What is Code Formatter and how does it work?

Accepted Answer

Code Formatter is a universal code beautifier that formats and indents code for better readability. It supports multiple programming languages including JavaScript, TypeScript, HTML, CSS, JSON, SQL, and XML. The tool parses your code and applies consistent formatting rules including proper indentation, line breaks, and spacing.

Question 2

Which programming languages are supported?

Accepted Answer

Our Code Formatter supports JavaScript, TypeScript, HTML, CSS, JSON, SQL, and XML. Each language has specific formatting rules tailored to its syntax. JSON formatting is always valid JSON, while other languages use intelligent parsing to determine proper structure.

Question 3

Can I customize the formatting options?

Accepted Answer

Yes! You can choose your preferred indentation style: 2 spaces or 4 spaces. The formatter will apply your chosen style consistently throughout your code. Different projects may have different style requirements, so flexibility is key.

Question 4

Does formatting change my code functionality?

Accepted Answer

No, formatting only changes whitespace, indentation, and line breaks. The actual code logic, syntax, and functionality remain exactly the same. Formatted code will behave identically to the original.

Question 5

Is my code secure when using this formatter?

Accepted Answer

Yes, absolutely. All formatting happens directly in your web browser using client-side JavaScript. Your code is never uploaded to our servers or any third-party services. This makes our tool safe to use with proprietary code, API keys, or sensitive business logic.

Question 6

Can I format minified or compressed code?

Accepted Answer

Yes! The Code Formatter can take minified, compressed, or poorly formatted code and restore it to a readable format. This is especially useful when you need to debug third-party scripts or understand obfuscated code.

Question 7

Should I format code before or after committing to version control?

Accepted Answer

Best practice is to format code before committing. Consistent formatting makes code reviews easier and keeps diffs clean. Many teams use formatters as part of their CI/CD pipeline or pre-commit hooks to ensure consistent formatting across all contributions.

Question 8

Does this tool work with code frameworks and libraries?

Accepted Answer

Yes! The formatter works with any code regardless of frameworks or libraries used. It handles React components, Vue files, Angular templates, Node.js modules, and any other JavaScript or TypeScript code. The formatter respects JSX syntax and TypeScript types.
