Frequently Asked Questions
- How do I format minified JavaScript code online?
To format minified JavaScript, paste your compressed code into our Code Formatter, select "JavaScript" from the language dropdown, and choose your indentation preference. The tool automatically adds line breaks after semicolons and braces, indents nested blocks, and formats the code for readability. This is perfect for debugging production code or understanding third-party scripts.
- What is the best way to beautify JSON for debugging API responses?
Our JSON Beautifier formats compressed JSON into readable, indented structure. Paste your API response, select "JSON" as the language, and get properly formatted output with each key-value pair on its own line. This makes it easy to inspect nested objects, find specific values, and debug API integrations. The formatter validates JSON syntax and shows errors for invalid input.
- Can I format HTML code with proper tag indentation?
Yes, our HTML Formatter properly indents nested tags for better readability. Paste your HTML, select "HTML" as the language, and the tool will place each tag on its own line with appropriate indentation based on nesting level. This is useful for cleaning up inline HTML, formatting email templates, or preparing code for documentation.
- How do I beautify CSS with organized selectors and properties?
To beautify CSS, paste your minified or messy stylesheet and select "CSS" from the language dropdown. The formatter places each selector on its own line, adds line breaks after opening braces, puts each property on a separate line with proper indentation, and ensures consistent spacing around colons. This makes stylesheets easier to read and maintain.
- Is this code formatter free to use without any limitations?
Yes, our Code Formatter is completely free with no usage limits, no signup required, and no file size restrictions. The tool runs entirely in your browser, so your code never leaves your computer. You can format as many files as you need, making it perfect for daily development work, code reviews, and documentation preparation.
- What indent size should I use for formatting code?
The choice between 2 spaces, 4 spaces, or tabs depends on your project standards. 2 spaces is common in JavaScript/React projects and saves horizontal space. 4 spaces is traditional in Python and Java. Tabs allow each developer to set their preferred visual width. Our formatter supports all three options - choose what matches your team coding style guide.
