About the Whitespace Cleaner
A Whitespace & Formatting Cleaner is a simple but powerful utility that helps enforce a consistent coding style by cleaning up common whitespace issues. It's perfect for tidying up code snippets, preparing code for sharing, or standardizing files from different contributors.
Common Use Cases
Code Standardization
Ensure code from multiple developers adheres to a consistent style guide before merging it into a shared repository.
Improving Readability
Clean up messy or poorly formatted code to make it easier to read, understand, and maintain.
Preparing for Minification
Remove unnecessary whitespace to reduce file size before running a minifier for production deployment.
Pasting from External Sources
Fix formatting issues when pasting code from websites, documents, or emails that may have inconsistent whitespace.
Example of Cleaning:
Input:
function hello() {
console.log("Hello, World!");
}
Output:
function hello() {
console.log("Hello, World!");
}Frequently Asked Questions
What whitespace issues does this tool fix?
This tool is designed to fix the most common whitespace problems: it removes all trailing spaces from the end of lines, converts indentation from tabs to spaces (2 spaces per tab), and collapses multiple consecutive blank lines into a single blank line.
Is this tool a replacement for Prettier or other advanced formatters?
No. This is a simple whitespace cleaner, not a full-fledged code formatter. It does not reformat code according to complex rules or language-specific style guides. For comprehensive code formatting, we recommend using a dedicated tool like Prettier or ESLint.
What do you mean by 'normalized indentation'?
This tool converts all tab characters (\t) at the beginning of lines to a consistent number of spaces (in this case, 2 spaces). It doesn't re-calculate the correct indentation level for each line of code; it only ensures that the existing indentation uses spaces instead of tabs.
Does the language selector affect the cleaning process?
No, the cleaning logic is language-agnostic. The language selector is only used for syntax highlighting in the output pane to improve readability.
Is my code secure?
Yes, all processing is done client-side in your browser. Your code is never sent to our servers, ensuring complete privacy and security.
