Strip Extra Spaces & Normalize Text Whitespace Remove extra whitespace — collapse multiple spaces to single spaces.

The tool works by using JavaScript's built-in String.replace() method with regular expressions to normalize whitespace in the input text. It first replaces sequences of two or more spaces with a single space using the regex / {2,}/g, effectively removing extra spaces between words and phrases. Then it replaces one or more tabs with a single space using the regex /\t+/g, ensuring that tabs are treated consistently as single spaces. This approach ensures that mixed spaces and tabs are correctly normalized to single spaces.

When the trimLines option is enabled, the tool splits the input text into lines using the newline character \n as a delimiter, trims leading and trailing whitespace from each line using String.trim(), and then joins the lines back together with newline characters in between. This process removes any extra spaces at the start or end of each line. The collapseBlankLines option works by replacing three or more consecutive newline characters with two newline characters using the regex /\n{3,}/g, effectively collapsing multiple blank lines into two.

The tool uses React's useState hook to store the state of the trimLines and collapseBlankLines options, and the useCallback hook to memoize the onProcess function so that it is only recreated when the dependencies change. This ensures that the function is not redefined unnecessarily, which can improve performance. The TextToolLayout component from the @/components/shared directory provides a standard layout for text processing tools, including input and output fields and a button to trigger the processing operation.
