Text parsing and string manipulation are fundamental operations in programming and data processing. Removing specific lines from text files based on a match condition is a common need when cleaning up log files, filtering code snippets, or processing raw data sources. This tool provides a simple interface to perform this type of text filtering without installing software or registering accounts.
The algorithm iterates through each line in the input text content, checking if the line contains the specified removal text string using the String.includes() method. Lines that do not contain the removal text are added to a new array. Finally, the new array with the remaining lines is joined back into a single string value using the join() method with newline characters to recreate the multi-line text format.
