FAQ

Does "Trim ends" work on the whole block or per line?

Per line: leading and trailing whitespace of each line is removed, while spaces inside the line are kept.

What are CRLF and LF?

Windows uses carriage return + line feed (CRLF, \r\n) as line breaks, while Unix / macOS and most code files use line feed (LF, \n). Conversion is used for cross-platform alignment.
