About Newline and Line Ending Fixer
Newline and Line Ending Fixer is used to normalize line endings between Unix (LF), Windows (CRLF), and old Mac (CR) formats, preventing hidden whitespace issues in code and data files. It scans the file for mixed or incorrect line endings and converts all of them to the target format you choose. Mixed line endings in code files cause noisy git diffs — add a .gitattributes file to enforce consistent line endings across your team. Newline and Line Ending Fixer runs free in your browser at abovetool.com — no signup required.
