>> I'm coding in Windows (Windows 10) and trying to change a Windows created text file that ends in CRLF to just LF, so that I can upload the file and process it on a Unix-based site.

If you are running the script in Windows, it will happen since when you open for write (without binmode or :raw or :unix), Perl will perform '\n' to (Windows) platform '\r\n'.
