Frequently Asked Questions About Replace Line Breaks

What is the difference between Replace Line Breaks and Remove Line Breaks?

Remove Line Breaks strips ALL newlines entirely. Replace Line Breaks gives you control over WHAT replaces the newlines — spaces, commas, tabs, or custom text.

Does this handle different line ending formats?

Yes. CRLF (Windows), LF (Unix/Mac), and CR (old Mac) are all detected and handled correctly.
