Transfering data to off line controller

totally new want to know how to transfer the data to off line controller, I could not see in file of off line controller (for laser sainsmart)

The GCode format saved by LightBurn is not compatible with the Sainsmart offline controller. It doesn’t like comments, and it apparently needs “windows style” line endings (\r\n) instead of Mac/Unix style (\n).

how to do window style please explain

If you download Notepad++, you can do it there (right click the bottom where it says the LF / CR type):
