My colleague and I both use Macbook Pros on the latest Mac OS.
He exports CSV files from MS Excel for Mac and sends them to me, but when I receive them I open them in a text editor and there are blank lines on every other line.
Weirdly though, when he opens the same file on his machine in the same text editor, he does not see blank lines. Which makes me wonder if this is a setting on his machine.
I know Windows and Mac treat line endings differently, but we are both on a Mac. And Sublime should be the same on both machines.
When I upload them to our linux server, linux agrees with me (our scripts see blank lines in the CSVs and have to be ignored).
He is creating CSVs using the UTF-8 format.
