How do I edit my longitudinal coordinates to display in the western hemisphere on my map?

How do I edit longitudinal data before adding my XY corridantes?

Hi Ben,

What's the format of your current coordinates? And is this Map or Pro?

I think there's several parsers nowadays, and pro probably does it for you, cooks dinner then washes up... Might use it one day.

If not, decimal degrees - positive for Eastern, negative for Western will always be a winner.
