Convert time to Half Hour inverval
I have a list of date/time values which I plan to use textto columns to
strip away the time. Next, I need to convert these time values into half hour interval values but don't know how to do this. For example Original Value Converted Value 23:16 23:00 09:56 09:30 So, you can see I'm converting the time to the last half hour that passed. Can anyone suggest a formula or method to simplify this for me? Many thanks in advance for any assistance.
