I am trying to better familiarize myself with REGEXs. I am attempting to get the attached dataset to show only the DATE, TAVG, TMAX and TMIN while deleting the other columns. I've been able to isolate the DATE, TAVG, TMAX and TMIN using multiple find and replaces, but eventually end up with data in the WDF5 column that match TMAXs (i.e. 90) and don't know how to delete them. I think that there is an easier way to approach this, but it hasn't dawned on me yet. The complete data set is over 15000 rows long.
