I've a sheet with - among others - two columns containing:

Column A. Time figures (03:27) and
Column B. The "AM" or "PM" designator (text)

I want to be able to sort the times in chronological order, by using the
24-hour time format.

How can I tell Excel to look at the contents of the two cells in these
columns for each of the 1200+ rows in my sheet, and convert any "PM" times
to the 24-hour format?

For example, for 03:27 PM, I want the "03:27" to read "15:27".

Or is there another way to accomplish this?

Thanks!
