Is all of your data AM, or does some of your data look like:

9:30p

In which case:

=TIMEVALUE(IF(RIGHT(A1,1)="a",SUBSTITUTE(A1,"a"," am"),SUBSTITUTE(A1,"p","
pm")))

Then change the cell format to a TIME format.

I have series of times in a column that is formatted as 9:30a, 9:40a,
etc. How do I convert these to time, i.e., 9:30 AM, etc.?
