Convert Excel Text string to Time
I must enter appointment times in a workbook.
For instance I have cell E2 to input the time. I'll input, lets say 1500. How can I change 1500 to 15:00.
I have tried several =TIMEVALUE() statements I have found but when I put in the string 1500 or similar, the result that appears in the cell is 0:00 and the formula bar shows current date and time.
