I have 2 columns of information on an excel spreadsheet. One has dates, the other time. I need to combine them so that they're in one column. Ex: 5/5/2010 0:12:25 and the cell below 5/5/2010 0:15:34, etc... Manually copy/pasting would be hell since I have 10,000 plus cells. All ideas are welcome, thanks so much!
