|  | If your spread sheet is missing the leading zero in the number, here is a quick way to fix it: 
	Make the column (for example column B) that contains the numbers without the leading zero to be "text" or "general" format.Go to a cell at in the same row as the first number in the list but in an adjacent column (for example cell C2).In cell C2, enter this formula: =Concatenate(0,B2)Copy that formula down column C for the entire length of the list of number. Column C should now contain the entire list with the leading zero added on at the beginning. Remember: Do this step in the Excel workbook before you convert the file to CSV. |
