If you would like a column of evenly-spaced values, such as for frequency bins, Excel can fill them in for you. Put the first two values in and highlight those two cells. Click on the lower right-hand corner and drag downward; Excel will continue the pattern you began.
Now insert a column just after this column to hold the actual date for use in calculations. Let's say the eight-digit dates were in column A, starting in cell A2. Then you would enter this formula in cell B2 and copy it down the whole column: =DATE(MOD(A2, 10000), TRUNC(A2 / 1000000), MOD(TRUNC(A2 / 10000), 100)) .onfiguring Excel to display date and time digits that you've entered without punctuation is a simple matter of defining the correct custom format. However, changing the formatting doesn't change the actual data. Even when you see 08/21/2007 displayed, Excel will still treat the data as the number 8,212,007.
