=RIGHT(C11,3)
Where C11 is the cell to check and retrive the last 10 from, in this example, we are only getting the last three(3). ONce you have made the calculation work in one cell, click it, drag it for the whole column, and check to see that the formula is correct in all places. If you do the first 2 cells, Excel will complete the rest with a drag of cells.
If you really want "records", then you should be using a DB and not a spreadsheet.
