I have a formula in Excel that I would like to autofill to 999,999 other cells. How can I do this without dragging the autofill handle down the entire sheet?
The key is to select all the cells from the one that has the formula all the way down and then fill down the formula. These steps do that quickly:
Select the cell with the formula, then while holding down the Shift key, press the End key and then press the down arrow; now release the Shift key. This will resize the selection to include the blank cells below the active cell; if all cells below are blank, it will resize the selection all the way to the end of the sheet.
Once the range is selected, press Ctrl-D to fill down the formula.
