The Filter guide
Click a cell in your list and press Ctrl+Shift+L (⌘⇧F on a Mac), or Data → Filter. Arrows appear in the header row; pick the values to keep and Excel hides the other rows without deleting them.
Filter in three steps
- Click any cell in the list (or select the whole list, see below).
- Press Ctrl+Shift+L, or Data → Filter. Each header cell gets an arrow.
- Open the arrow in the column you care about, untick (Select All), tick the values to keep and press OK.
Hidden rows are still there: totals made with SUM still count them. Press the shortcut again to turn the filter off and show everything.
The empty-row trap
With one cell selected, Excel filters the "current region": the block of filled cells around it. An empty row ends that block. In a list with a gap at row 9, the filter covers rows 1 to 8 only, and everything below the gap stays visible whatever you pick. It looks filtered at a glance, which is why it gets missed.
The fix: before turning the filter on, select the whole list, header to last row (Ctrl+Shift+↓ helps, pressed until it reaches the end). Or delete the empty row if it shouldn't be there.
Filtering by more than one thing
Filters add up: filter Region to North, then Rep to Lena, and you see Lena's North orders. A column with an active filter shows a funnel on its arrow. Data → Clear removes every filter at once.
Count what's left
SUBTOTAL(103, A2:A16) counts only the visible rows and SUBTOTAL(109, D2:D16) adds only the visible amounts, so a total under the list follows the filter. Excel's status bar also shows "X of Y records found".
FAQ
- What is the shortcut for filter in Excel?
- Ctrl+Shift+L on Windows turns the filter on and off. On a Mac it is Cmd+Shift+F. Alt+Down Arrow opens the filter menu of the selected header cell.
- Why is my Excel filter not working on all rows?
- There is probably an empty row in the list: the filter stops there. Turn it off, select the whole list from the header to the last row, and turn it on again.
- Does filtering delete rows?
- No. Filtered rows are hidden, not deleted. Turn the filter off, or choose (Select All), to see them again.
- How do I sum only the filtered rows?
- Use SUBTOTAL(109, range) or AGGREGATE(9, 5, range). SUM adds the hidden rows too.
