What is AutoFilter?

AutoFilter adds dropdown arrows to your header row, letting you instantly show only rows that match specific criteria — hiding all non-matching rows without deleting them.

  • Enable: Data tab → Filter (or Ctrl + Shift + L)
  • Dropdown arrows appear on each column header
  • Multiple filters can be active simultaneously across columns
  • Clear all filters: Data tab → Clear (or Ctrl + Shift + L to toggle off)

Key Insight: AutoFilter hides rows — it does NOT delete them. A row count mismatch (e.g., row numbers jump from 5 to 9) indicates an active filter. Always clear filters before sharing files!
