Option A: Append / Stack Sheets
Combine monthly exports (`Jan.csv`, `Feb.csv`, `Mar.csv`) even if columns are in different orders. Header alignment automatically matches columns by name and optionally adds a `Source Sheet` column.
Option B: VLOOKUP / Join Two Sheets
Select a Base sheet (`Orders_Q1`), pick a Lookup sheet (`Order_Owners`), choose the shared key (`Order ID`), and SheetCombine pulls matching status/owner columns into a fresh tab.
