Frequently Asked Questions:
What's the difference between append and join?
Append stacks sheets vertically (one below the other), ideal when sheets have the same columns. Join combines sheets horizontally based on a common key column, like SQL joins.
Can I merge sheets with different columns?
Yes! In append mode, missing columns are filled with empty values. In join mode, you specify which columns to match on.
How do I know which sheet each row came from?
Enable "Add source sheet column" to automatically add a column tracking the original sheet name for each row.
