FAQ
What are the two merge options?
One is "merge vertically into a single table," where data from multiple files is joined end-to-end; the other is "each file as a separate sheet," where each file becomes a worksheet within one Excel file.
How are duplicate headers handled?
When merging vertically, select "keep only the first header"—subsequent files' first rows will be skipped automatically.
Can I adjust the merge order?
Yes. Use the up/down arrows in the list to reorder files—the merge will follow this sequence.
