What it does
Stacks the data from several worksheets into one combined table, one after another. It checks that the columns line up and stops with a clear message if they do not. The header is written once and the result goes to a cell you pick. Nothing is overwritten without asking, this runs inside Excel, and you can undo.
- Where the result goes
- The data from the selected sheets is stacked starting at the output cell you pick, with the header added once.
- Source data
- The source sheets are unchanged; undo restores the previous output values.
- Good to know
- Column count, header and order are validated; on a mismatch the run stops with the source index and reason.
