Combine several Excel or CSV files into one — the job Power Query makes needlessly painful. Stack tables that share the same columns into a single sheet, or gather every sheet from every file into one workbook.

How to combine
Stack into one sheet
Tables share the same columns (e.g. monthly exports). Rows are appended one after another, with an optional column showing which file each row came from.
Keep sheets separate
Every sheet from every file lands in one workbook, each on its own tab. Nothing is combined — just gathered together.
