If you are still manually opening 40 different Excel workbooks, copying ranges, and praying that the columns align, you are living in the stone age of productivity. By 2026, the conversation has shifted from "How do I merge these?" to "How do I semantically integrate these?" We no longer just stack rows; we use AI to understand that "Revenue" in File A is the same as "Total_Sales" in File B, even if the formatting is a nightmare.
