Ditched multiple Excel worksheets for one dynamic report and saved myself a ton of work

The article explains how to replace multiple similar Excel worksheets with one dynamic report, cutting repetitive maintenance. Rather than duplicating a report for each region (North, East, South, West) and updating formatting or added columns across all copies, the writer uses a single FILTER-driven layout controlled by a dropdown selection. The approach relies on structuring source data as an Excel table (using Ctrl+T) with a Region column, enabling structured references such as tblSales[Region]. For the selector, it adds data validation to a cell (example: B3) using either direct column ranges or a named range via Name Manager; if needed, UNIQUE generates a list of distinct regions. The goal is one report to manage instead of several.
