Answer :

The best method to consolidate 3 workbooks from 3 branch offices into one regional workbook is by using Excel's Power Query feature. Power Query allows you to connect to multiple data sources, merge data, and transform it as needed. Here's a step-by-step process: n1. Open a new Excel workbook to serve as the regional workbook.

2. Go to the "Data" tab, click "Get Data," and choose "From File" > "From Workbook." Browse and select the first branch office workbook. Click "Import." 3. In the "Navigator" window, select the desired data (e.g., worksheet or table) and click "Transform Data" to open Power Query Editor. 4. Perform any necessary data transformations (e.g., removing columns, renaming fields, etc.). Once complete, click "Close & Load" to load the data into the regional workbook. 5. Repeat steps 2-4 for the other two branch office workbooks. In Power Query Editor, click "Append Queries" to combine the data from all 3 workbooks.

6. After appending the data, perform any additional transformations or calculations as needed, and click "Close & Load" to update the regional workbook with the consolidated data. 7. Save the regional workbook to store the consolidated data from all three branch offices. By using Power Query, you can efficiently consolidate multiple workbooks into one, while also ensuring data consistency and reducing manual errors. This method also enables easy updates, as any changes in the branch office workbooks can be easily refreshed in the regional workbook.
