One of the most sought after a query from the millions of Excel users around the world is:

How do I consolidate multiple Excel workbooks in Power Query into one?

There are a couple of ways you can do this, using VBA or complex formulas but the learning curve is steep and out of reach for most Excel users.

Luckily with Power Query Excel Workbook, this consolidation task can be done in a couple of minutes!  That’s right, only a couple of minutes.

I show you how below…

STEP 1: Create a New Folder on your Desktop or any directory and name it to whatever you like e.g. 2016 Sales

Move an Excel Workbook in this Folder that contains your Sales data e.g. January 2016.xlsx

move jan


STEP 2: Open a NEW Excel Workbook and go to Power Query > From File > From Folder

from folder


STEP 3: From the Folder dialogue box, click the Browse button

STEP 6: This will bring up the Add Custom Column dialogue box.

Put the Months in the ROWS and the Sales $ in the VALUES area:

You can move similar workbooks into the Folder we created in Step 1, say for subsequent months eg. February 2016.xlsx, March 2016.xlsx etc

NB: The Excel Workbooks have to have the same format and number of columns as in the workbook we imported in Step 1

move subsequent months


STEP 17: In your Excel workbook, click on the imported data and this will open up the Workbook Queries pane (If this does not open, go to Power Query > Show Pane)

Click the Refresh button (or you can go to Table Tools > Query > Refresh)

STEP 18: This will import the February 2016.xlsx and March 2016.xlsx data into the Excel workbook and append it to January’s data

STEP 19: Now you can Refresh the Pivot Table and the new imported data will be reflected

updated pivot


Next month all you have to do is drop in the new month’s workbook into the 2016 Sales Folder and Refresh the Query & the Pivot Table to see the results!
