Power BI videos | Power BI Part 3.1 - Getting Data from Excel

Posted by Andrew Gould on 17 June 2019

Power BI Part 3.1 - Getting Data from Excel

This video shows you how to import data from Excel into a Power BI report. You'll learn about the importance of Excel tables and range names and how to select the appropriate range to import. You'll see how to import multiple tables and create one-to-many relationships between them. You'll also learn about using the Power Query Editor to clean up untidy data by deleting rows, promoting headers and altering data types. The final part of the video explains a couple of techniques for appending multiple tables into a single list, and how to merge multiple queries into a single table to make it easier to create reports.

See our full range of Power BI training resources, or test your knowledge of Power BI with one of our Power BI skills assessment tests.

Hi,

This is my first post on Power BI, so please excuse my naivety!

I have a workbook containing many formulae on a worksheet relating to other worksheets within the same workbook, eg SUMIFS, VLOOKUPS, etc.

Updating rows causes the workbook to be slow (Excel shows Calculating 1%, 2%, etc.)

My limited understanding of Power BI is that it's made for creating dashboards by clicking an dragging icons.

Would Power BI be able to solve this updating of fomulae problem?

Thanks

Not quite the first post!

Power BI will work fine until you refresh the data, at which point it will go back to the underlying Excel workbook to get the latest data. I wouldn't have thought this would trigger an Excel recalculation, however, so it should run quickly.

Thanks for your reply.

It's been so long since my "other" (I'm not certain the other was the first now!) post that I'd forgotten I've written to you in the past, :)

Hi

Having watched this video, in particular the part about merging tables, it leads me to think that it is actually doing a vlookup. Many people have expressed their desire to use Power Query to do vlookups because of its speed. My question is: how do you incorporate the vlookup performed using Power Query into VBA?

Suppose in Excel on Sheet1 column 1, I have the values 1,2,3,4,5 and in column 2 the values a,b,c,d,e.

Also on Sheet2 I have the value 1 in cell A1. Running the following simple code would return the value of "a" into cell B1 on Sheet2, as expected:

Option Explicit

Dim SourceArray() As Variant

Sub Start()
    SourceArray() = Sheet1.Cells(1, 1).CurrentRegion.Value

    Call Module1.Lookup

    Erase SourceArray()

End Sub

Sub Lookup()

    Sheet2.Cells(1, 2).Value = Application.WorksheetFunction.VLookup(Sheet2.Cells(1, 1).Value, SourceArray(), 2, False)

End Sub

My question is: if the Lookup subroutine was done manually using Power Query, how can that code be generated? As far as I'm aware, (and do correct me if I'm mistaken), clicking the macro recorder button then performing Power Query steps manually DOES NOT generate any VBA.

Thanks

I don't think Power BI supports VBA in any shape or form (others agree). I would suspect that Microsoft will never add this; they're more likely to let people automate Power BI using M, Python or C#.
