First Power Query and Power PivotNext Power BI – Power Query is the data tool and Power Pivot is the modeling tool within Power BI

While maintaining Excel-like look and featuresCan just use point-and-click and can get very advanced with powerful functions

Can import standard files as well as unformatted text files and folders (See Excelerator BI blog post “Find Duplicate Files on Your PC with Power BI” [http://exceleratorbi.com.au/find-duplicate-files-pc-power-bi/]) .

In particular Oracle, SQL Server, and SSAS.

Can access other DBs via ODBC, but also SharePoint and Exchange.Here is where Blank Query is so you can build your own query.

And there are others – From Web!

Page 10: CCPRO 2016 Power Presentation

Can use From Folder to load multiple files within one folder.

1. See the list of files per term.2. Can click Load to just load this, but typically want to click Edit to do more

transformations.

12

Page 13: CCPRO 2016 Power Presentation

Within Power Query, we can “Expand” the Binary content which are just the individual files. This is powerful!

13

Page 14: CCPRO 2016 Power Presentation

Excel is often “helpful” like this. Sometimes I keep the Changed Type step and just fix the fields it did incorrectly or prematurely.

14

Page 15: CCPRO 2016 Power Presentation

Just like that, we now have loaded many files into Power Query in just a few steps.

15

Page 16: CCPRO 2016 Power Presentation

When loading multiple CSVs, it loads the headers for each file as the file is loaded. The first one is promoted to the headers, but all the rest need to be removed.

16

Page 17: CCPRO 2016 Power Presentation

Every step is recorded and can be changed or moved.

17

Page 18: CCPRO 2016 Power Presentation

This is what was done. Now I remember!

18

Page 19: CCPRO 2016 Power Presentation

Just for simplicity sake and for example.

Page 20: CCPRO 2016 Power Presentation

Here are the fall terms (if you noticed earlier, Summer was first).

Page 21: CCPRO 2016 Power Presentation

When you close a Query, you can choose Close & Load and accept the default to load the data into a sheet and not into the data model. Here we will specify how we want to load it. This is my preference every time.

21

Page 22: CCPRO 2016 Power Presentation

Table will load the data into an Excel sheet (which is specified in the middle section).Add this to the Data Model will add it to the data model for Power Pivot to use.

22

Page 23: CCPRO 2016 Power Presentation

All done. It even tells us how many rows it loaded. This only shows if you have loaded this to a sheet or to the data model.

You can add a measure or aggregation in a pivot table, but this must be done for each pivot table and have very limited formulas.

26

Page 27: CCPRO 2016 Power Presentation

Any changes to the number or date format are lost if you remove the field or create a new pivot table.How do you count students by term and academic year in the same pivot table?

27

Page 28: CCPRO 2016 Power Presentation

28

Page 29: CCPRO 2016 Power Presentation

All of these are true of Power Pivot pivot tables with the enhancement of the formulas.

29

Page 30: CCPRO 2016 Power Presentation

These are all fixed in Power Pivot.

Features – Excel-likeRibbonFormula barData area - Column names along top with filtersMeasure areaTab at bottom is table/alias nameCharacter data is left justified, numeric is right justified

NOTE: Filtering here, unlike in Power Query, does not change the filtering in Excel. It is only available to help review the data while in Power Pivot

From Data imports from Microsoft database sources (USE POWER QUERY!)

Hey, this has functions like COUNTA. So does Excel!

33

Page 34: CCPRO 2016 Power Presentation

But Power Pivot has more powerful functions like DISTINCTCOUNT!

34

Page 35: CCPRO 2016 Power Presentation

Just like with Excel Tables, you can add additional columns. Notice the formula is just like normal Excel.

35

Page 36: CCPRO 2016 Power Presentation

We can create relationships between tables and between fields (hierarchy).

36

Page 37: CCPRO 2016 Power Presentation

Then we just insert a pivot table based on this data model.

37

Page 38: CCPRO 2016 Power Presentation

Looks just like a pivot table…almost.

38

Page 39: CCPRO 2016 Power Presentation

Notice:1. ACTIVE|ALL.2. Can add the hierarchy to the table3. Unique students…wonder what that looks like?

39

Page 40: CCPRO 2016 Power Presentation

Oooooo!I fixed the format of the numbers to include a comma separator and it shows up in the pivot table (and it will show up in all pivot tables created with this measure!).

An notice the hierarchy…

40

Page 41: CCPRO 2016 Power Presentation

We can count students by term and academic year!

41

Page 42: CCPRO 2016 Power Presentation

I can add a terms table and create a relationship between both tables. Here I added Terms from the Terms table (see the Fall/Spring under the Academic Year.

42

Page 43: CCPRO 2016 Power Presentation

You mean I don’t have to redo all those transformations next year? NOPE!

1. Regular Excel functions2. Probably one of the most useful functions for educators.3. CALCULATE:

Supercharged SUMIFSAllows filtering (IFs) on any aggregate function (imagine “MAXIFS”,

“MEDIANIFS”, etc.)4. ALL/ALLEXCEPT can be used to remove filtering to create powerful measures such as

percentages
