Publish Excel file to PowerBI using VBA

Recently Teo Lachev released a very short but important post about Automation Excel to PowerBI publishing.

In a nutshell: now we have a VBA method PublishToPBI, which allows to publish workbooks to PowerBI.

This is quite interesting scenario for Excel-based Self-Service BI solutions.

I played around with this method, and share with you results of my experiments.

Excel VBA PublishToPBI method documentation

Unfortunately, there is no official documentation yet. At least in the list of Workbook Methods.

Below is my modest attempt.

Purpose

Publish workbook to PowerBI as a report or dataset.

Requirements

  • workbook must be saved in xlsx or xlsm format.
  • User with PowerBI license must be signed-in in Excel.
  • for publishing as a dataset – workbook must have Excel Table or Data Model.

Syntax

expression.PublishToPBI( PublishType, nameConflict, bstrGroupName )

expression a variable that represents a Workbook object.

Parameters

Name Required/Optional Data Type / Description
PublishType Optional Enum XlPublishToPBIPublishType

msoPBIExport = 0, publish workbook as a dataset. Workbook must contain Table Data (range formatted as a Table) or Data Model (aka PowerPivot model).

msoPBIUpload = 1 (default) publish workbook as a report, which can be consumed in Excel Online directly in PowerBI.

nameConflict Optional Enum XlPublishToPBINameConflictAction

msoPBIAbort = 1 (default), workbook will not be loaded to PowerBI if there already exists workbook with same full name (including extension)

msoPBIIgnore = 0, ignores existence of report / dataset and creates new one on Upload/Export.

msoPBIOverwrite = 2, overwrites existing report / dataset with same full name of workbook. Note: method raises an error if find more than one report / dataset with same full name (e.g. if msoPBIIgnore was used previously).

bstrGroupName Optional String

Name of target Workspace.

If omitted, method loads workbook to “My Workspace” of signed-in user.

Note: requires Pro-account, signed-in user must have edit rights in target workspace.

Example

' Creates Dataset from ActiveWorkbook in workspace "Finance Team" (if signed in user has access to it)
ActiveWorkbook.PublishToPBI nameConflict:=msoPBIOverwrite, bstrGroupName:="Finance Team", PublishType:=msoPBIExport
 
' Creates PowerBI Report from ActiveWorkbook in signed in user's workspace
ActiveWorkbook.PublishToPBI nameConflict:=msoPBIOverwrite, PublishType:=msoPBIUpload
 
' Creates Dataset from ActiveWorkbook in signed in user's workspace
ActiveWorkbook.PublishToPBI nameConflict:=msoPBIOverwrite, PublishType:=msoPBIExport

Shift cells up/down in same column in Power Query

In my previous post I wrote about one interesting technique used by my colleague Zoltán Kaszaki-Krsjak.

Categoty_tmp = Table.AddColumn(Buffer, "Category_tmp", each Buffer[Category]{[ID2]}?),
// It helps to shift values of column [Category] one row upwards.

It is a trick that you most probably will not use in any of your solutions. However, worth to know how it works and how to do this without adding new columns.

“each Buffer[Category]{[ID2]}?” is just a function, so we can combine it with methods described in one of my posts (Transform Column Using Custom Function).

Here is the code.

let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Duplicated Column" = Table.DuplicateColumn(Source, "Category", "Method1"),
#"Duplicated Column1" = Table.DuplicateColumn(#"Duplicated Column", "Category", "Method2"),
#"Duplicated Column2" = Table.DuplicateColumn(#"Duplicated Column1", "Category", "Method3"),
Buffer = Table.Buffer( #"Duplicated Column2" ),

Method1 = Table.FromRecords( Table.TransformRows( Buffer, each [Index = [Index],
    Category = [Category],
    Method1 = Buffer[Method1]{[Index]}?,
    Method2 = [Method2],
    Method3 = [Method3] ] ) ),

Method2 = Table.FromRecords( Table.TransformRows( Method1, (row) =>
    Record.TransformFields( row,
    {"Method2", each Buffer[Method2]{ row[Index] }? } ) ) ),
    // method offered by Miguel Escobar in comment to previous post

Method3 = Table.ReplaceValue(Method2, each [Method3], each Buffer[Method3]{[Index]}?, Replacer.ReplaceValue, {"Method3"})
in
Method3

File with methods is here.

But which method is faster?

Bar-Mekko chart in Excel with Power Query

Seems, Excel charts is an area that till now wasn’t considered in blogs as a target for Power Query application (Get & Transform in Excel 2016).

Nevertheless, PQ can replace some VBA solutions and make your workbooks macro-free.

In far 2015 my colleague Zoltán Kaszaki-Krsjak shared with me a very good example of how Power Query can help with generation of specific tables for specific charts, which are widely used in our organization.

Idea to write a blog post about this technique became dusty in me OneNote, and probably would wait more if only Jon Peltier hadn’t attracted my attention to this topic again by his recent post.

Sample workbook contains a solution for Bar-Mekko chart (or “variable width column chart”)


Such chart allows to easily see share of categories, growth or absolute value. Can be used to compare market segments or productivity of departments / subsidiaries. Red line in this case shows average growth – another small but important detail.

Interested how to build it?

Part 2: Combination of rows of tables list in Power Query

Part 1 describes approach showing how to work with List.Generate, Table.FromRecords, List CrossJoin in Get & Transform (aka Power Query, M language).

Homework is done. Advice is digested.

And I’m ready to introduce another solution to combine multiple tables rows.

It is so simple, and can be done in UI!

All regards and honor should go to Imke Feldman (http://www.thebiccountant.com/) as she found that “epic Pokemon”.

I looked at this task as a programmer, thinking about loops and iterations.

Imke – completely differently – as simple user, don’t even thinking about programming, as she said :-).

Remind, we start from four tables

And want to mix all rows to get all possible combinations (indexed).

How to do this using UI only? Continue reading

Combination of rows of tables list in Power Query

Recently I faced interesting Power Query problem. Actually, initial problem has nothing related to Power Query.

I required to export quite big volume of data from SAP BW using Business Objects Analysis addin (BO Analysis, or BOA) and save as CSV. Amount of data is literally huge, so it was impossible to export it in one query and even in 10.

I wrote a VBA macro with a loop, where each iteration had to 1) set variables and filters 2) refresh data 3) save result as csv.

So, I had to prepare set of variables and filters for each step of loop, setting filters on several dimensions.

Following four tables describe all possible filters I needed:

Unfold Child-Parent hierarchy in Power Query

In this post I consider two types of hierarchies


First table defines typical hierarchy of companies.

Usually, such hierarchy is used for financial reports to group key figures.

Most probably, we know number of hierarchy levels upfront, but not always.

Task: Expand hierarchy, automatically detect quantity of levels in resulting table using Power Query (Get & Transform) / Power BI

Stay close to scenario described in pattern: http://www.daxpatterns.com/parent-child-hierarchies/

Goal:


Second table defines substitution of products.

Case: sometimes we required to get sales history of all predecessor products and group result on Actual Product. There can be multiple substitutions, we never know amount.

Task: In this case we need to find the latest successor, Actual Product for each product in other words.

Goal:

Query folding and dynamic parameters in SQL Queries in Power Query

Before you start reading this article, I recommend you to go through very good post on Ken Puls’s blog – Pass Parameters to SQL Queries.

If it is fine for you to use native queries to database then most probably scenario described below is not so interesting for you.

Here I’ll talk about workaround allowing to use query folding and pass parameters in Power Query without building of native SQL query.

Level: intermediate

Task definition

Generate N workbooks with data models populated with limited data scope.

Then each workbook will be shared with certain group of people, that allowed to see only relevant set of data (e.g. department OPEX of particular subsidiary).

This is dictated by fact, that if you share Excel workbook with someone – user immediately has access to all info inside data model. So, I cannot create one common data model and hide slicer somewhere with activated department. I must prepare separated workbooks.

Conditions

Data: Table with millions of records in SQL database – main data source for report (query folding required for obvious reasons)

Tools: Excel + Power Query + PowerPivot

Support data: table in Excel, defining datasets – data scopes, let’s call it Control Table

Power Query: Xlsb vs Xlsx

Recently I helped my colleague with a report. The task was to consolidate data from multiple Excel files, each contains 100k-500k rows. Hence, size of each Excel file is relatively big.

I proposed to use xlsb to store those files. One file per month, report needs R24m, so 50 MB is less than 150 MB.

In the end I finished with deep analysis what is better as Excel-files database for Power Query – XLSB or XLSX.

Resume

For PQ solutions use XLSX instead of XLSB

PQ from XLSX twice faster than from XLSB

Engine handling XLSB from time to time return error – cannot read file

“UseHeaders” parameter of Excel.Workbook function works differently for xlsx and xlsb

If sheet and table names are equal in Excel workbook – Navigator generates unique name of object.

If you interested how I revealed all this – continue reading.
