Edit and preserve column headers in connected table

[jokrra89]

Hi,

I have an issue with changing column headers in a table in Excel.
after reading this Design refreshable reports in Excel with Power BI data - Power BI | Microsoft Learn

I found this to be a good approach for combining Power BI data in an Excel table.

The article states that you can customize the table and that the formatting will be preserved when I refresh data.
This does not work for me.

I tried the solution from @lbendlin in this post Solved: How to remove the table name in column headers in ... - Microsoft Fabric Community

But from my understanding, this requires the main table to be present in the Excel file. Leading to duplicate data.

Can anyone help me with this?

Best regards

Hi @v-mdharahman,
My issue is not really resolved, but @lbendlin helped clarify that his solutions is related to SSAS cube. 

My issue is related to Power BI Semantic model connection (XMLA) , and from the article by Microsoft
Design refreshable reports in Excel with Power BI data - Power BI | Microsoft Learn 
shows an example where you can change the column headers, and it should be preserved.

If anyone has a solution/clarification to this, it would be highly appreciated.

Best regards

I tried the solution from the post I referred to. 

Then I am able to remove the table name and the square brackets from the column name:

This is achievable using the M statement you provided:

let
Source = Excel.CurrentWorkbook(){[Name="Table_ExternalData_1"]}[Content],
Res = Table.TransformColumnNames(Source,each if Text.End(_,1)= "]" then let p=Text.PositionOf(_,"[") in Text.Range(_,p+1,Text.Length(_)-p-2) else _ )
in
Res

But for this to work, It needs to reference the table in the current workbook.

So, If I want to make this file refreshable, I need to keep both tables in the file, to be able to reference it in power query?

[lbendlin]

not sure what "both tables"  means here. It's a single query that has transforms applied to it.  Please elaborate.

[jokrra89]

I am connecting to a Power BI semantic model through Excel.
Then I run a Dax query to get a table into Excel.

This creates a table named Table_ExternalData_1. We can call this table nr 1

Then, using your trick, 
I create a blank query in power query, and Load to Excel.

This creates a table named Query1.
This we can call Table nr 2.

When I refresh the data, Table nr 1 needs to exist in the file for Table 2 to be updated. If i delete Table nr 1, then Table nr 2 will be empty.

[lbendlin]

Ah, you don't need Table_ExternalData_1.  In Excel you can choose to create queries that do not materialize into tables.  You can then decide later to create a table from the (now modified) query.

Look at the Table Source for Table Nr2.  It has a reference that you need to change.

[jokrra89]

Table_ExternalData_1 is not visible in Power Query, as it comes from a connection.
I am not sure about the correct Naming, but I guess from 
Design refreshable reports in Excel with Power BI data - Power BI | Microsoft Learn
that the Power BI data is connected via the XMLA endpoint.

[lbendlin]

You need to distinguish between two scenarios

#1  Run a DAX query against a semantic model.  For that you connect to "Power BI Semantic Model".  You won't be able to change/remove the table names

#2 Import data from a SSAS cube ("Analysis Services Database"), by specifying the same DAX query.  This will result in a Power Query connection where you can then add steps to remove the table names and do other manipulations.

[jokrra89]

Hi,
Thanks for the clarification. 
I am using approach #1
A combination of hacks make it possible to remove the table names:
Define column names in a selectcolumns statement in the DAX query, 
use you Power Query approach to remove "[ ]".

My question is if there should be a native solution.

according to 
Design refreshable reports in Excel with Power BI data - Power BI | Microsoft Learn

Which refers to #1 

Anyway, thank you for your insight

Please elaborate.  Can you show an example?
