I first started this with VBA, and I have been advised to use PowerBI. However, I do not really no if my issue can be solved through powerBI.

I have a file which will be send on a recurring basis, with specific information which need to be grouped. I am trying to create a VBA macro to automate the file prepareation and make it suitable for import in another tool.

I have about 40 colomns, but sometimes less. The place of columns sometimes change, I thus cannot refer to column place (A, B, C...) I have to look for the column name.

Also, I have to look for some specific column. If these columns have data, I need to add specific element for each cases to the previously concatenated columns.

I am providing sample code below

Here is a dummy data description:

|Client| ID | Info Superman | Info Product type | Spec 1 | Spec 2 | Spec a | Spec b | Info costumer type | Info facility type | Geography |

When neither "spec 1", "spec 2", "Spec a" or "Spec b" have values I need to group data in the following way (including headers): "Client"+"Superman"+Bravo+"Info costumer type"+Info facility type" i.e ClientSpermanBravoInfo

If there is a value for Spec 1 or 2 : "Client""Superman"AlphaBravo"Info costumer type"Info facility type"

If there is a value for Spec 1 or 2 and Spec a and b: "Client""Superman"AlphaAlphaBravo"Info costumer type"Info facility type".

So far, I have the following VBA code, but using PowerBI would provide a simpler and more elegant solution. I have been looking at resources close to that one for example : https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-april-update-feature-summary/ in order to query data in specific way, and create columns based on specific conditions, but the I cannot find the solution.

If you can use a PowerQuery instead of PowerBI answer, if the data was loaded into powerquery (Data .... From Table/Rage ... [x] my table has headers) then adding a simple custom column would probably do it.

Add Column ... Custom Column ... with formula similar to below; it combines columns using the & character based on the values of other columns in that row, regardless of where those columns appear or how many columns there are

= if [Spec 1]=null and [Spec 2]=null then [Client]&" "&[ID]&" "&[Info Superman] else
if [Spec 1]<>null and [Spec 2]<>null then [Info Product type]&" "&[Info Superman] else
null

You could then use Transform ... Group By ... to group on that column, and save back to the workbook with File... Close and Load...
