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.
