Blanks showing in table visual
swb128 Hi, happy to hear you found the issue! "Power Query analyzes the example file (by default, the first file in the list) and determines the correct file connector to use to open that file."
https://learn.microsoft.com/en-us/power-query/combine-files-overview
So It builds transformation steps (like types) based solely on that file. And those steps are then applied to all other files, even if they are different or leading to missing or null values like in your ListPrice column.
I would go back and inspect csv data in excel or notepad before I load them in power query, identify one of the incorrupt ones and use it as the first file.
Not sure if there's a better or automated way. Maybe other people can advise?
Super UserHi swb128
Have you checked in Data view whether ListPrice column is not blank? It is possible that while they are in Excel, your transformations have caused this column to become blank. If it isn't blank, there may be other reasons and it would be easier for us if you provided a sample pbix (confidential data removed) so we can have a look. You may post a link to a file stored in the cloud.
