I am doing something a little bit different and was wondering if you could help guide me in my use case. I have a SharePoint folder where different CSVs will be uploaded with different headers. Each csv will have at least one of the common merge headers, so there will always be "Key1", "Key2", or "Key3" as one of the headers - the rest might have extra data. I am trying to modify my power query to handle these cases, so that if the file only has "Key2" - just that column will be read in and the rest ignored. Or if it just has "Key1" and "Key2" - those will be read and the rest ignored.. etc
I created a sample file with 3 columns for the 3 keys for my default file, but I need help modifying my query because right now the new files just read the first 3 columns of data and doesn't search for "Key2" in the data. Any help on this use case?
