Power Query should be able to extract from an xls file. What happens when you try it?
Excel 2016. When I copy excel files of both format i.e., "xlsx" and "xls" in a specific folder, then only the data of "xlsx" file is updated in table in a worksheet. While the data of "xls" file is ignored without any indication. After converting the "xls" file to "xlsx" through "Save As", its data is also updated and included in above mentioned table. Hope I have explained correctly.Which version of Power Query are you using and what specifically do you mean by "does not load in table"?
No it is set for both format. A message is received "DataFormatError: External table is not in expected format".Power Query should be able to extract from an xls file. What happens when you try it?
