In Power BI Free Service I did Get Data from a Office 365 E3 Sharepoint site to retrieve a csv file as new dataset.
I exported the dataset to Excel. It exports odc file that when I open in Excel 2013 creates new workbook, creates new pivot table with the exported dataset as source.
Problem is that none of the numerical values can be used as pivot values eg to sum, avg, etc.
I guess this is because the numerical values are strings not formatted as numbers.
However I can't see anywhere to set the data types for this dataset either in Power BI Service.
Where can I change the data types?
