Hi,
I'm using a folder to import files to PowerBI.
I used the information given on this forum to solve the problem of importing xlsx files
http://exceleratorbi.com.au/combine-excel-workbooks-power-query-method-2/>
My files are monthly tial balance that I saved as 20160131.xlsx, 20160229.xlsx, etc
I would like to add a new column to have the date retrieved from the file name.
I saw other way with csv files, tried it, but it's not working.
Thank you for your help
