The DFIU Importing tool has been very handy … but there is a learning curve … and even after all the data we have entered using this tool for our 3 stores – finally found this one ( with the help of Tier 2 help desk and a gracious lady on Tier 1 who helped push this ).
See image below ,,, this is what a line feed and a ‘line return’ look like >>> at the end of each line … to see these characters I opened up in MS Word. What is interesting after the 3rd failed attempt to import … where is says – see errors in red …press the button and no errors show ( 2nd image ) and applying a combo of =CLEAN(TRIM( data here )) it still failed. So these odd ball extra line feeds … hope I can avoid these … good luck with your experience using DFIU.
