Hi Techies, I got an issue so need your advice here. I have created a report in Report Studio and it's having 2 columns which are having long text as a value (BLOB data type). Report is displaying entire text items in HTML format, but when I'm exporting it into EXCEL it's give me ##########. How to correct (wrap) it in Excel? so when end users they are directly running that report in Excel so instead of seeing ######### for long text items they should see the entire text items in those columns. Please advice!
