I am downloading xlsb file from web to a databse folder using script task. I have to use that xlsb file to populate one of our table on daily refresh and load. I have tried your technique, but no luck. I don't see any sheets or data in the excel source. I have downloaded xlsb file as xlsx and I can not able to open and use it. Right now I am downloading xlsb file as xls and then open and saving the file as xlsx.When I save the xls file as xlsx the file size dramtically 3 times increased (in my case 20 MB to 66 MB). Using OLEDB Access database connection connecting to the xlsx file and populating the table. This is cumbersome. Can you suggest me a handy one for this task?
