I am trying to download a .xlsx excel file from FTP server and save it in a .csv file format. I was able to download a file from server using ftp task in SSIS and save it in a local folder now I want to save that file as csv file format for import process. I could not find a conversion method or task from .xlxs to csv. i tried script task but it didn't work. can someone please help.
You can add a Script task to achieve this, and inside the script you can use Interop Library:
The simplest way to do that will be to use an Excel source and a Flat File Destination (set it as a CSV). Hope it helps.
