  Hello
  The package attached worked fine and all rows are inserted. what I am trying to do now is if a new data is added into the excel source and I run the package again only the new row is inserted into my excel destination. Thanks for your help

  One way of doing this would be to read the key data from the Excel spreadsheet into a cache transform as step 1 of your package and then use the generated cache as the source for a Conditional Split which checks incoming rows against those in the cache and discards matches.

  Thanks Phil for your reply I added the cache transform how can I specify the conditional Split.
