Hi Xiage,

I'm using the Office template without problems.
Can you check the following:

1- Do you have the binary document returned by the "HttpBinaryGet"?
Option: You have other option to get the binary document using the Service Studio.

2- Do you have elements (list values) being added to the list?
You can check it by doing debug at the action XL_AddColumns.
