There are (at least) two ways you could go about it, seeing that the column structure is identical in the two files.

You could use a Read Range activity on the source Excel file to copy, and an Append Range activity on the destination file. Both of these activities need to be in an Excel Process Scope container.

• Read Range

• Append Range

• Excel Process Scope

Another way to go about it could be to read both Excel files (Read Range) and use a Merge Data Table activity to merge the two, before using a Write Range activity to write the entirety back to the destination file.

• Merge Data Table

• Write Range/Write DataTable to Excel
