Hi,
almost any migrating tool can do the task in two steps. First pick the relevant data to one table and then to the second table.
For example, you can use one INSERT query which select from OPENROWSET that read the data directly from the Excel file and in the query you can get only the relevant columns for this table and manipulate the data as needed in the query itself.
In this document you have a list of tools which you can use for the task. The basic point in your case, is that you should import to each table separately. Simply read the doc, select the solution fits you and do it twice.
