When you have multiple tables with inconsistent field names (column names, or header names), an append (combine) does not provide a proper table with records: instead, you get many null values mixed in with record values. This video teaches how to fix this problem. We see how to solve the problem when you have CSV text file tables or when you have proper tables, like an Excel Table.

In this video learn what to do when you append tables and the result yields many null values.
