    Hi IzaLeo ,

     

    It sounds like your second table is introducing duplicates into the merged table.

    Open your second table, select the column that you are matching to the first table with, go to the Home tab > Keep Rows (dropdown) > Keep Duplicates. This will show you which rows are creating the extra rows in your merged table.
