I'm trying to merge 2 tables and my goal is to keep everything from the firt one, and match the second. But, when I do that, i go from 3114 rows to 3123 and it's not supost to, since I choose the left outer joint. Can someone help me , please ?

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.
