How to combine 2 tables with different column names and multiple duplicate rows

[TTL]

Hello all,

Just starting with Power tools and I'm trying to combine 2 tables with power query/pivot. One table have about 10 columns and the other have about 25 columns. The column names are all different but I can manually change the names to match and delete the extra columns. The columns also have duplicate/multiple rows as it is test data for same sample but at different time/ different samples but at same time (for example, various combinations of test sample 1, 2, 3, etc with test data at day 1, 2, 3, etc.).

Thank you!

Hi @TTL 

Depends how you want to combine them.

If you are happy to rename columns so they match in both tables, and delete columns so that you have the same number in both tables, then you can Append the tables into one.  Go to Home tab->Append Queries.

That will preserve all rows from both tables but obviously not all columns.

If you want to preserve all columns but not necessarily all rows, then you can Merge the tables but you need at least 1 column in each table that can be matched to each other.

From there you can do more cleaning up but without seeing the data it's hard to say more.
