Power Query Merge Issue - Duplicate Tables After Refresh?

Our take

In this discussion, we'll address a common challenge faced when using Power Query to merge tables from two Excel sheets. After merging, users often find that the original tables are duplicated upon refresh, leading to confusion about managing updates effectively. Key questions arise: Will the merged query automatically reflect changes made to the original sheets? Is it typical for Power Query to create duplicate tables during this process?

Hi everyone,

I have two Excel sheets, each containing a table. I’m using Power Query to merge them into a new table (Merge query), and everything works fine initially.

However, after I load the result back into Excel, I notice something odd:

The merged sheet (called "Merge") is created correctly.

But the original two sheets seem to get duplicated again as separate tables (like "Table1" and "Table2").

My main concern is this:

I regularly update the data in the original two sheets.

So my questions are:

Will the merged query automatically reflect updates from the original sheets when I refresh and where to but the new data in the orginal sheets or the new table 1 and table 2?

Or do I need to set up something specific to make sure the merge stays updated?

Also, is it normal for Power Query to create duplicate tables when loading, or am I doing something wrong?

Any clarification would really help. Thanks!
