Power Query Append Tables

[JajatiDev]

Hi,

I have 3 Excel tables in 3 sheets of the workbook that are appended to create a master table. However, I'm facing an issue where the same data keeps getting appended if the refresh button is pressed more than once. Please advise how can I prevent the master table from getting appended again and again with the same dataset.

Regards,

Dev

Hi @JajatiDev ,

1. Check if your final query is included in the append: If your final query is included in the append, it might be getting loaded into Power Query again, causing duplication.

2. Use 'Append Queries as New': Go to 'Edit Queries' and select your first query then go to 'Home > Append Queries as New'. Choose your 3 tables (Query1 , Query2 and Query3) and hit OK. This should exactly append the two queries, without repeating any duplicates.
