Power Query - How to Change Data Source and Use Same Queries

[LadyLily]

Hello, 

I am using Power Query in Excel and I'm new to the function so apologies if this is very straightforward. I have multiple budget workbooks that have different names but the sheets are all named the same - Task 1, Task 2, Task 3 etc to Task 20.

I opened a new workbook, chose one of the budget workbooks as my data source, created a query named for each tab to clean the data in order to export it to a flat .csv file for upload into another program. 

This worked perfectly until I went to swap out the data source with a workbook with a different name. Instead of my queries for each task sheet running against the new data source, the Power Query Editor Added Task 1 (2), Task 2 (2), Task 3 (2) to my already existing list of queries. 

How do I change the data source for each of the existing queries without them duplicating? I tried to select all of my queries and change the source in the first applied step which actually worked but it only made the change on the last query in my selection. 

Is there an easier way to do this then manually going into the Source applied step for each of my 20 queries?

Thank you.

I agree with @BKirsch12 that you probably want a Folder query here. But, if that is not what you are looking for, then you could create a query that just pulls in the data and does no other steps. Then, you would create your queries and reference that query. That way, you could just change the one query and all of your other queries would be pointing to the correct data source.

Are all your spreadsheets in the same exact format?

If so, you can use the from folder, and combine all the files.
