Hi friends
I have around 5 files each in two folders in excel. I may get more files in future. The files are of same nature.
I have to combine files from each of the folder.
I have two options:
1. I create a query for one file in a folder. Duplicate queries and change the data source/name. Append queries.
2. Get data from folder.
Which is the best option in terms of efficiency?
Personally I am not in favour of get data from folder, as it creates additional queries like sample file, transformation etc., which makes the query list clumsy. But I don't want to compromise on efficiency as I will get more files in future.
I request experts to suggest.
Thanks....Thulasiraman
Hi MJ,
Someone else asked this the other day. In Power Query you cannot establish whether a process is more or less efficient based on the number of queries or steps in a query. I agree, the From Folder connector creates a load of additional queries, but then so does creating a separate query for each file and then appending them.
You'd have to do some timed tests on your data to see if one is faster/slower than the other and I'm not aware of anyone who has done this. If I were you, I'd use From Folder as this is less work to set up.

Thanks for your suggestion Mynda.
Still I am little bit jittery in using From Folder, as I encountered few problems in the past when the sheet name changes, etc
I will try and learn that way as you said it is easier to set up.
Thanks a lot.
