Multiple Power Queries using same Source File

User1 has ExcelFile1 open. It uses PowerQuery to access SourceFile1.
User2 has ExcelFile2 open. It uses PowerQuery to also access SourceFile1.
SourceFile1 is a csv file, not saved as read-only.

What happens when both users refresh their queries simultaneously and try to access the same source file? Will there be a conflict/error, and if so, is there any solution to avoid this?

Thanks.

Power Query read the csv file not write back so there shouldn't be any conflict

That's good news. Thanks for your reply.

You are welcome

Have you ever met a case where two users did it exactly at the same time?
