Hello Experts!
Please pour your suggestions on how to create a power automate flow for below requirement i tried with couple of ways like compare and highlight the differences and ended up with issues.
Requirement:
Every month end we will get an excel sheet which contains list of users from a project ,every month new users will be onboarded and off boarded. I need to create a flow which compare the current month data(July2021.xlsx) and previous month data(June2021.xlsx)
and find the differences of two excel sheets and find how many new users has been onboarded and how many existing users are offboarded and need to show the differences in new excel sheet (output_diff.xlsx)
Expected output as below,
