Comparing 2 tables best practice
Hi guys
I have a 2 tables to compare (excel source)
I have an idea what to do with itπ, but I thought maybe you have better/faster way of comparing 2 tables:
1. 2 tables - there is common ID column ( may happen that one table has more rows tho)
Is lookup option would be better or merge?
2. column names are different ( I have a key in excel ).
Should I renemed them in bulk or there is way to create 3rd table and use it as a reference.
3. Values in 1 table can be YES NO, in table 2 TRUE FALSE
You recommnend to rename them in power query beforhand or perhaps is more clever way to do it.
Thanks in advance for any ideas
