You say you want to remove duplicates but when you run Remove Duplicates you do not get what you want! you have used advances filtering and you do not get the result you need!, you say there are approximately 350 values in column A but when you get the result you want there should only be 10-12 values in column B, must be honest and say I am struggling to understand your requirements
And if it still doesn't give you the results you intend to then check if the data is really the same e.g. sometimes some invisible characters like white space are there which appear to be the same but aren't the same.
"Chandorg"
"Chandorg "
Place them in Excel without quotes and you won't notice a difference.
Advanced filtering is returning only one value(the first value from column A) and I have this message:"The extract range has a missing or illegal field name".
In column A are only numbers so no special characters.
One more thing: all cells in col. A have associated a formula (I am thinking perhaps this is why the filtering is not working).
Is there a formula that can help me avoid their filtering?
