I have a data set which will contain a list of email addresses and if they have passed a course. There will be multiple unique email addresses with a true or false cell related to each email. i am wanting to produce a list of the unique email addresses and the count of how many times the related cell contains 'True'.
I have had numerous tries with COUNTIF formulas and INDEX formulas but have not been successful. Any help will be much appreciated. I have attached an example of the raw data and what i would like the data to look like afterwards.
Thanks in advance.
