COUNTIFS with Multiple Text Criteria in Same Criteria Range

As per title,

looking for a shortcut or alternative to type;

=SUM(COUNTIF(H2:H200{"A","B","C","D","E"}))

where A,B,C,D,E.....Z are several long text statements that I have listed, it would take a great deal of time to copy and paste then add quote marks and commas...

Thanks in advance

Thanks for the welcome and the swift reply Richard,

without being too specific, the end result of the project would be users picking any single value from text values A-Z and recording it in a single column. My aim is to produce a counter that counts the result of a group of those values, for example counting together all of those who chose A-G and K-N. The amount of people who chose D in the case of this project is not important enough to be counted seperately and summed on the main sheet. Your method is indeed valid and I am grateful,If it comes to it I will use it just on another sheet, however I am looking for something more streamlined, if it means I have to copy and paste the text one by one I may have to.

Someone suggested to me that the list of values can be converted to CSV in such a way that they gain the necessary commas and quote marks. Is this true?

Thanks in advance

Thanks so much Richard, your last post is exactly what I'm looking for. Much appreciated.
