Using M in Query Editor, I'm looking for a simple and efficient means by which to remove non-letters from a text column in a table. For example, if the first two rows within a column have values "this is not all_text!" and "1234Letters$" I'd like them to become "this is not all text" and "Letters". A few entries also have emojis that are pulled into the query, and I'd also like to scrub those out. Any suggestions are appreciated!
