automation to save files based on keywords

I separate photos by keywords and have about 300 keywords after a weekend photoshoot. Some keywords may have only one image associated with a keyword, whereas others will have multiple photos. I can see a list of all my keywords in the Library and how many photos are associated with each keyword. Now I want to save each keyword as a folder with the images associated. For example, if I have a keyword of "121x" with 18 photos, I want to save all 18 pictures as an export into a folder called 121x.

I would like to see an automated process that cycles to each keyword and exports it into a subfolder with the same keyword name.
