Comma Separated Values. Think excel, but instead of cells each column is separated by a comma and rows are separated by a new line (enter).
So the request is to create a list of key words and have them bulk-graded versus having to enter one keyword at a time. I'm assuming the OP wants the list returned as a CSV with the keyword, and its search volume, competition, and optimization scores. I assume OP also wants the total weighted score and if a Pro or higher subscriber, the view count of the bottom video in the top-ranking search results.
I can see how this would be useful. I wonder if it would create problems at the API-level with the rate of queries. I think the other risk is that you exhaust all of your keyword searches for the day before you find the best keyword.
