Replace all sheet values with their RANK

Attached is an excel file that contains all possible values in the first column (9238 of them) and a comma separated list of a subset of those values in the second column. I need to find a way to replace the smallest value with 1, the next smallest value with 2, ... , and the largest value with 9238 in every instance. In other words, I need their rank value. Is there a relatively easy way to do this? Thank you for any response.
