How to read a number, then convert to corresponding string and stats table?

[bryceweb22]

I am trying to extract a module/level ID from my logs and have splunk take that ID and match it to the corresponding name from a csv file and put that into a stats table, please help.

Thanks!

YourSearch | rex field=_raw max_match=0 "level ID":\"(?< ID>\d+)\""
| lookup file.csv level ID as ID OUTPUT corresponding_name
| table corresponding_name count

Save your .csv to lookup folder

file.csv

ID corresponding_name
1 A
2 B

This should work.
