Restore .dmp file into csv

We have asked our clients for certain data in a csv file format and we just got a .dmp file. I have been trying to open it using MySQL as if it were .dump but it doesn't work. I have seen other posts where they restore .dmp files with Oracle but I have 0 experience with Oracle (and very little with databases overall). Is there any alternative to get the contents of the .dmp file into a csv format?
