Run-clang-tidy script changes

I am modifying the run-clang-tidy script in order to NOT run clang-tidy checks on the specified files, my plan is to use a json / csv file which would have all the files that the clang-tidy should not run on. Should I continue with this approach or is there any better way to achieve this? If I continue on this path, which is better, csv or json in terms of ease of use for users? Regards, Suyash Dongre
