Datasets containing numerical and categorical data

Hello all, I have a dataset containing both numerical and categorical data. I want to use classification algorithms. Should I change all categorical values into numerical ones? I tried the dataset with the Classifier Learner, it's working but I can't be sure. Some of the classifiers are not selectable, is it because of the categorical data? Thanks for the help.

I think the information present under "Categorical Predictor Support" in the documentation page Choose Classifier Options, might help you.
