Decision tree/ What format of excel can be used in RapidMiner?

hello @ranya2670 - welcome to the community.  We'd be happy to help but could you please post your "Soccer" data set and your XML process here in the thread so we can see what is going on?  Screenshots do not help very much.  Instructions are on the right under "Read Before Posting" when you reply.

Good morning Selina,

This should do the trick.

Hi 

I am still not able to get a decision tree on my computer with the process you attached. It says 'file not found'. What is the problem?

I just cleansed my dataset so I will upload the new one and the code again. Can you then tell me how I can run the process on my computer without error?

I'm not sure what error you are talking about, but it works fine for me.

hello.  Yes I slightly changed your process so that it would read from the csv instead of from your repository.  So that error message is because the path to the file on my computer is obviously different than it would be on your computer.  You just need to change the filepath in Read CSV.
