What data type are you entering as the first argument to the kmeans command? According to the documentation, it has to be an n-by-p data matrix, but it looks like you have input a dataset instead.

I hope you are not offended by this statement, but it seems that you are new to MATLAB and new to clustering techniques, so it is difficult to try to explain both to you at the same time.
Regarding clustering:
Strictly speaking, K-means will not work on categorical data (to my knowledge), because it relies on a numerical distance function. There are related techniques like K-median and K-mode, but I don't know if MATLAB will help you with that.
Regarding getting a matrix from your Excel data:
I recommend that you open a new question about that. Post a small sample of your Excel file, and ask how to get the data into a matrix. Without seeing the data, it is almost impossible to suggest a specific technique.
