I get an error while importing arff data set into Weka ARFF viewer as: Illegal Pattern

And when i try to import the csv file into Weka Explorer, all the atrributes seems as one attribute: all_is_one_attribute

I read all the questions about these, also tried the suggested solutions but i didnt solve the import problem yet.

Could you upload a sample of your data? I am guessing your ARFF is not in the correct format. You can view the actual file in a text editor and it may give you some clues. cs.waikato.ac.nz/ml/weka/arff.html – Walter

From the image it seems that you use ; as a delimiter. Try to replace it with ,
