How to handle delimiter(,) in csv

Question

Hi I need to transfer data(product details) from one online store to another. So I have exported data from source store in .CSV format. Now I want to create target store compatible .CSV to import to the target store. There are field like: "ProductCode,ProductName,ProductDescription" and so on. So in ProductDescription column if there is comma(,) present in ProductDescription so it goes to the next column from the comma(,). So please tell me that how can I bind whole description as one record for that particular product??
