My postal code file has non-alpha numeric characters. Is that a problem?

Before uploading a postal code file, clean it in Excel using the Find and Select feature to remove non-alphanumeric characters like spaces, – or /.  Keep in mind there is no letter O in postal codes. You may wish to consider replacing the letter O with a zero before uploading your Files. While intelligentVIEW will automatically remove some of these characters, loading a clean file will ensure the most accurate analysis.
