Data Randomizer

$24.99

Sometimes you have a database full of data, but you do not want to use that exact data.  This may be due to personal data like addresses or phone numbers, or it may just be to avoid sending notifications to real users during testing.  The data randomizer is a way to move data that is real to a test or development table or to modify real data to make it safe for other uses.  It replaces real data with data that looks real but is not.
