1. A system for creating and modifying test data files comprising: (a) a monitor; (b) a memory; (c) a parse map editor; and (b) a test data file editor; wherein parse maps are created and edited in the parse map editor; wherein the system parses incoming test data files based on the parse maps that are created in the parse map editor; wherein each incoming test data file is matched to a parse map; wherein the parsed test data files are sent to the test data file editor; wherein the test data file editor allows a user to view and edit the parsed test data wherein the test data file editor automatically creates and modifies test data files; wherein the test data files are used to test a computer program having application logic, wherein the application logic comprises a set of conditions, wherein the test data files encompass all of the conditions within the application logic of tile computer program; and wherein the system identifies personal data elements in an incoming production data file, and a replacement or scrambling routine adjusts the data in each one of the personal data elements to convert the production data file to a test data file that can be used for testing purposes without any actual personal data.
