The present invention is directed to a system that enables an associate (a data specialist, an agent, an analyst, or the like) to efficiently and accurately validate customer data (e.g., determine if customer data between two or more sets of customer data is consistently accurate). In this way, the system of the present invention is configured to enable the associate to run automated tests (e.g., trials) where first customer data from a first customer data set is compared to second customer data from a second customer data set to determine one or more differences between the first and second customer data. After the comparison is complete, the system of the present invention is configured to generate a file (e.g., a third customer data set) that identifies the determined differences, and provides a standardized report summarizing the determined differences.
