The present invention extends to methods, systems, and computer program products for exploring and selecting data cleansing service providers. Embodiments of the invention permit a user to explore different data cleansing service providers and compare quality results from the different data cleansing service providers. Sample data is mapped to a specified data domain. A list of service providers, for cleansing data for the selected data domain, is provided to a user. The user selects a subset of service providers. The sample data is submitted to the subset of service providers, which return results including allegedly cleansed data. The results are profiled and a comparison of the subset of service providers is presented to the user. The user selects a service provider to use when cleansing further data.
