An apparatus includes a memory and a processor. The processor receives a request to validate target data against source data. The processor identifies a disagreement between an element of source data and a corresponding element of target data. The disagreement indicates that the ordered set of alphanumeric characters representing the source element is different from the ordered set of alphanumeric characters representing the target element. In response to identifying the disagreement, the processor determines that the source element does not match the target element, where the source element includes a first value stored according to a first format, and the target element includes a second value stored according to a second format. In response, the processor extracts an element of the source data corresponding to the source element, transforms this element from the first format to the second format, and loads it into the target data.
