Computer-implemented systems and methods are disclosed for providing proactive validations of transformation scripts. In one implementation, a method is provided that includes associating, with at least one processor, the transformation script with ontology parameters. The method also includes initiating a debugging operation of the transformation script having at least one condition and importing, from a data source, at least one data item for transformation. The method further includes determining, as part of the debugging operation, whether the at least one condition that uses the at least one data item is valid based on the ontology parameters and notifying a user, on a display device, of a result associated with the determination.
