The present disclosure involves systems, software, and computer-implemented methods for generating data regulation-compliant data from application interface data. One example method includes receiving a request for creation of document data. The request includes personal data of a user. Document data, including at least some of the personal data, is created based on the request. The document data is encoded into an encoded document that does not include any personal data of the user and includes structural information that describes the structure of the document data. A request to use the encoded document is received and the encoded document is decoded. A synthetic document is generated using the structural information included in the encoded document. Generation of the synthetic document includes insertion of synthetic user data into the synthetic document at positions in the synthetic document that correspond to positions of personal data within the document data.
