Researchers have developed ORiGAMi, a novel autoregressive transformer architecture designed to synthesize sparse and semi-structured JSON data without the need for flattening. This approach preserves the inherent structure of JSON records, unlike traditional methods that convert them into wide, sparse tables. ORiGAMi serializes JSON into key, value, and structural tokens, encoding their positions within the document tree and enforcing grammar and schema constraints. Evaluations across six datasets demonstrated that ORiGAMi outperformed existing baselines in 17 out of 18 comparisons for fidelity, detection, and utility metrics, while also maintaining high privacy scores.
