Extend an existing synthetic dataset by adding more rows or new columns while preserving FK integrity, ID continuity, and column distributions. It enables growing datasets without regenerating from scratch, while keeping the statistical properties and relationships intact across related tables.
Use synthdata-extend to add 500 rows to the orders table while preserving ID sequencing and FK relationships.

To extend a synthetic dataset while preserving FK integrity, append new rows that follow original column distributions and maintain ID sequencing, ensuring relationships across related tables remain intact without regenerating from scratch.
Yes, you can add new columns to CSV files while maintaining existing IDs and FK links. The skill uses companion schemas and basic type inference to ensure seamless integration of new attributes into your current dataset.
The best way to grow synthetic data across xlsx, csv, and json formats is to use deterministic augmentation that preserves column distributions and utilizes companion schemas to guide data generation for seamless integration.
Yes, extending a dataset with pandas and faker supports deterministic augmentation. The skill preserves column statistics and uses companion schemas to guide generation, ensuring statistically consistent data expansion.
You should not use synthetic data extension when you need to fundamentally alter original column distributions or schema structures. It is designed for appending rows or columns while preserving existing statistical properties, not for complete schema overhauls.
