Changelog

Track all the features, improvements, and fixes in Synthetic Data Generator

v2.3.0

January 25, 2026

Minor Release

🔧

AI Generate Full Data – Schema-Aware

Generate Full Data in AI tab now uses the current schema and patterns. The n8n simple generator workflow was updated to read the request body correctly (supports both n8n body-at-root and body-in-.body). Frontend-v3 now sends sampleData when available so the generator can extract patterns when fieldPatterns are not set.
🔧

Schema Builder Preview Tabs (TABLE / RAW / SQL)

Fixed preview modal on the Schema Builder tab so TABLE, RAW, and SQL tabs switch correctly. The active class is now toggled on both tab buttons and the corresponding view divs so the correct content is shown.
✨

Simple Generator Workflow (n8n)

Updated workflow file simple-generator-user-updated.json supports body-at-root and optional fieldPatterns from the request. One workflow serves both Schema Builder (schema-only) and AI Mode (schema + sampleData/fieldPatterns).
