Synthetic demo data · repeated order IDs keep the first normalized row; no ambiguous values are guessed.
DEMO 02 · BUG FIX
Reproduce. Fix. Test.
A small percentage calculation bug, a focused correction, and regression tests for the expected result.
Self-created synthetic example · not client work
DEMO 03 · N8N
A small flow, shown plainly.
Manual TriggerMap Sample Fields
A harmless manual-trigger export maps two fixed sample fields. It has no credentials, makes no network calls, and is inactive.
