|---|---|---|
| 2 | 1 | {"device":"ios","items":["SKU-A","SKU-B"]} |
| 4 | 2 | {"device":"web","items":["SKU-C"]} |
2 rows — all rows shown.

|---|---|---|---|
| 2 | 1 | ios | SKU-A |
| 2 | 1 | ios | SKU-B |
| 4 | 2 | web | SKU-C |
3 rows — all rows shown.

Expected skills
JSON extraction, array expansion, and item-grain output.
