EXTRACT THE VALUE OF A RESPONSE NAME FROM A KEYVALUE¶
Extracts one or more named entries from a KeyValue collection and returns them as a new KeyValue. Use this worker when you need to filter a KeyValue down to a specific subset of keys by name (case-sensitive).
When to use¶
Classification: process.
Tagged: extract, filter, key-value, keyvalue, lookup, multiple, transformations.
Inputs¶
| Label | ID | Type | Default | Required | Description |
