Fields fields	list of text	Selected fields: paths that together identify an item.

Set

Sets, renames or keeps fields of each item.

Inputs: main · Outputs: main

Parameter	Type	Description
Fields fields	key/value pairs	Field path (e.g. address.city) → value or expression.
Rename rename	key/value pairs	Old field path → new field path (applied before setting fields).
Keep only set fields keepOnlySet	true/false	Default: false.

Sort
