What Is the Set Node (Edit Fields) in n8n?
The Set node, renamed Edit Fields in newer n8n versions, creates, edits, renames, or removes fields on the data items flowing through your workflow. It is how you shape, clean, and standardize data between two nodes without writing code, using either a visual field mapper or raw JSON. Think of it as the node that decides exactly what data moves forward.
How to Use the Set Node in n8n
Add an Edit Fields (Set) node, then pick a mode. Manual Mapping lets you add each field name and value, dragging in values from earlier nodes as expressions. JSON mode lets you define the whole output object at once. Turn on "Keep Only Set" to drop every other field and pass a clean payload to the next node or API.
Common uses: rename keys to match an API, set default values, type-cast strings to numbers, or trim a large object down to only the fields the next step needs.
