Rename JSON Key

Rename the top-level field key to newkey in a JSON object. For example, {"key":"somevalue"} becomes {"newkey":"somevalue"}.

Use

In Open Flow, run with Record containing a JSON object. The Record output contains the transformed object. In n8n, edit Set to supply the fields, then run manually; Rename Keys returns the transformed item. The source example uses key with the value somevalue. No account or external service is required.

For reuse, provide one object to the Open Flow Start input. In n8n, connect your actual upstream items to Rename Keys in place of the Set demonstration. That node processes each incoming item separately; an empty item list produces no items. The template does not fetch, store or send the object.

At the rename step, the value, including null, an array or a nested object, is kept without conversion. Other fields remain. When key is absent, the object is unchanged. When newkey already exists, the source value replaces it. This template performs one fixed top-level rename; it does not recursively rename matching nested fields.

Changes to the source

• Accept a JSON object through Open Flow’s Start input in place of the editable n8n Set example.
• Keep the source rename, overwrite and missing-field behavior. The n8n Set and Rename Keys nodes retain their native versions and configuration.

Adapted from Rename Keys workflow in Zie619/n8n-workflows. The source export does not identify a separate template author or license.

The collection’s MIT notice is pinned at a later revision. This is the collection notice at that revision; it does not establish a separate original template author’s license. Our changes are listed above; see repository licensing.
