Extract Field
Pull a specific field or dot-notation path from upstream JSON data.
Overview
The Extract Field node reads structured JSON from an upstream node and extracts one field (or a path of nested fields) as its output. It has two input modes: a Dropdown that lists fields detected from the upstream schema, and a Custom path mode where you type a dot-notation path manually. The output can be a single text string, a list of items for fan-out, or a raw JSON value for chaining into another Extract Field or JSON Process node.
This node executes inline (no job created, no credits charged).
When to Use
- Pull
titleorurlout of a Google Search or RSS result set before feeding a List fan-out - Extract a nested property like
authorMeta.namefrom TikTok posts - Convert a JSON array from Web Scrape into a text list for Generate Text
- Chain two Extract Field nodes to drill into deeply nested JSON
Configuration
| Field | Type | Default | Description |
|---|---|---|---|
| Field | dropdown / text | "" |
The field or dot-path to extract. Empty = whole item (returns each array element as-is). Detected options appear when an upstream node is connected. |
| Mode | toggle (auto) | dropdown |
Auto-selected. Switches to Custom path… for arbitrary dot-notation entry. |
| Output Type | select | text |
How the result is emitted to downstream nodes (see below). |
Output Type options
| Value | Behaviour |
|---|---|
text |
Values are joined by newline into a single string. Works with any text-accepting node. |
list |
Each match is a separate list item — supports item:N, fan-out, and List-aware nodes. |
json |
Raw JSON value — use when feeding another Extract Field or a JSON-consuming node. |
Inputs & Outputs
Inputs: Any upstream node that emits JSON, a JSON string, or a list.
Outputs: text — the extracted value(s) in the selected format.

Common Use Cases
- Web Scrape → Extract Field (
title) → List → Generate Image (one per headline) - Web Scrape (RSS) → Extract Field (
url,list) → Selector → text-prompt chaining - JSON Process → Extract Field (nested path) → Generate Text
- TikTok scrape → Extract Field (
caption) → Generate Text for remixing captions
Tips
- Connect an upstream node first — the dropdown auto-populates with detected fields from the upstream schema, saving you from memorising key names.
- Leave Field blank and set Output Type to
listto emit each top-level item of an array individually — useful when the JSON is already a flat list of values like["a", "b", "c"]. - Use dot notation in custom mode for nested objects:
authorMeta.name,videoMeta.duration. - Chain two Extract Field nodes when the path has array segments in the middle (e.g., first extract
items, then extractitems[].titleby chaining a second node with fieldtitle).
