Overview
Extract Data Item is a specialized child node designed for use inside a Loop List. It extracts specified fields from the currently focused single list item and compiles these fields into structured data.
Use Cases
Extracting "Name, Price, Image, Rating" fields for each product in a product list.
Extracting "Title, Summary, Date, Likes" information in a post list.
Extracting "Job Title, Company, Location, Salary Range" in a job list.
Core Capabilities
Batch extracts multiple fields from the current list item.
Supports filling unified placeholder values (e.g., None) for missing fields.
Supports filtering criteria configuration to keep only data meeting specific conditions (e.g., posted within the last N days).
Configuration Steps
Add an Extract Data Item node inside a Loop List.
Configure Data Fields prompts to clearly describe the fields to extract, for example:
"Extract from current job item: Job Title, Company Name, Post Date, Salary Range. If missing, fill N/A."
(Optional) Configure Filtering Criteria, for example:
"Only keep jobs posted within the last 3 days."
Upon execution, Loop List runs Extract Data Item for each list item and aggregates the data into a table/dataset.
Recommendations
It is best to configure only one Extract Data Item node per Loop List to maintain a clear structure.
Clearer field descriptions lead to more stable extraction results; state field names and meanings clearly.
If the page structure is complex, consider splitting into multiple Loop List + Extract Data Item sets to extract by region.
