How it works

This workflow automates the extraction of real estate listings from Idealista by performing two main phases: listing URL discovery and detailed data extraction.

1. Trigger and Pagination Setup A Manual Trigger starts the workflow. A Set node defines the base search URL and the maximum number of pages to scrape. A Code node then generates the paginated URLs (e.g., .../lista-1.htm, .../lista-2.htm).

2. Extract Listing URLs from Search Pages The generated URLs are split into batches using a Split In Batches node. For each search page, a ScrapegraphAI node extracts all individual property URLs that match the pattern https://www.idealista.it/immobile/xxxx. The results are then aggregated and unified using an Aggregate and a Code node to remove duplicates and flatten the list.

3. Process Each Property URL The unified list of property URLs is split again into batches. For each property URL, a second ScrapegraphAI node extracts detailed information following a strict JSON schema (including title, description, price, area, bedrooms, bathrooms, floor, rooms, balcony, terrace, cellar, heating, air conditioning, and image URLs).

4. Store Data in Google Sheets The extracted data is finally written to a Google Sheet using the Google Sheets node configured with appendOrUpdate mode, which avoids duplicates by matching the URL column.

Set up steps

1. Import and Configure Credentials Import the workflow into n8n. Add the following credentials:

• ScrapegraphAI API (used by both ScrapegraphAI nodes).
• Google Sheets OAuth2 (used for writing data).

1. Prepare the Google Sheet Clone this template sheet or create your own. Update the Google Sheets node with your Document ID and Sheet Name.

2. Configure the Search Parameters In the Set params node, modify the url variable to target your desired search (location, filters, etc.) and set max_pages to control how many search result pages to scrape.

3. Adjust Extraction Logic (if needed)

• Verify that the Scrape listings node’s prompt correctly matches the listing URL structure of your target site.
• Update the Extract data node’s outputSchema (JSON schema) to match the fields you want to extract.

1. Enable and Execute Activate the workflow. Click the Execute Workflow button to start scraping. The results will automatically populate the configured Google Sheet, appending new listing data without creating duplicates.
