Building an Automated Event Scraper with N8N: A Step-by-Step Guide

Creating an automated workflow to scrape event data can save countless hours of manual work while keeping you updated on local happenings. Using N8N, a powerful workflow automation tool, you can build a system that automatically extracts event information from websites and populates a Google spreadsheet with relevant data.

Understanding the Workflow

This N8N workflow is designed to scrape event data from specified websites and maintain an up-to-date Google spreadsheet of future events. Unlike more complex implementations, this workflow doesn’t require webhooks—it can be triggered manually or scheduled to run automatically.

Setting Up the Workflow

To create this workflow, start by clicking the plus button in N8N and selecting “Create Workflow.” You can then rename it according to your preference. The next step is creating a trigger, which you can do by clicking the plus button and selecting “Trigger.”

Configuring the Trigger

For this workflow, a schedule trigger works well. While it’s set up to trigger manually in this example, you can easily configure it to run automatically at midnight or any other preferred time to keep your data fresh.

Reading Source Data

The second step involves reading data from a Google Sheet that contains information about the websites you want to monitor. You’ll need to:

1. Set up Google Sheets credentials in N8N
2. Select the document containing your source URLs
3. Choose the appropriate sheet within that document

The source spreadsheet should contain columns for source ID, URL, active status, event type, and selection locators that help extract the specific data you need from each website.

Processing Each Source

Once the source data is retrieved, the workflow uses a for-loop to process each website entry. For each source, it:

1. Fetches the HTML content using the URL from the spreadsheet
2. Parses the data according to specified selection criteria
3. Transforms the extracted items into a structured format

Updating the Target Spreadsheet

After processing the data, the workflow updates a target Google spreadsheet (“future events”) with the newly extracted event information. The system is designed to:

1. Map columns automatically to match the event data structure
2. Filter to include only events happening from the current date forward
3. Remove past events that are no longer relevant

Customizing for Your Needs

This workflow provides a baseline that you can modify for your specific use case. Whether you’re tracking events in your local area, monitoring industry conferences, or keeping tabs on any other time-sensitive information, the structure can be adapted to suit your requirements.

Benefits of Automated Event Scraping

Implementing this type of workflow offers several advantages:

• Saves time by eliminating manual data collection
• Ensures you never miss relevant events
• Maintains an always up-to-date database of future events
• Can be extended to populate calendars or other applications

With a bit of knowledge about objects and arrays, plus the intuitive interface of N8N, you can create powerful automation tools that transform how you gather and manage information.
