n8n Workflow: Create AI-Ready Vector Datasets from Web Content
This n8n workflow provides a foundational structure for processing web content to prepare it for AI applications, specifically focusing on creating vector datasets. It demonstrates how to initiate a process, make an HTTP request, and apply conditional logic based on the response.
What it does
This workflow outlines a process that can be extended to:
- Manually Trigger Execution: Starts the workflow on demand, allowing for manual initiation of the data processing.
- Make an HTTP Request: Sends a request to a specified URL. This is typically used to fetch web content, interact with an API, or initiate an external process.
- Apply Conditional Logic: Evaluates the outcome of the HTTP request. This allows for branching the workflow based on whether the request was successful or met specific criteria.
- Edit Fields (Set): If the HTTP request meets the defined condition, this node prepares or transforms the data for further processing, such as extracting relevant information or structuring it for vectorization.
- Execute Custom Code: If the HTTP request does not meet the defined condition, this node allows for running custom JavaScript code. This could be used for error handling, logging, or alternative data processing paths.
Prerequisites/Requirements
- n8n Instance: A running instance of n8n to import and execute the workflow.
- Target API/URL: An endpoint or web page that the HTTP Request node will interact with.
Setup/Usage
- Import the workflow: Copy the provided JSON and import it into your n8n instance.
- Configure the "HTTP Request" node:
- Set the
URLto the web content source or API endpoint you wish to interact with. - Configure any necessary
Headers,Query Parameters, orBodyfor your request.
- Set the
- Configure the "If" node:
- Define the
Conditionsto evaluate the response from the "HTTP Request" node. For example, you might check for a specific HTTP status code (e.g., 200 for success) or a particular value in the response body.
- Define the
- Configure the "Edit Fields (Set)" node (True branch):
- If the "If" node evaluates to
True, this node will execute. Configure it to extract, rename, or transform data from the HTTP response as needed for your AI-ready dataset.
- If the "If" node evaluates to
- Configure the "Code" node (False branch):
- If the "If" node evaluates to
False, this node will execute. Add custom JavaScript code here for error handling, logging, or alternative processing.
- If the "If" node evaluates to
- Extend the workflow: This workflow provides a starting point. You can connect additional nodes after the "Edit Fields (Set)" node to:
- Extract Text: Use a "Cheerio" or "HTML Extract" node to parse web content.
- Generate Embeddings: Integrate with an AI model (e.g., OpenAI, Cohere, local Ollama) to create vector embeddings from the extracted text.
- Store Vectors: Connect to a vector database (e.g., Qdrant, Pinecone, Weaviate) to store the generated vectors and associated metadata.
- Notifications: Send notifications (e.g., Slack, Email) about the processing status or errors.
- Execute the workflow: Click the "Execute Workflow" button on the "Manual Trigger" node to run the workflow.

Automate Dutch Public Procurement Data Collection with TenderNed
TenderNed Public Procurement What This Workflow Does This workflow automates the collection of public procurement data from TenderNed (the official Dutch tender platform). It: Fetches the latest tender publications from the TenderNed API Retrieves detailed information in both XML and JSON formats for each tender Parses and extracts key information like organization names, titles, descriptions, and reference numbers Filters results based on your custom criteria Stores the data in a database for easy querying and analysis Setup Instructions This template comes with sticky notes providing step-by-step instructions in Dutch and various query options you can customize. Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only. Step 8: Store Inserts the processed data into your database for storage and future analysis. Customization Tips Modify API Parameters In the "Tenderned Publicaties" node, you can adjust: offset: Starting position for pagination size: Number of results per request (max 100) Add query parameters for date ranges, status filters, etc. Add More Fields Extend the "Splits Alle Velden" node to extract additional fields from the XML/JSON data, such as: Contract value estimates Deadline dates CPV codes (procurement classification) Contact information Integrate Notifications Add a Slack, Email, or Discord node after the filter to get notified about new matching tenders. Incremental Updates Modify the workflow to only fetch new tenders by: Storing the last execution timestamp Adding date filters to the API query Only processing publications newer than the last run Troubleshooting No data returned? Verify your TenderNed API credentials are correct Check that you have setup youre filter proper Need help setting this up or interested in a complete tender analysis solution?

π How to transform unstructured email data into structured format with AI agent
This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From β senderβs email address To β recipientβs email address Subject β email subject line Summary β short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits β Full Automation: Eliminates manual reading and data entry from incoming emails. β Multi-Source Integration: Handles data from different email providers seamlessly. β AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. β Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. β Time Efficiency: Processes emails in real time, improving productivity and response speed. *β Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
