Analyze tradingview.com charts with Chrome extension, n8n and OpenAI
This flow is supported by a Chrome plugin created with Cursor AI.
The idea was to create a Chrome plugin and a backend service in N8N to do chart analytics with OpenAI. It's a good sample on how to submit a screenshot from the browser to N8N.
Who is it for? N8N developers who want to learn about using a Chrome plugin, an N8N webhook and OpenAI.
What opportunity does it present? This sample opens up a whole range of N8N connected Chrome extensions that can analyze screenshots by using OpenAI.
What this workflow does? The workflow contains:
- a webhook trigger
- an OpenAI node with GPT-4O-MINI and Analyze Image selected
- a response node to send back the Text that was created after analysing the screenshot.
All this is needed to talk to the Chrome extension which is created with Cursor AI.
The idea is to visit the tradingview.com crypto charts, click the Chrome plugin and get back analytics about the shown chart in understandable language. This is driven by the N8N flow.
With the new image analytics capabilities of OpenAI this opens up a world of opportunities.
Requirements/setup
How to customize it to your needs? Both the Chrome extension and N8N flow can be adapted to use on other websites. You can consider:
- analyzing a financial screen and ask questions about the data shown
- analyzing other charts
- extending the N8N workflow with other AI nodes
With AI and image analytics the sky is the limit and in some cases it saves you from creating complex API integrations.
n8n Workflow: Analyze TradingView Charts with OpenAI
This n8n workflow provides a powerful way to integrate chart analysis from TradingView.com (presumably via a Chrome Extension) with OpenAI's advanced AI capabilities. It acts as a bridge, allowing you to send data from your browsing session to an AI for analysis and receive an immediate response.
What it does
This workflow automates the following steps:
- Receives Data via Webhook: It listens for incoming HTTP POST requests, likely from a Chrome extension or another application that extracts data from TradingView.com charts.
- Sends Data to OpenAI: The received data is then forwarded to the OpenAI node, where it can be processed by an AI model (e.g., for sentiment analysis, pattern recognition, or generating insights based on the chart data).
- Responds to Webhook: The AI's response from OpenAI is then sent back as the HTTP response to the original webhook caller, providing real-time feedback or analysis.
Prerequisites/Requirements
To use this workflow, you will need:
- n8n instance: A running n8n instance (self-hosted or cloud).
- OpenAI API Key: An API key for OpenAI to access their models. This will need to be configured as a credential within n8n for the OpenAI node.
- Data Source (e.g., Chrome Extension): An external mechanism (like a custom Chrome extension) capable of extracting chart data from TradingView.com and sending it as an HTTP POST request to the n8n webhook URL.
Setup/Usage
- Import the Workflow:
- Download the provided JSON file.
- In your n8n instance, click "Workflows" in the left sidebar.
- Click "New Workflow" and then "Import from JSON".
- Paste the JSON content or upload the file.
- Configure OpenAI Credentials:
- Locate the "OpenAI" node in the workflow.
- Click on the node and then select "Credentials".
- Add or select your OpenAI API Key credential. If you don't have one, create a new credential of type "OpenAI API" and enter your API key.
- Activate the Webhook:
- The "Webhook" node will generate a unique URL when the workflow is activated. Copy this URL.
- Configure Your Data Source:
- Set up your Chrome extension (or other data source) to send a POST request with the TradingView chart data to the copied Webhook URL. The data should be formatted in a way that the OpenAI node can process (e.g., JSON with relevant chart parameters, indicators, or a description).
- Activate the Workflow:
- Toggle the workflow to "Active" in the top right corner of the n8n editor.
Once activated, any data sent to the webhook URL will trigger the workflow, send the data to OpenAI for analysis, and return the AI's response to the caller.

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?

By Shadrack🎓 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 – sender’s email address To – recipient’s email address Subject – email subject line Summary – 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 ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ 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?
