This workflow allows users to generate beautifully stylized 3D-rendered food emoji icons based on a simple text prompt. It combines user input, structured visual design generation, and image rendering using OpenAI’s GPT models.

✨ What It Does

  1. Collects user input via a form: e.g. "green apple"
  2. Generates a structured JSON specification describing the emoji’s form, lighting, texture, and color scheme
  3. Uses AI to render an image based on that spec—styled like a high-quality emoji icon with a transparent background

🧠 Use Case

This template is ideal for:

  • Designers or creators needing icon ideas or drafts for food items
  • Developers building emoji packs or digital stickers
  • Inspiration for AI-assisted product illustration or branding

💡 Why It's Useful

Instead of prompting a model directly with vague terms, this flow creates a structured visual spec tailored to food items. The final emoji-style icon is polished, modern, and downloadable.

✅ Requirements

To get started with this workflow, follow these steps:

  1. 🔑 Configure Credentials: Set up your API credentials for OpenAI and Google Drive
  2. 💳 Add OpoenAI Credit: Make sure to add credit to your OpenAI account, verify your organization (required for generating images)
  3. 📊 Connect Google Drive: Authenticate your Google Drive account
  4. ⚙️ (Optional) Customize Prompts: Adjust the prompts within the workflow to better suit your specific needs

Note: Each image generation will cost you about $0.17

n8n Workflow: Create Food Emoji Icons with OpenAI GPT Image Generation

This n8n workflow demonstrates how to leverage OpenAI's image generation capabilities to create custom food emoji icons. It provides a simple form interface to trigger the image generation process, allowing users to easily request new food-related emojis.

What it does

This workflow automates the following steps:

  1. Triggers on Form Submission: It starts when a user submits data through an n8n form.
  2. Edits Fields (Set Node): This node is present but currently configured without specific field modifications. It could be used to transform or add data before sending it to OpenAI.
  3. Generates Images with OpenAI: It sends a prompt to OpenAI to generate an image based on the input received from the form.
  4. Google Drive (Placeholder): This node is included in the workflow but not connected. It suggests a potential future enhancement to store the generated images in Google Drive.
  5. Sticky Note (Documentation): A sticky note is included for documentation purposes, providing context or instructions within the workflow itself.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance (cloud or self-hosted).
  • OpenAI API Key: An OpenAI account and an API key with access to image generation models (e.g., DALL-E). This will need to be configured as an n8n credential.

Setup/Usage

  1. Import the workflow: Download the JSON provided and import it into your n8n instance.
  2. Configure OpenAI Credentials:
    • Click on the "OpenAI" node.
    • Under "Credentials", click "Create New".
    • Select "OpenAI API" and enter your OpenAI API Key.
    • Save the credential.
  3. Activate the Workflow: Toggle the workflow to "Active" in the top right corner of the n8n editor.
  4. Access the Form:
    • Click on the "On form submission" (n8n Form Trigger) node.
    • Copy the "Webhook URL" provided.
    • Open this URL in your browser to access the form.
  5. Submit a Request: Fill out the form with your desired food emoji description and submit it. The workflow will then execute, generating an image via OpenAI.

(Optional) To store the generated images in Google Drive, you would need to:

  1. Configure a Google Drive credential in n8n.
  2. Connect the "OpenAI" node's output to the "Google Drive" node.

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?

🎓 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?
