Loop over items — beginner example
This workflow introduces beginners to one of the most fundamental concepts in n8n: looping over items. Using a simple use case—generating LinkedIn captions for content ideas—it demonstrates how to split a dataset into individual items, process them with AI, and collect the output for review or export. --- ✅ Key Features 🧪 Create Dummy Data: Simulate a small dataset of content ideas. 🔁 Loop Over Items: Process each row independently using the SplitInBatches node. 🧠 AI Caption Creation: Automatically generate LinkedIn captions using OpenAI. 🧰 Tool Integration: Enhance AI output with creativity-injection tools. 🧾 Final Output Set: Collect the original idea and generated caption. --- 🧰 What You’ll Need ✅ An OpenAI API key ✅ The LangChain nodes enabled in your n8n instance ✅ Basic knowledge of how to trigger and run workflows in n8n --- 🔧 Step-by-Step Setup 1️⃣ Run Workflow Node: Manual Trigger (Run Workflow) Purpose: Manually start the workflow for testing or learning. --- 2️⃣ Create Random Data Node: Create Random Data (Code) What it does: Simulates incoming data with multiple content ideas. Code: js return [ { json: { row_number: 2, id: 1, Date: '2025-07-30', idea: 'n8n rises to the top', caption: '', complete: '' } }, { json: { row_number: 3, id: 2, Date: '2025-07-31', idea: 'n8n nodes', caption: '', complete: '' } }, { json: { row_number: 4, id: 3, Date: '2025-08-01', idea: 'n8n use cases for marketing', caption: '', complete: '' } } ]; --- 3️⃣ Loop Over Items Node: Loop Over Items (SplitInBatches) Purpose: Sends one record at a time to the next node. Why It Matters: Loops in n8n are created using this node when you want to iterate over multiple items. --- 4️⃣ Create Captions with AI Node: Create Captions (LangChain Agent) Prompt: text idea: {{ $json.idea }} System Message: text You are a helpful assistant creating captions for a LinkedIn post. Please create a LinkedIn caption for the idea. Model: GPT-4o Mini or GPT-3.5 Credentials Required: OpenAI Credential Go to: OpenAI API Keys Create a key and add it in n8n under credentials as “OpenAi account” --- 5️⃣ Inject Creativity (Optional) Node: Tool: Inject Creativity (LangChain Tool) Purpose: Demonstrates optional LangChain tools that can enhance or manipulate input/output. Why It’s Cool: A great way to show chaining tools to AI agents. --- 6️⃣ Output Table Node: Output Table (Set) Purpose: Combines original ideas and generated captions into final structure. Fields: idea: ={{ $('Create Random Data').item.json.idea }} output: ={{ $json.output }} --- 💡 Educational Value This workflow demonstrates: Creating dynamic inputs with the Code node Using SplitInBatches to simulate looping Sending dynamic prompts to an AI model Using Set to structure the output data Beginners will understand how item-level processing works in n8n and how powerful looping combined with AI can be. --- 📬 Need Help or Want to Customize This?

By Robert BreenExtract pay slip data with Line Chatbot and Gemini to Google Sheets
Workflow Overview: Extract text from image using AI is worth because you need no code. It incorporates Google Gemini 2.0 Flash model for important text extraction from image. If you code without AI, you have to use multiple condition and may cause a lot of bug but with Google Gemini, you don't need any coding and if the Pay Slip is different, Gemini will extract it automatically. Workflow description: User uses Line Messaging API to send Pay Slip image or message to the chatbot, create Line Business ID from here: Line Business Classify the message which is image or text If the message is Pay Slip image, it will process using Gemini 2.0 Flash EXP and extract important information and response in JSON format without coding by using the following prompt: Analyze image and then return in JSON Response that has the only following value: Status, From, To, Date, Amount To get Google AI Studio API Key, you can find from the following link: Google AI Studio API Key Create Google Sheets which include the fileds (Status, From, To, Date, Amount) that we have created related to the AI prompt Google Sheets as the following example: If the message is text, it will process using Gemini 2.0 Flash EXP model as the AI Assistant else if the message is image, it will extract the important fields then reply to the User and insert into Google Sheets Key Features: Extract text from image with No Code Without N8N, we have to write code to extract text from image, but with N8N and Google Gemini 2.0 Flash EXP together, we don't need to code and it will process all slip vendors or other document vendors. Multipurpose Chatbot this chatbot accept both text and image so we don't have to create many chatbot accounts Reduce human error this workflow let any officer to verify document status when the job ends Note: You can change the information by changing your prompt and also Google Sheets Column names relatively.
By Sirisak ChantanateAutomated TikTok video downloader bot (no watermark) using n8n and Telegram
Description This workflow is an n8n-based automation that allows users to download TikTok/Reels videos without watermarks simply by sending the video link through a Telegram Bot. It uses a Telegram Trigger to receive the link from the user, then makes an HTTP request to a third-party API (tiktokio.com) to process and retrieve the download link. The workflow filters the results to find the Download without watermark link, downloads the video in MP4 format, and sends it back to the user directly in their Telegram chat. Key features: Supports the best available video quality (bestvideo+bestaudio). Automatically removes watermarks. Instant response directly in Telegram chat. Fully automated — no manual downloads required. How It Works Telegram Trigger The user sends a TikTok or Reels link to the Telegram bot. The workflow captures and stores the link for processing. HTTP Request – MediaDL API The link is sent via POST method to https://mediadl.app/api/download. The API processes the link and returns video file data. Wait Delay The workflow waits a few seconds to ensure the API response is fully ready. Edit Fields Extracts the video file URL from the API response. Additional Wait Delay Adds a short pause to avoid connection errors during the download process. HTTP Request – Proxy Download Downloads the MP4 video file directly from the filtered URL. Send Video via Telegram The downloaded video is sent back to the user in their Telegram chat. How to Set Up Create & Configure a Telegram Bot Open Telegram and search for BotFather. Send /newbot → choose a name & username for your bot. Copy the Bot Token provided — you’ll need it in n8n. Prepare Your n8n Environment Log in to your n8n instance (self-hosted or n8n Cloud). Go to Credentials → create new Telegram API credentials using your Bot Token. Import the Workflow In n8n, click Import and select the PROJECTDOWNLOADTIKTOK_REELS.json file. Configure the Telegram Nodes In the Telegram Trigger and Send Video nodes, connect your Telegram API credentials. Configure the HTTP Request Nodes Ensure the Download2 and HTTP Request nodes have the correct URL and headers (pre-configured for mediadl.app). Make sure the responseFormat is set to file in the final download node. Activate the Workflow Toggle Activate in the top right corner of n8n. Test by sending a TikTok or Reels link to your bot — you should receive the no-watermark video in return.
By GarriCrypto RSI alert system with EODHD, Telegram and TradingView charts
How it works Runs on a schedule and iterates a watchlist of symbols (e.g., BTC/ETH/SOL). For each symbol, request intraday 1h OHLCV from EODHD. A Code node computes Wilder’s RSI(14) and detects 30/70 crossings. When a signal appears, the bot sends a Telegram alert (HTML message) with price, RSI (prev → now), timestamp, and a “View chart” button that opens the pair on TradingView (BINANCE/USD). Set up steps (≈10–15 min) Prereqs: n8n (cloud or self-hosted), EODHD API key, Telegram bot + your chat_id. Env vars: set EODHDTOKEN and TELEGRAMCHAT_ID on your n8n instance. Credentials: add your Telegram credential (bot token). Import the workflow JSON. Edit Fields node: adjust the symbol array to your watchlist. Schedule Trigger: choose how often to run (e.g., every 5–10 min). Test: temporarily flip the Code node’s FORCE_ALERT flag to true to verify Telegram delivery, then set it back to false. EODHD API Access the EODHD API with a 10% discount
