Example: AI-Powered Sentiment Analysis & Response Draft 💬

This n8n code snippet demonstrates how to take text input, send it to a hypothetical AI sentiment analysis service, and then based on the sentiment, generate a draft response. It leverages the HTTP Request node for AI API interaction and the Code node for conditional logic and data manipulation. This is akin to giving your workflow a basic emotional intelligence, enabling it to respond appropriately.

// This code runs in an n8n Code node.
// It assumes the previous node provided text input and
// that an HTTP Request node for sentiment analysis has already run,
// outputting a sentiment score.

// Access the data from the previous node (e.g., HTTP Request to an AI API)
// We're assuming the AI service returns a 'sentimentResult' key.
const sentimentAnalysisResult = items[0].json.sentimentResult;
// We also grab the original text to include in our response.
const originalInputText = items[0].json.inputText;

let responseDraft = '';
let sentimentCategory = 'neutral';

// Define thresholds for positive and negative sentiment.
// A higher value indicates more positive sentiment.
if (sentimentAnalysisResult > 0.7) { // If the score is above 0.7, it's strongly positive.
    sentimentCategory = 'positive';
    responseDraft = `Great to hear! We're thrilled you had a good experience with "${originalInputText}". How else can we help? We love making our users happy!`;
} else if (sentimentAnalysisResult < 0.3) { // If the score is below 0.3, it's negative.
    sentimentCategory = 'negative';
    responseDraft = `We're truly sorry to hear about your experience with "${originalInputText}". Please provide more details so we can assist you better and turn things around.`;
} else { // Otherwise, it's considered neutral.
    responseDraft = `Thanks for reaching out about "${originalInputText}". We'll get back to you shortly and appreciate your patience.`;
}

// Output the determined sentiment category and the generated response draft.
// This data can then be used by subsequent nodes, e.g., to send an email or update a CRM.
return [{
    json: {
        sentiment: sentimentCategory,
        responseDraft: responseDraft
    }
}];

This powerful Code node acts as the brain, interpreting the sentiment score (often a number between 0 and 1) and crafting a human-like response. It’s like having a digital assistant who not only understands emotions but can also initiate a suitable conversation. This capability highlights a significant area for the best use of n8n in 2025.

Example: Data Transformation for Consolidated Sales Report 📈

This JavaScript snippet for an n8n Code node illustrates how to take heterogeneous sales data from different sources (assuming they arrive as an array of objects). It then standardizes product categories, calculates total sales per item, and prepares it for a unified report. This is a common and highly effective pattern for the best use of n8n in data handling and ensuring data consistency across your organization.

// This code runs in an n8n Code node.
// It expects an array of sales items from previous nodes, possibly with varied structures
// (e.g., from different e-commerce platforms with slightly different field names).

const normalizedSales = [];

// Helper function to normalize product categories.
// This ensures that 'Electronics', 'electronics', 'Electronic Gadgets' all map to a single 'Electronics' category.
function normalizeCategory(category) {
    if (!category) return 'Uncategorized'; // Handle cases where category might be missing
    const lowerCaseCategory = category.toLowerCase();
    if (lowerCaseCategory.includes('electronics')) return 'Electronics';
    if (lowerCaseCategory.includes('clothing') || lowerCaseCategory.includes('apparel')) return 'Apparel';
    if (lowerCaseCategory.includes('book')) return 'Books';
    return 'Other'; // Default category if no specific match
}

// Iterate over each incoming item (which represents a sales record).
for (const item of items) {
    const sale = item.json; // Access the JSON data of the current item.

    // Extracting and standardizing fields.
    // We use '||' to provide fallbacks for different possible field names or default values.
    const productName = sale.productName || sale.itemTitle || 'Unknown Product';
    const quantity = parseInt(sale.quantity || 0, 10); // Ensure quantity is an integer.
    const price = parseFloat(sale.unitPrice || sale.pricePerItem || 0); // Ensure price is a float.
    const totalSale = quantity * price;
    const category = normalizeCategory(sale.productCategory || sale.category);
    const date = sale.saleDate || new Date().toISOString(); // Default to current date if missing.

    normalizedSales.push({
        product: productName,
        category: category,
        quantity: quantity,
        unitPrice: price,
        totalSale: totalSale.toFixed(2), // Format total sales to two decimal places for currency.
        saleDate: new Date(date).toISOString().split('T')[0] // Format date to YYYY-MM-DD.
    });
}

// Output the array of normalized sales data.
// This can then be sent to a database, spreadsheet, or reporting tool.
return [{
    json: {
        reportData: normalizedSales
    }
}];

This code block acts as a diligent data librarian, meticulously organizing and cleaning incoming data into a consistent, unified format.

// received sensor data as a JSON object.

const sensorData = items[0].json; // Access the incoming sensor data from the first item.

const temperatureThreshold = 35.0; // Define the critical temperature threshold in Celsius (e.g., for a machine).
const currentTemperature = parseFloat(sensorData.temperature); // Convert the incoming temperature to a float.
const deviceId = sensorData.deviceId || 'Unknown Device'; // Get the device ID, or default if missing.

let alertTriggered = false;
let message = `Device ${deviceId} - Temperature: ${currentTemperature}°C.`; // Default status message.

// Check if the current temperature exceeds the defined threshold.
if (currentTemperature > temperatureThreshold) {
    alertTriggered = true; // Set alert flag to true.
    message = `🚨 ALERT: Device ${deviceId} - Temperature (${currentTemperature}°C) exceeds critical threshold of ${temperatureThreshold}°C! Immediate action may be required.`;
    console.warn(message); // Log a warning to the n8n console for debugging and visibility.
} else {
    message = `Device ${deviceId} - Temperature: ${currentTemperature}°C (Normal). All systems nominal.`;
}

// Output the processed data, including the original sensor data, the threshold,
// whether an alert was triggered, and a status message.
// Subsequent nodes can then use 'alertTriggered' to conditionally send notifications.
return [{
    json: {
        deviceId: deviceId,
        currentTemperature: currentTemperature,
        threshold: temperatureThreshold,
        alertTriggered: alertTriggered,
