This workflow automatically downloads a CSV from the web, and parses it in a format that n8n can access. It then ensures that the data from the CSV is matched to the names of the columns in the database, and inserts this data as new rows in Snowflake.

Prerequisites:

  • A CSV with data
  • A Snowflake account and credentials
  • A Snowflake database to upload your CSV to

Nodes:

  • A HTTP Request node to download the CSV file
  • A Spreadsheet File node to access the data from the CSV
  • A Set node to ensure the data from the CSV is mapped to the column names of the Snowflake database
  • A Snowflake node to insert these new rows into the database.

This n8n workflow demonstrates a basic data loading process into Snowflake, transforming data from a generic HTTP request into a structured format before ingestion.

What it does

This workflow performs the following steps:

  1. Manual Trigger: Starts the workflow manually when "Execute workflow" is clicked.
  2. HTTP Request: Makes a generic HTTP request to an unspecified endpoint. This node is typically used to fetch raw data from an external API or service.
  3. Edit Fields (Set): Transforms the data received from the HTTP request. This node is used to manipulate the data structure, rename fields, or add new properties, preparing it for the next steps.
  4. Spreadsheet File: Converts the processed data into a spreadsheet file format (e.g., CSV, Excel). This step is often used when Snowflake expects data in a file-based format for bulk loading.
  5. Snowflake: Loads the data (likely the spreadsheet file from the previous step) into a Snowflake database. This node handles the connection to Snowflake and the execution of the data loading operation.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Snowflake Account: Access to a Snowflake database and the necessary credentials (configured as an n8n Snowflake credential).
  • API/Service Endpoint: An external API or service that the "HTTP Request" node can connect to and retrieve data from.

Setup/Usage

  1. Import the workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Snowflake credential within n8n.
  3. Configure HTTP Request:
    • Edit the "HTTP Request" node to specify the URL, method, headers, and any other parameters required to fetch your data.
  4. Configure Edit Fields (Set):
    • Adjust the "Edit Fields (Set)" node to transform the data according to your needs and the target Snowflake table schema.
  5. Configure Spreadsheet File:
    • Ensure the "Spreadsheet File" node is configured to output the data in a format compatible with Snowflake's loading capabilities (e.g., CSV).
  6. Configure Snowflake Node:
    • Edit the "Snowflake" node to specify the database, schema, table, and the loading method (e.g., COPY INTO command if loading from a file).
  7. Execute the workflow: Click "Execute workflow" to run the process manually.

Automate Reddit brand monitoring & responses with GPT-4o-mini, Sheets & Slack

How it Works This workflow automates intelligent Reddit marketing by monitoring brand mentions, analyzing sentiment with AI, and engaging authentically with communities. Every 24 hours, the system searches Reddit for posts containing your configured brand keywords across all subreddits, finding up to 50 of the newest mentions to analyze. Each discovered post is sent to OpenAI's GPT-4o-mini model for comprehensive analysis. The AI evaluates sentiment (positive/neutral/negative), assigns an engagement score (0-100), determines relevance to your brand, and generates contextual, helpful responses that add genuine value to the conversation. It also classifies the response type (educational/supportive/promotional) and provides reasoning for whether engagement is appropriate. The workflow intelligently filters posts using a multi-criteria system: only posts that are relevant to your brand, score above 60 in engagement quality, and warrant a response type other than "pass" proceed to engagement. This prevents spam and ensures every interaction is meaningful. Selected posts are processed one at a time through a loop to respect Reddit's rate limits. For each worthy post, the AI-generated comment is posted, and complete interaction data is logged to Google Sheets including timestamp, post details, sentiment, engagement scores, and success status. This creates a permanent audit trail and analytics database. At the end of each run, the workflow aggregates all data into a comprehensive daily summary report with total posts analyzed, comments posted, engagement rate, sentiment breakdown, and the top 5 engagement opportunities ranked by score. This report is automatically sent to Slack with formatted metrics, giving your team instant visibility into your Reddit marketing performance. --- Who is this for? Brand managers and marketing teams needing automated social listening and engagement on Reddit Community managers responsible for authentic brand presence across multiple subreddits Startup founders and growth marketers who want to scale Reddit marketing without hiring a team PR and reputation teams monitoring brand sentiment and responding to discussions in real-time Product marketers seeking organic engagement opportunities in product-related communities Any business that wants to build authentic Reddit presence while avoiding spammy marketing tactics --- Setup Steps Setup time: Approx. 30-40 minutes (credential configuration, keyword setup, Google Sheets creation, Slack integration) Requirements: Reddit account with OAuth2 application credentials (create at reddit.com/prefs/apps) OpenAI API key with GPT-4o-mini access Google account with a new Google Sheet for tracking interactions Slack workspace with posting permissions to a marketing/monitoring channel Brand keywords and subreddit strategy prepared Create Reddit OAuth Application: Visit reddit.com/prefs/apps, create a "script" type app, and obtain your client ID and secret Configure Reddit Credentials in n8n: Add Reddit OAuth2 credentials with your app credentials and authorize access Set up OpenAI API: Obtain API key from platform.openai.com and configure in n8n OpenAI credentials Create Google Sheet: Set up a new sheet with columns: timestamp, postId, postTitle, subreddit, postUrl, sentiment, engagementScore, responseType, commentPosted, reasoning Configure these nodes: Brand Keywords Config: Edit the JavaScript code to include your brand name, product names, and relevant industry keywords Search Brand Mentions: Adjust the limit (default 50) and sort preference based on your needs AI Post Analysis: Customize the prompt to match your brand voice and engagement guidelines Filter Engagement-Worthy: Adjust the engagementScore threshold (default 60) based on your quality standards Loop Through Posts: Configure max iterations and batch size for rate limit compliance Log to Google Sheets: Replace YOURSHEETID with your actual Google Sheets document ID Send Slack Report: Replace YOURCHANNELID with your Slack channel ID Test the workflow: Run manually first to verify all connections work and adjust AI prompts Activate for daily runs: Once tested, activate the Schedule Trigger to run automatically every 24 hours --- Node Descriptions (10 words each) Daily Marketing Check - Schedule trigger runs workflow every 24 hours automatically daily Brand Keywords Config - JavaScript code node defining brand keywords to monitor Reddit Search Brand Mentions - Reddit node searches all subreddits for brand keyword mentions AI Post Analysis - OpenAI analyzes sentiment, relevance, generates contextual helpful comment responses Filter Engagement-Worthy - Conditional node filters only high-quality relevant posts worth engaging Loop Through Posts - Split in batches processes each post individually respecting limits Post Helpful Comment - Reddit node posts AI-generated comment to worthy Reddit discussions Log to Google Sheets - Appends all interaction data to spreadsheet for permanent tracking Generate Daily Summary - JavaScript aggregates metrics, sentiment breakdown, generates comprehensive daily report Send Slack Report - Posts formatted daily summary with metrics to team Slack channel

Automate financial transaction tracking with Gmail, GPT, Notion & Telegram alerts

📩 Automatically Log Transactions from Gmail into Notion and Get Telegram Alerts Who’s it for This workflow is for individuals or entrepreneurs who receive bank alerts, invoices, and payment emails in Gmail and want them to be automatically organized in Notion — while also receiving quick Telegram notifications for each transaction. If you manage personal or business finances and find it tedious to manually record every debit, credit, or invoice — this automation does it all for you. --- How it works The workflow acts as an AI-powered Accountant Agent that reads incoming Gmail messages and decides whether each email represents a Debit Transaction, Credit Transaction, Debit Invoice, or Credit Invoice. The Gmail Trigger watches your selected inboxes (like forwarding@bayesian-labs.com, support@bayesian-labs, anoop.karnik@bayesian-labs). The Classifier (GPT-5-nano) determines the correct transaction type. The appropriate Agent (GPT-5) then extracts amount, currency, and description details. The Agent uses Notion API tools to log structured data into your Personal Finance System Notion template (Financial Transactions & Income databases). Finally, a Telegram notification is sent summarizing the entry (From, To, Subject, Snippet). In short: every time your bank emails you — Notion gets updated, and you get notified. --- How to set up Duplicate the Personal Finance System Notion template into your workspace. Create a Telegram Bot with BotFather → copy the bot token and your chat ID. Generate an OpenRouter API key for GPT-5 / GPT-5-nano. Create a Notion Integration Token and connect it to your duplicated finance databases. Add your Gmail accounts (forwarding@, support@, and/or personal Gmail) under Gmail OAuth2 credentials in n8n. Import the workflow JSON into n8n → fill in the credential names as listed below: n8ncloudregular_usage → OpenRouter Notion account → Notion API Accountant AI → Telegram Bot Gmail OAuth2 for each inbox trigger Once active, n8n polls Gmail every minute, classifies emails, updates Notion, and sends Telegram updates. --- Requirements n8n instance (self-hosted or cloud) Gmail accounts connected via OAuth2 OpenRouter API key Telegram bot token & chat ID Notion integration token Your duplicated Personal Finance System Notion template --- How to customize the workflow You can extend this workflow to: Track credit card statements, subscriptions, or payroll notifications. Add Slack or WhatsApp alerts alongside Telegram. Include live FX rates for USD→INR conversion using an API node. Connect Google Sheets as a backup ledger or export target. Add error-handling branches to mark Gmail messages as processed or label them “Logged to Notion”.
