, Introduction
n8n is an open source workflow automation platform that allows you to connect applications, APIs, and services using a visual, node based interface. It helps automate data movement, system integration, and repetitive tasks without the need for complex code. n8n is widely used because it is flexible, supports self hosting, integrates with hundreds of tools, and gives developers full control over logic, execution, and data handling, making it a strong alternative to closed automation platforms.
In this article, we will learn about the top 7 n8n workflow templates for data science. These templates are plug and play, meaning all you have to do is provide your data with the Model API or Database API. Everything else is already tried and tested, allowing you to focus on analysis, experimentation, and results rather than building a workflow from scratch.
, 1. Automate fundamental stock analysis with FinHub data and Google Sheets (DCF calculator)

This n8n workflow automates the most time-consuming parts of fundamental equity research by converting raw financial filings into institutional grade analysis with no execution costs.
It pulls six years of annual and quarterly data from FinHub, cleans and structures the financials, calculates accurate trailing twelve month figures, calculates three-year and five-year compound annual growth rates, and runs a full discounted cash flow valuation to estimate the intrinsic stock value.
All historical data, growth trends and valuation results are automatically delivered to a connected Google Sheets dashboard with charts and tables that populate instantly for fast, objective analysis.
, 2. Automated stock technical analysis with xAI Grok and multi-channel notifications

This workflow is designed for stock traders, financial analysts, portfolio managers, and investment enthusiasts who want automated, data-driven stock market analysis without manual charting.
It runs daily to analyze selected stocks using technical indicators such as Relative Strength Index and Moving Average Convergence Divergence, generate clear buy, sell or hold signals, and enhance the results with AI based interpretation and market news.
Insights are automatically delivered via email, messaging apps, and Google Sheets logs, making it ideal for anyone who wants consistent trading signals, daily market summaries, and centralized tracking across multiple stocks.
, 3. Process OCR documents from Google Drive into a searchable knowledge base with OpenAI and Pinecone

This workflow automates the complete retrieval augmented generation ingestion pipeline for document indexing. When a new OCR JSON file is added to a Google Drive folder, it automatically extracts text metadata, cleans and parses the Arabic text, breaks the content into semantic pieces, generates AI embeddings, and stores them in the Pinecone vector index for retrieval.
Once processing is complete, the file is moved to an archive folder to prevent duplicate ingestion. Setup is simple and requires connecting Google Drive, OpenAI and Pinecone credentials for embedding, then configuring input and archive folder paths before running the workflow.
, 4. Consolidate data from 5 sources for automated reporting with SQL, MongoDB, and Google tools

This workflow automatically consolidates data from Google Sheets, PostgreSQL, MongoDB, Microsoft SQL Server, and Google Analytics into a single master Google Sheet on a scheduled basis.
Each dataset is tagged with a unique source identifier to maintain traceability, then merged, cleaned and standardized into a consistent structure ready for reporting and analysis.
The result is a centralized, always-updated reporting hub that eliminates manual data collection, reduces cleaning effort, and provides a reliable foundation for business insights across multiple systems.
, 5. Automated Data Extraction (Products, Jobs, Articles and More) with Zyte AI

This workflow provides an automated AI powered web scraping solution that extracts structured data from e-commerce sites, articles, job boards, and search engine results without the need for custom selectors.
Using the Zyte API, it automatically detects page structure, handles pagination, retries errors, and aggregates the results through a two-step crawling and scraping process to produce a clean CSV export, even for large websites.
Users simply enter a target URL and select a scraping target, while advanced logic routes the request to the correct extraction model. Manual mode is also available for users who prefer raw data output and custom parsing.
, 6. Customer Feedback Automation with Sentiment Analysis using GPT-4.1, Jira and Slack
Link to template: Customer Feedback Automation with Sentiment Analysis using GPT-4.1, Jira and Slack | n8n workflow template
This workflow automates the entire customer feedback lifecycle by collecting submissions via webhooks, validating the data, and using OpenAI to analyze sentiment.
Negative feedback and feature requests are automatically converted to Jira issues, while invalid submissions trigger instant Slack alerts for quick action. In addition to real-time processing, the workflow generates a weekly OpenAI-powered summary of all feedback related to Jira tickets and delivers it to Slack, giving teams a clear view of customer sentiment trends without manual review.
, 7. Real-Time Sales Pipeline Analytics with Bright Data, OpenAI, and Google Sheets
Link to template: Real-Time Sales Pipeline Analytics with Bright Data, OpenAI, and Google Sheets | n8n workflow template
This workflow automatically tracks key sales pipeline metrics like new leads, deal stages, win rates, and closed opportunities to keep teams informed about revenue health.
It connects to your CRM on a schedule, analyzes pipeline data with OpenAI to detect risks and anomalies, sends actionable alerts and summaries to Slack, and stores daily snapshots in Google Sheets for trend analysis. The result is a fully automated sales visibility system that removes manual CRM exports and helps sales leaders, operations teams, and reps act faster and forecast more accurately.
, final thoughts
n8n has thousands of templates that can automate almost any data science workflow. The main thing is to know which ones are actually useful, easy to plug in and proven in real use. The seven templates listed above are some of the most practical choices for data science because they cover the entire pipeline from data collection to analysis to distribution.
You can use them to automate financial analysis, generate technical business insights, turn OCR documents into searchable knowledge bases, consolidate data from multiple databases for reporting, extract structured data from the web without building custom scrapers, analyze customer feedback with sentiment and issue tracking, and monitor sales pipelines in real-time with alerts and dashboards.
If you want to move faster without constantly rebuilding the same tooling, these workflows are a strong starting point. Connect your data source, add your model or database credentials, and start iterating over the logic. You’ll spend less time on setup and more time on results.
