Stock News Sentiment Automation using Gemini AI, Google Sheets & Gmail
Stock News Sentiment Automation using Gemini AI, Google Sheets & Gmail This workflow automatically fetches daily stock market news, analyzes sentiment using Gemini AI, calculates impact scores, sends alerts for high-impact news and stores structured results in Google Sheets. Quick Implementation Steps Import the workflow into your n8n account Configure the Market News API (HTTP Request node) Add your Google Gemini API credentials Connect Google Sheets and create required columns Configure Gmail node (add recipient email) Activate the workflow What It Does This workflow runs every day at 8 AM and automatically collects the latest stock market news from a public API. It filters, cleans and processes the data to ensure only relevant and unique articles are analyzed. Each news article is sent to Google Gemini AI, which classifies the sentiment as bullish, bearish or neutral, along with a confidence score and reasoning. The workflow then calculates an impact score based on sentiment and confidence. High-impact news is immediately flagged and sent via email alerts, while all processed results are stored in a structured format in Google Sheets for tracking and analysis.
