About this tutorial
How to get stock data in Claude starts with a problem most analysts run into fast: Claude is a powerful reasoning tool, but it has no live market data on its own. This live session shows you exactly how to bridge that gap by pairing Claude with MarketXLS in Excel or Google Sheets, so you can feed real, current stock data into your AI prompts and get analysis that is actually grounded in numbers. What you'll see: - How to pull live price, volume, and fundamental data into Excel using MarketXLS functions like mxp() and mx_income_statement(), then format it as clean text Claude can read - A step-by-step walkthrough of copying a structured data snapshot from your spreadsheet and pasting it into a Claude prompt to get instant ratio analysis and plain-language summaries - How to build a reusable Excel template with a dedicated output cell that auto-formats ticker data, sector, P/E, dividend yield, and revenue growth into a single prompt-ready block - A live comparison of asking Claude about a stock with no data versus feeding it a MarketXLS data dump, so you can see exactly how much the output quality improves - How to use Claude to flag outliers or anomalies in a multi-stock watchlist you built in Excel, turning a 20-row MarketXLS table into a ranked shortlist in seconds - A quick look at automating the copy-paste step using Excel formulas that concatenate data fields into a prompt string you can drop straight into Claude or any other AI tool This matters because the biggest limitation of using AI for stock research is not the AI itself, it is the data. Claude can reason, compare, and explain at a high level, but if you feed it stale or missing information you get confident-sounding answers built on nothing. MarketXLS solves the data side by connecting directly to live market feeds inside your spreadsheet, and once that data is structured correctly, Claude becomes a genuinely useful research assistant rather than a hallucination risk. Together the two tools cover the full workflow: MarketXLS handles data retrieval and organization, Claude handles interpretation and summarization. For individual investors, financial analysts, and portfolio managers who already live in Excel, this combination adds an AI reasoning layer without requiring any coding, API keys, or data engineering.
