How To Process 1000+ Excel Rows as Data Source With Microsoft Copilot Studio (Complete Guide)

📌 SharePoint vs Microsoft Copilot Studio: Which Agent Handles Excel Files Better? 💡 Stop struggling with limited data access from your online Excel files. I tested two different agent approaches to see which one actually works when you need to process large datasets - and the results will surprise you. What you'll discover in this complete comparison test: ⚡ Two Agent Approaches Tested: Watch me put a SharePoint site agent head-to-head against a Microsoft Copilot Studio agent with custom agent flows. One uses direct file access, the other uses specialized table actions with pagination settings. 🛠️ What Each Agent Can Actually Do: • Process Excel files with 150+ rows vs 1000+ rows • Calculate date ranges across entire datasets • Handle cross-file operations and comparisons 📋 Live Testing Process: See me run identical prompts on both agents using real Excel files. I test file length recognition, data calculations across entire sheets, and complex operations between multiple files. 🎯 Real Examples You'll See: • Setting up SharePoint site agents with direct file access • Building Copilot Studio agents with custom agent flows • Configuring pagination settings to handle 10,000+ rows • Testing with files containing 152 lines vs 1,001 lines • Comparing accuracy on date calculations and task counting Each test reveals which approach actually works when you need reliable data from large Excel files in business automation. 🔒 The Winning Solution: One agent consistently delivered accurate results while the other failed basic calculations. The winner also integrates directly into Power Automate flows for complete automation. I'm using GPT-5 with generative orchestration here, plus specialized table actions that most people don't know how to configure properly for large datasets. The breakthrough comes from embedding list rows actions within agent flows instead of using them as standalone tools. This unlocks pagination settings that change everything. You'll see exact configuration steps - from SharePoint document library setup to the agent flow design that handles massive Excel files without breaking. Ready to handle large Excel files in your agents without hitting data limits? Watch me test both approaches and reveal which one actually works for business automation. 💬 Got other business automation ideas you'd like me to create videos about?
