The Problem: Excel's Hard Limits
Excel's Maximum Limits:
- 1,048,576 rows (hard ceiling - can't exceed)
- 16,384 columns (XFD column)
- Performance degrades severely above 100K rows
- 32-bit version crashes with files >2GB
Real-World Excel Pain:
📊 Sales data: 2 years of transactions = 5M rows → Can't open in Excel
📊 Web analytics: 1 year of clickstream = 50M rows → Excel crashes
📊 IoT sensor data: 1 month = 100M rows → Impossible in Excel
📊 Customer database: 10M records with history → Excel freezes
