ETL vs ELT – Explained Using Apple Juice analogy! 🍎🧃
We often hear about ETL and ELT in the data world — but how do they actually apply in tools like Excel and Power BI?
Let’s break it down with a simple and relatable analogy 👇
✅ ETL (Extract → Transform → Load)
🧃 First you make the juice, then you deliver it
➡️ Apples → Juice → Truck
🔹 In Power BI / Excel:
You clean and transform the data in Power Query
Then load the final data into your report or sheet
💡 That’s ETL – transformation happens before loading
✅ ELT (Extract → Load → Transform)
🍏 First you deliver the apples, and make juice later
➡️ Apples → Truck → Juice
🔹 In Power BI / Excel:
You load raw data into your model or sheet
Then transform it using DAX, formulas, or pivot tables
💡 That’s ELT – transformation happens after loading
