1. Core Concept: What AutoFilter Does & How It Works
AutoFilter temporarily hides rows that do not meet your business criteria, allowing you to focus on a specific segment of data without modifying the source table:
Hides rows that fail conditions. The data is still there, just hidden.
Rearranges visible rows in sequence (A-Z, Largest-Smallest).
Clearing a filter immediately restores 100% of hidden records.
2. 🔥 Live Interactive — Basic Department Filter
Task: Select Sales from the Department dropdown to show only Sales staff. Then switch between Finance, HR, and All:
| Employee | Department | Sales Amount |
|---|---|---|
| Amit | Sales | ₹45,000 |
| Rahul | Sales | ₹58,000 |
| Arjun | Sales | ₹62,000 |
3. 🔥 Live Practice — Number Filters (> ₹30,000 / < ₹20,000 / Between)
Task: Filter orders by numeric thresholds:
| Order ID | Customer | Sales Amount |
|---|---|---|
| ORD003 | Rahul | ₹42,000 |
| ORD004 | Neha | ₹31,000 |
| ORD006 | Karan | ₹67,000 |
4. Text Filters: City & Product Segmentation
Filter by geographic territory and purchased item:
| Customer | City | Product |
|---|---|---|
| Amit | Mumbai | Laptop |
| Rahul | Mumbai | Monitor |
| Karan | Mumbai | Webcam |
5. Practical Business Use: Multi-Column AND Logic

| Order ID | Region | Product | Sales Amount |
|---|---|---|---|
| ORD101 | West | Laptop | ₹55,000 |
| ORD105 | West | Laptop | ₹60,000 |
6. Multi-Condition Slicing: Sales Dept + Sales > ₹50,000
| Employee | Department | Sales Amount |
|---|---|---|
| Rahul | Sales | ₹58,000 |
| Arjun | Sales | ₹62,000 |
7. Chronological Intervals: Date Filters
Filter transactions by time intervals:
| Order ID | Customer | Order Date | Sales Amount |
|---|---|---|---|

| ORD005 | Arjun | 27-Mar-2026 | ₹15,000 |

8. Combining Filter + Sort in Harmony
Filter narrows down the visible universe; Sort organizes the visible records from highest to lowest revenue:
| Order ID | Region | Product | Sales Amount |
|---|---|---|---|
| ORD105 | West | Laptop | ₹60,000 |
| ORD101 | West | Laptop | ₹55,000 |
| ORD103 | West | Monitor | ₹12,000 |

| Amit | Sales | ₹45,000 |
| Rahul | Sales | ₹58,000 |
| Arjun | Sales | ₹62,000 |
