🛠️ Step-by-Step: How to Create a Pivot Table

Step 1: Prepare Your Data Table

• Make sure there are no blank rows or blank columns inside your data range.

Step 2: Insert Pivot Table

1. Click anywhere inside your data table.
2. Go to the Insert tab on the top ribbon.
3. Click PivotTable (or press shortcut Alt + N + V + T).
4. Choose New Worksheet and click OK.

Step 3: Arrange Fields in the PivotTable Field List

Drag and drop your column fields into the 4 Pivot Table areas:

• Rows: Drag fields you want to group by (e.g., Category or Salesperson).
• Values: Drag numerical fields you want to calculate (e.g., Sales Amount). Excel will automatically apply SUM.
• Columns: Drag fields to split data horizontally (e.g., Year or Region).
