Step 2: Insert a Pivot Table
1. Select your information range. 2. Go to the Insert tab on the ribbon. 3. Click on PivotTable. 4. In the Create PivotTable dialog box, choose where you desire to set the PivotTable (New Worksheet or Existing Worksheet) and click OK.
Step 3: Add Fields to the Pivot Table
1. In the PivotTable Field List, drag the field you desire to analyze (e. g., Customer ID) to the Rows area. 2. Drag the same battleground to the Values country. By default, Excel will sum the values, but you involve to alter this to count unequaled values.
Step 4: Change the Value Field Settings
1. Click on the drop down arrow next to the field in the Values area. 2. Select Value Field Settings. 3. In the Value Field Settings dialog box, choose Count from the Summarize value field by list. 4. Click OK.
Note: The default "Count" function in Excel counts all occurrences, not singular values. To count unique values, you require to use a different approach, such as create a help column or using Power Pivot.
Step 5: Use Power Pivot for Count Unique
For more progress users, Power Pivot offers a straightforward way to count unequalled values:
1. Go to the Power Pivot tab on the ribbon. 2. Click on Manage to exposed the Power Pivot window. 3. In the Power Pivot window, click on Design and then Add Column. 4. Use the DAX (Data Analysis Expressions) formula to make a new column that counts unique values. for instance, if your field is nominate Customer ID, you can use the formula:=DISTINCTCOUNT([Customer ID]). 5. Close the Power Pivot window and retrovert to your Pivot Table. 6. Add the new column to the Values country of your Pivot Table.
