Once You Have A Pivot Table Complete

Diving into the world of pivot tables can feel like unlocking a secret weapon for data analysis. Once you've mastered the art of creating one, a whole new realm of possibilities opens up. The initial pivot table is just the foundation; the real power lies in how you manipulate, refine, and extract insights from it. This article explores the vast landscape of post-pivot table analysis, providing practical techniques and strategies to transform raw data into actionable intelligence.

Understanding Your Pivot Table Foundation

Before embarking on advanced manipulations, it's crucial to understand the anatomy of your pivot table. This foundation will dictate how effectively you can leverage its capabilities.

• Rows and Columns: These areas define the categories you're analyzing. Rows typically represent the primary dimension, while columns provide a secondary breakdown.
• Values: This is where the calculations happen. You can sum, average, count, or perform other aggregations on your data.
• Filters: Filters allow you to focus on specific subsets of your data, enabling targeted analysis.
• Report Filter (Page Field): Similar to filters, but allows you to select a single item to display the pivot table for.

Refining Your Pivot Table: Mastering the Basics

Once your pivot table is built, several basic adjustments can significantly enhance its clarity and usefulness.

1. Sorting and Filtering Data

• Sorting: Click on any column header to sort the data in ascending or descending order. This is helpful for identifying top performers or outliers.
• Filtering: Use the filter arrows in the row and column labels to include or exclude specific categories. You can also apply value filters to show only records that meet certain criteria (e.g., sales greater than $10,000).
• Label Filters: Filter based on the labels themselves. For example, show only products that start with the letter "A."
• Value Filters: Filter based on the aggregated values. For example, show only regions with total sales exceeding a certain threshold.

2. Grouping Data

Grouping allows you to combine similar items into broader categories. This is particularly useful for dates, numbers, and text fields with many unique values.

• Grouping Dates: Right-click on a date field and select "Group." You can group by days, weeks, months, quarters, or years. This is invaluable for trend analysis.
• Grouping Numbers: Group numerical data into ranges. For example, group sales figures into brackets of $1000.
• Grouping Text: Manually group text items with similar characteristics. This is useful for categorizing products or customers.

3. Customizing Calculations

The "Values" area offers a range of calculation options beyond simple sums.

• Summarize Values By: Right-click on a value field and select "Summarize Values By." Choose from options like Sum, Count, Average, Max, Min, Product, etc.
• Show Values As: This powerful feature allows you to display values as percentages, differences from base items, running totals, and more. Right-click on a value field and select "Show Values As."
  • % of Grand Total: Shows each value as a percentage of the overall total.
  • % of Column Total: Shows each value as a percentage of its column total.
  • % of Row Total: Shows each value as a percentage of its row total.
  • Difference From: Compares each value to a base item, showing the difference.
  • % Difference From: Compares each value to a base item, showing the percentage difference.
  • Running Total In: Calculates a running total within each category.
  • % Running Total In: Calculates a running percentage total within each category.
  • Rank Smallest to Largest/Largest to Smallest: Ranks items based on their values.

4. Formatting Your Pivot Table

Visual appeal is important for clear communication.

• PivotTable Styles: Choose from a variety of pre-defined styles to quickly format your pivot table. These styles control colors, fonts, and borders.
• Manual Formatting: Use the standard Excel formatting tools to customize the appearance of specific cells, rows, or columns.
• Number Formatting: Format numerical values to display currencies, percentages, or decimal places as needed.

Advanced Pivot Table Techniques: Unleashing the Power

Beyond the basics, these advanced techniques will help you extract even deeper insights from your data.

1. Calculated Fields and Items

Calculated fields allow you to create new columns in your pivot table based on formulas. Calculated items let you create new row or column labels based on formulas.

• Calculated Fields: Go to "PivotTable Analyze" tab, click "Fields, Items, & Sets," and select "Calculated Field." Enter a name for the field and a formula using existing fields. For example, calculate profit margin by subtracting cost from revenue.
• Calculated Items: Go to "PivotTable Analyze" tab, click "Fields, Items, & Sets," and select "Calculated Item." Enter a name for the item and a formula using existing items in the row or column field. This is less commonly used but can be helpful in specific scenarios.
• Caveats: Calculated fields can sometimes be slow to calculate, especially with large datasets. They also don't always behave as expected with certain types of aggregation.

2. Slicers and Timelines

Slicers and timelines provide interactive filtering options that make it easy to explore different segments of your data.

• Slicers: Go to "PivotTable Analyze" tab and click "Insert Slicer." Choose the fields you want to use as slicers. Slicers are visual filters that allow you to quickly select multiple items at once.
• Timelines: Similar to slicers, but specifically designed for date fields. Go to "PivotTable Analyze" tab and click "Insert Timeline." Timelines allow you to filter data by years, quarters, months, or days.

3. Pivot Charts

Visualizing your pivot table data with charts can reveal patterns and trends that might not be obvious in the raw numbers.

• Creating a Pivot Chart: Go to "PivotTable Analyze" tab and click "PivotChart." Choose the chart type that best represents your data (e.g., column chart, line chart, pie chart).
• Chart Customization: Use the chart tools to customize the appearance of your chart, add titles, labels, and legends.
• Interactive Charts: Pivot charts are linked to the underlying pivot table, so any changes you make to the pivot table will automatically update the chart.

4. Power Pivot and Data Modeling

For complex data analysis involving multiple tables, Power Pivot is a game-changer. It allows you to create relationships between tables and build more sophisticated pivot tables.

• Activating Power Pivot: In Excel, go to "File" -> "Options" -> "Add-Ins." In the "Manage" dropdown, select "COM Add-ins" and click "Go." Check the box next to "Microsoft Power Pivot for Excel" and click "OK."
• Data Modeling: Import data from multiple sources into Power Pivot and create relationships between tables based on common fields.
• DAX Formulas: Power Pivot uses DAX (Data Analysis Expressions) formulas, which are more powerful than standard Excel formulas. DAX allows you to perform complex calculations and create custom measures.
• Benefits: Power Pivot can handle much larger datasets than standard pivot tables and allows you to analyze data from multiple sources in a single pivot table.

5. "GetPivotData" Function

This function allows you to extract specific values from a pivot table into a separate cell. This is useful for creating custom reports or dashboards.

• Syntax: =GETPIVOTDATA(data_field, pivot_table, [field1, item1], [field2, item2], ...)
• Example: =GETPIVOTDATA("Sales", $A$1, "Region", "East", "Product", "Widget") This formula retrieves the sales for the East region for the Widget product from the pivot table starting in cell A1.
• Flexibility: The GETPIVOTDATA function is dynamic. If the underlying pivot table changes, the values returned by the function will automatically update.

6. Using VBA for Pivot Table Automation

For repetitive tasks or complex manipulations, VBA (Visual Basic for Applications) can be used to automate pivot table operations.

• Recording Macros: Start by recording a macro to capture the steps you want to automate. Then, you can edit the macro code to customize it.
• VBA Code Examples:
  • Refreshing a Pivot Table: ThisWorkbook.Sheets("Sheet1").PivotTables("PivotTable1").RefreshTable
  • Changing a Filter: ThisWorkbook.Sheets("Sheet1").PivotTables("PivotTable1").PivotFields("Region").CurrentPage = "East"
  • Creating a Pivot Table: This requires more extensive code and is best learned through tutorials and examples.
• Benefits: VBA automation can save significant time and effort, especially when dealing with large or complex pivot tables.

Real-World Applications: Putting It All Together

Let's explore some practical examples of how to use these techniques to solve real-world business problems.
