Definition of Pivot Tables
A pivot table is a tool used to sort, reorganize, group, count, total, or average data in spreadsheets. A pivot table is a feature in spreadsheet software that allows you to summarize and analyze large datasets. It enables you to transform and reorganize data by summarizing it according to different categories, such as date, product, or location, and displaying it in a more manageable format. Pivot tables are particularly useful for analyzing data that contains multiple categories and numerical values, allowing you to easily identify patterns and trends. With a pivot table, you can quickly answer complex questions about your data and gain insights that would be difficult to obtain otherwise.
Four Basic Parts of a Pivot Table
A pivot table has four basic parts: rows, columns, values, and filters.
A pivot table consists of four basic parts:
- Rows: This section lists the categories or labels by which you want to group and display your data horizontally.
- Columns: This section lists the categories or labels by which you want to group and display your data vertically. Similar to rows, columns can be pulled directly from the data set or created using values. Values are used to calculate and count data. This is where you input the variables you want to measure. This is also how you create calculated fields in your pivot table. A calculated field is a new field within a pivot table that carries out certain calculations based on the values of other fields.
- Values: This section lists the numerical data that you want to summarize in your pivot table. The values can be summarized using functions such as sum, count, average, and more.
- Filters: This section allows you to filter your data by selecting specific criteria, such as dates or categories — just like filters in regular spreadsheets!
By using these four basic parts of a pivot table, you can organize, analyze, and summarize large amounts of data in a flexible and customizable way. This will also will allow you to compare different metrics from your data and execute calculations, which will help you gain valuable insights.
Using pivot tables for analysis
Pivot tables can be a useful tool for answering specific questions about a dataset so you can quickly share answers with stakeholders.
Here’s a real-life scenario where a data analyst could use pivot tables:
Imagine a marketing analyst at a retail company needs to analyze the sales data for different products across different regions. The analyst has a large dataset containing information on product sales, regions, and dates.
Instead of making changes to the original spreadsheet data, the marketing analyst used a pivot table to answer these questions and easily compare the sales revenue of the products sold in each region.
To analyze this data, the analyst can use pivot tables to:
- Create a pivot table with rows for each product and columns for each region.
- Add the total sales values as the values field in the pivot table.
- Filter the data by date range to analyze sales for a specific time period.
- Add a slicer to filter the data by product category, such as electronics or apparel.
- Create a pivot chart to visualize the sales data by region and product.
Using pivot tables, the marketing analyst can quickly identify which products are selling well in which regions, and how the sales trends vary over time. The analyst can also drill down into the data by adding additional rows or columns to the pivot table or by creating multiple pivot tables with different filters and settings. This information can help the retail company make data-driven decisions on product inventory, marketing strategies, and sales promotions
Pivot tables are an effective tool for data analysts working with spreadsheets because they highlight key insights from the spreadsheet data without having to make changes to the spreadsheet.

Overall, pivot tables are a powerful tool for analyzing large datasets and gaining insights that can help you make better decisions.
How to Create a Pivot Table
To create a pivot table in spreadsheet software, follow these steps:
- Start with the data: Before creating a pivot table, make sure your data is organized in a table format with column headings. Unclean and Disorganized data will make your pivot table analysis incorrect – which will also affect your decision-making.
- Select the data range: Highlight the range of data that you want to use in your pivot table. This can be done by clicking and dragging your mouse over the data.
- Insert a pivot table: In the “Insert” menu, select “Pivot Table.” This will open a new dialog box where you can select the data range you want to use.
This pop-up menu will appear.
There is an option to select New sheet or Existing sheet and a Create button. Generally, you will want to create a new sheet for your pivot table to keep your raw data and your analysis separate. You can also store all of your calculations in one place for easy reference. Once you have created your pivot table, there will be a pivot table editor that you can access to the right of your data.
- Choose fields for the pivot table: In the “Pivot Table Fields” pane, select the fields you want to include in your pivot table. You can drag and drop fields into the “Rows,” “Columns,” and “Values” sections to create the table layout.
- Customize the pivot table: Once you’ve added fields to your pivot table, you can customize the layout, formatting, and calculation options. You can also add filters, sort data, and group data by specific categories.
- Refresh the pivot table: If you make changes to your original dataset, you can update the pivot table by clicking “Refresh” in the “Pivot Table Analyze” tab.
- Save the pivot table: Once you’ve created and customized your pivot table, make sure to save it so you can refer to it later or share it with others.
Understanding Pivot Table Features
Pivot tables offer several features that can help you analyze and summarize large datasets. Here are some of the key features to understand:
- Sorting Data: You can sort your pivot table by any of the fields you’ve selected, either in ascending or descending order. This can help you identify trends and patterns in your data more easily.
- Filtering Data: You can use filters to narrow down the data displayed in your pivot table based on specific criteria. This can help you focus on specific subsets of your data and analyze it in more detail.
- Grouping Data: You can group data in your pivot table by specific categories, such as date or location. This can help you identify trends and patterns across different groups of data.
