Pivot tables let you analyze large amounts of data and narrow down large data sets to see the relationships between data points. Google Sheets uses pivot tables to summarize your data, making it easier to understand all the information contained in your spreadsheet.

Where a regular spreadsheet uses only two axes—columns and rows—pivot tables help us make sense of the information in your spreadsheet by summarizing any selected columns and rows of data. For example, a pivot table could be used to analyze sales brought in by divisions of a company for a specific month, where all the information is randomly entered into a dataset.
Creating a pivot table from the information in the picture above displays a neatly formatted table with information from selected columns, sorted by division.
