Pivot tables are one of the most useful tools in Excel for summarizing and analyzing data. Pivot tables are built off a table or a dataset and can summarize rows or columns. When you have a pivot table that contains dates, you can group it according to months. This helps in organizing the table and in helping understand the table better.
Note: The dates in the source table must be formatted as dates so that Excel can extract the month.
Step 1 – Summon the menu
– Select any cell in the pivot table
– The PivotTable Analyze menu is displayed on the menu bar

Step 4 – Check the result
