The Data tab in the Excel ribbon is where you’ll find the data analysis button. Usually found in the Analysis group, adjacent to the buttons for sorting and filtering. You can add the button by customising the ribbon if it is not currently visible. Go to the File tab, choose Options, and finally click Customise Ribbon to accomplish this. Click OK after checking the box next to the Data Analysis option in the list on the right. The Data tab should now display the button.
