You want to use the tools in the Spreadsheet Inquire add-in for Excel, but you don't see the Inquire tab in the Excel ribbon. You first need to turn on the Inquire add-in.
Click File > Options > Add-Ins.
Make sure COM Add-ins is selected in the Manage box, and click Go.
In the COM Add-Ins dialog box, make sure the box next to Inquire Add-in is selected.
Note If you don't see an entry for Inquire Add-in in the COM Add-Ins dialog box, it's because either your version of Office or Excel doesn't include it, or your organization's system administrator has made it unavailable. Microsoft Office Professional Plus 2013 includes the Inquire add-in for Excel.
After the add-in is turned on, the Inquire tab will appear in Excel.
