The Merchant Sheets add-in installs free from Microsoft Marketplace. Once it's installed, a Merchant Sheets tab appears in the Excel ribbon. Your plan is billed on merchantsheets.com, never through Microsoft.
Supported versions of Excel
The add-in works in these versions of Excel:
Excel for Microsoft 365 on Windows
Excel for Microsoft 365 on Mac, and Excel 2019 or later for Mac
Excel on the web
Install from the web app
In the web app, go to Overview.
On the Get the Excel add-in card, select Get the add-in.
Follow the prompts to open Excel and add Merchant Sheets.
Install from inside Excel
On the Home tab, select Add-ins.
Search for Merchant Sheets.
Select Merchant Sheets, then select Add.
Review the permissions and select Continue. The Merchant Sheets tab appears in the ribbon.
After you install
The add-in stays installed for your Microsoft account, so the Merchant Sheets tab shows in every workbook. Next, sign in to the add-in with your Merchant Sheets account.
If Merchant Sheets doesn't appear in Add-ins
Work and school Microsoft accounts can have Marketplace add-ins turned off by an IT admin. Ask your admin to allow Merchant Sheets, or to deploy it from the Microsoft 365 admin center under Integrated apps. For other install or loading problems, see The add-in will not load or sign in.
