Add KoreDefo to Excel

KoreDefo is not yet listed in Microsoft's official add-in store, so you add it to Excel directly using the steps below. It takes about 5 minutes.

Requirements: Excel in Microsoft 365 (Windows desktop, Mac or Excel on the web). Perpetual-license versions such as Excel 2019 and earlier are not supported.

Before you start: save the add-in file (.xml) from our email to your PC. If you have not received the email yet, start a free trial. After you sign up, we email you your license key and a download link for the add-in file.

Open Excel

Open the workbook you want to check. Any workbook will do.

Click "Add-ins"

On the ribbon at the top, open the Home tab and click Add-ins, near the right end.

Note: in some versions of Excel, the button is Get Add-ins on the Insert tab instead. If you can't find it, check both tabs.

Click "More Add-ins"

In the panel that opens on the right, click More Add-ins near the bottom.

Switch to the "My Add-ins" tab

In the dialog that opens, select the My Add-ins tab at the top.

Click "Upload My Add-in"

Click the Upload My Add-in link in the top-right corner of the dialog.

Don't see it? See "If Upload My Add-in doesn't appear" below.

Select the file you downloaded

Choose the file koredefo-excel-add-in.xml that you saved earlier and upload it. If you saved it from the link in our email, it is usually in your Downloads folder.

Click the KoreDefo icon

The KoreDefo icon appears on the right side of the Home tab. Click it to open the KoreDefo task pane on the right.

Enter your license key

Paste the license key from your sign-up email into the Paste your license key box in the task pane, then click Apply. You're ready to go.

Using a Mac
Excel for Mac may not show Upload My Add-in. If it doesn't, add KoreDefo in one of these two ways.
· The easy way: follow the steps above in Excel on the web (in Safari or another browser) and use KoreDefo there.
· In Excel for Mac: (1) Quit Excel (⌘Q). (2) In Finder, choose Go > Go to Folder… and open ~/Library/Containers/com.microsoft.Excel/Data/Documents/wef (if there is no “wef” folder, create one with that name inside the “Documents” folder one level up). (3) Put the koredefo-excel-add-in.xml file you saved into that folder. (4) Open Excel and choose KoreDefo from Add-ins on the Home tab (it is listed under Developer Add-ins).
Note: in Excel for Mac, the add-in doesn't show the free-trial sign-up button. Please sign up on this page instead.

If Upload My Add-in doesn't appear
· Personal Microsoft 365 (Personal / Family): desktop Excel does not show Upload My Add-in for personal accounts. This is how Microsoft designed it. Follow the same steps in Excel on the web (Home > Add-ins > More Add-ins > My Add-ins > Upload My Add-in) and use KoreDefo there. We are preparing a listing in Microsoft's official add-in store.
· Work or school account: your organization may restrict which add-ins you can add. Ask your IT administrator.
