Troubleshooting

“I saved it but it’s not an XML file”

  • When saving, make sure the filename ends with .xml

  • If it saved as manifest.xml.txt, rename it to manifest.xml

“I don’t see Upload My Add-in”

  • This is common on Excel 2021 not signed in

  • Use Option B (Shared Folder / Trusted Add-in Catalog) instead

“Trusted Add-in Catalogs is missing”

  • Some installations/policies hide it

  • In that case, you’ll need your IT/admin to deploy the add-in (Microsoft 365 org deployment), or use a signed-in Excel option.
