# [Unified manifest for Microsoft 365](#tab/jsonmanifest)

The following example shows how to specify both a COM add-in and an XLL add-in as equivalents in a unified manifest. Often you specify both. For completeness, this example shows both equivalents in context. They're identified by their [`"alternates.prefer.comAddin.progId"`](/microsoft-365/extensibility/schema/extension-alternate-versions-array-prefer-com-addin#progid) and `"alternates.prefer.xllCustomFunctions.filename"` respectively. For more information on COM add-in compatibility, see [Make your Office Add-in compatible with an existing COM or VSTO add-in](../develop/make-office-add-in-compatible-with-existing-com-add-in.md).
