I have existing custom function created in Com Add-in. To support MAC and online I am creating a web Add-in. I have included the equivalent add-in in the manifest. but the web add-in does not recognize the custom function created in com add-in when the same workbook opened on browser/mac instead it throws #Name? and displays the namespace used in com add-in.
<EquivalentAddins>
<EquivalentAddin>
<ProgId>xxx.Office.Formulas</ProgId>
<Type>COM</Type>
</EquivalentAddin>
Custom function used in com Add-in template "=get("data").
Custom function displayed on Browser "=@xxx.Office.Formulas.get("data")"
