sample not working?

[tonipohl]

That's a cool demo for Excel UDF, but in my case, Excel doesn't accept the formula. I deployed the web with the adapted web URLs, tried to upload the manifext.xmls in Excel Online and desktop with a shared folder, but it does not work. Excel Desktop (Build 9001.2138) shows the "Custom functions sample" taskpane (not visible in Excel online), but that's it. Am I missing something? Thx!

same for me. excel is not initializing the function when i host the script and html locally (no matter if http or https). the local url is available in browser and html and script is online but when side-loading the manifest locally via shared folder it does not initialize the function. url in the manifest is set right!
