Is it possible to download Export To Excel from APP Store and using it on Web 8?

I want to export search result on CME to an excel file.

I found Export To Excel on SDL AppStore, but it's Supported products is blank and I cannot download it.

How can I download 'Export To Excel'?

And is it possible to use 'Export To Excel' on Web 8?

I have posted same question to Stack Exchange,  and a respondent says  'Export To Excel'  can be used on SDL Web 8.5.

My post to Stack Exchange is following.
