@Hundasuupa Does the add-in work with older versions Excel? if so, how far back is it supported?

Is it or would it be possible to download the add-in as an Excel Add-in file (.xlam)? - so that compatibility with older versions of excel can be explored - specifically I’m wondering if it would work with Excel 2013 which does support Add-ins but only if you have the file locally on your pc (not via shop-style management which is found in Excel 365).

Retail Excel is not supported, only web excel and 365 subscription desktop clients.

The add-ins from the shop, and the Eve addin aren’t COM/.dll’s like in previous excel versions (AFAIK, I’m not used to having had to use add-ins in excel before this project)  
Instead they are run via Javascript, using the office-js library, so it’s essentially a website that can hook into Excel.

There were some issues with properly detecting the compatibility with the rich data features used by the add-in, and we’ve just got the confirmation about compatibility with retail Excel, so even 2019/2021 excel sadly can’t use the add-in either.
