If you just need to present the links from an Excel, custom info will be enough to automate that. Those will be presented as text however, not clickable links. The text can be copy-pasted though.
If you want hyperlinks specifically, you can use the Javascript API to do that (https://society.solibri.com/topic/620/javascript-api-documentation-solibri-version-9-10-8/2) Reading Excel files is a bit more difficult in Javascript though, so that might become a barrier. Using Javascript is also less stable, as we don’t focus in testing its compatibility between as much as we do for the Java API.
If you implement the URL reading from the Excel in Java custom information, it is possible that in some future that info can be used in a hyperlink template as output, making it possible to have the url as a hyperlink instead of just text.
