Issue Summary

This is reproducible on Data Center: Yes

Steps to Reproduce

1. Link a few issues - on some issues, add only one issue link, and on different issues, link multiple issues
2. Create a JQL to filter these issues
3. Either:
   • In the issue search in the Jira UI
     • Make sure that the Links column is selected
     • Click on the Open in Microsoft Excel icon
   • Using Excel
     • Install and open the Jira Cloud plugin
     • Select the import type JQL query
     • Add the JQL query you created
     • Click on Get Data Now
4. Check the Linked Issues column

Current behavior

In the resulting XLSX file, if an issue is linked to a single issue, a clickable link appears in the "Linked Issues" column. If multiple issues are linked, none of the issues are clickable. You end up with a plain text value delimited by a comma or semicolon (JRA-123,JRA-7 for example, or JRA-123;JRA-7)

Expected behavior

All issues listed under the "Linked Issues" column of the downloaded XLSX file should be clickable links.

Workaround

Currently, the only workaround would be to use the option with Google Sheets and download the file as an xlsx.
Exporting to Google Sheets, the hyperlink on the lines with multiple issue keys is a JQL with the issue keys.
