All roads lead to Excel. When you try to make a nice dashboard in Jira that incorporated custom fields and all the data was normalized, nope - they send out an excel spreadsheet every time. They do this to any tool you try to use as a group tool to update things - like Confluence. Before you know it it's back in Excel again and you have multiple sources that keep getting lost.
If data is structured enough to be put in a dashboard, it is structured enough to drive automated tools that make the dashboard redundant.
Excel is the modern equivalent of the back of a napkin. It is inescapable.
