Excel into Confluence Data Center to reflect weekly updates

[Tiffany J]

I have an excel file that gets new data added or updated weekly.  What is the easiest process to add this file to a confluence pages with each weeks updates?  I know how to add the file manually each week.  I'm hoping there is some sort of automation to grab the updated file, maybe at a set time, each week and display only the newest version of data.  I'm looking to do this on confluence data center not cloud.  And in this space 3rd party add-ons would take years to get approved for use.
