Welcome to the ODK forum, @Shams! We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a picture as your avatar because it helps build community!

Please note that Central is now the ODK server and that Aggregate has not been supported since May 2021. Please see this post for more details:

Aggregate is no longer being updated

In accordance with the plans announced at Upcoming changes to Aggregate, the core team is no longer updating Aggregate. We will not fix bugs, add features, review PRs, improve documentation, release new versions, or answer support questions. We've been communicating this reality to users over the last two years through the documentation, code repo, and in community announcements. The core team (and the @TAB) believe that Central is production ready and better than Aggregate for most users, so …

A quick look at your form indicates that it is not an XForm (which is why legacy ODK Aggregate will be complaining...)

Perhaps you just exported your spreadsheet out of MS Excel as an XML file? That unfortunately doesnt work. Instead you probably need to run your (presumably) XLSForm spreadsheet thru, say, XLSForm Online to convert it into a proper XForm XML, and then try uploading that into your Aggregate server.

That aside, as already indicated, ODK Aggregate is long since unsupported, so I would also highly recommend you migrate your forms to a current alternative, specifically ODK Central or possibly KoboToolbox, both of which you can self-host if desired.
