Hi Lauren -
You can't use just any excel file for importing information back into Cvent. You'll probably need to download and populate an "import template" file. Here's an article that walks you through that process:
https://support.cvent.com/s/communityarticle/Importing-Internal-Information-Answers?is_article=true&lang=en_US&searchFor=internal%20field
Tip: The template will probably include more fields than you want to import in, so be sure to select "Do Not Import" for any fields where you don't want it pulled into your import. If you pull in a field and it is blank in that column, it may override data in the contact record, which you don't want to do.
Once the import is completed, you should be able to run a report to confirm that your data has been imported back in.
Hope this helps!
