Importing into Tess from an Excel Spreadsheet

I am in the info - gathering phase of a potential project.

We are running a few virtual programs (Shakespeare Reading Group, Hour long Q and A with artists). 

We are asking our patrons to register for these virtual events through a Wu-Foo form or the Zoom platform. Their name, address, email, etc the dumped into an excel spreadsheet.

Is the Constituent Import Utility the right tool I would use to get these names out of excel and into Tess with a PID#? Also, how would you recommend I mark these patrons as attending one of these virtual programs?  I was thinking of making the source of the newly created records "Virtual" or something, then I could do a mass upload of a CSI or attribute....???

Right now, it is too big of a lift to "sell" these events through TNEW, but I would be interested in learning about how other organizations maybe do it via TNEW. Have the patron register in TNEW v6. or 7, and then make it work for the Zoom invitation and such.

Thank you,

Jessica
