Have you tried my Spreadsheet Import Tool yet? Found in the Exchange, and also here:

> Now [in the Ignition Exchange](https://inductiveautomation.com/exchange/2660/overview). While waiting on IA review, i Interested parties can also get this here: [https://www.automation-pros.com/SpreadsheetImportTool/](https://www.automation-pros.com/SpreadsheetImportTool/) I intend to publish at this link as well as in the Exchange going forward. Announcements will be in this topic. (:

I haven't thoroughly tested in 8.3, but I'd love to have feedback on that.

(It can create both the devices and the corresponding UDT instances for you.)
