Hey Frances thanks for posting! We currently do not support Mindjet import. If this is something you would like to see in Lucidchart please fill out this Feature Request form to let our Product Managers know!

I want to import Mindjet Mindmaps. It's been over a year since the last request. Can we do this yet?

Hi Karl Thanks for reaching out. It is not presently possible to import Mindjet Mindmaps into Lucidchart. To promote it to our development team add it to the feature request form. Thanks!
