Hi Peter
Thanks for posting in the community. Unfortunately Lucidchart does not currently support a Sitemap specific import function from a spreadsheet file.

I'm also looking to do this in Lucid Chart - I think I might have a way of doing it using nested unordered lists.
We're going to write a script that runs through a list of URL's and using the / as a way of setting up different levels it'll create a un-ordered list that you can then paste into the Lucidchart sitemap popup.
If it's of interest - let me know.
Cheers
Neil
