Publishing from Lightroom Classic to Squarespace, or via SmugMug

Publishing from lightroom Classic to Squarespace? As a travel photographer, currently publishing to SmugMug using theSmugmug  plugin, I now plan to publish on Squarespace and would require that all the country folders, city folders and galleries, together with the titles, captions and metadata are moved to Squarespace directly, or from SmugMug. Has anyone accomplished this effectively, and if so I would appreciate any pointers that you can share. Thanks, 

Adrian
