Click on "Import" in the lower section of the left sidebara. Alternatively, in the Mac app, you can choose File > Import... from the menu bar.
Select the Google Drive option.
You have the option to import a single file or multiple files. In both cases you'll download the files from Google drive. We recommend using the .html format, but also support .md, .docx or .txt.
Pick the destination channel in Slite (where you want your import to live)
You'll receive a notification when the import is complete!
