hi - I often copy/paste from Obsidian to Google Docs. For example, I write a status report in Obsidian and copy/paste subsections of the document into a Google Doc.
I used to set it in Reading mode, select, and copy/paste. With exception of the font type and size, I had to do no adjustments. Bold was bold, Italic was Italic, URLs were hyperlinks in Google Docs.
This seemed to have changed since the upgrade to version 1.x. The format is no longer preserved.
