Why is content pasted from Google Docs badly formatted?

When you paste from Google Docs, Notion, Word or a web page, the clipboard carries that app's hidden formatting. The editor keeps what it can, but some of it does not translate cleanly.

Import the document instead

1. Export your document as .docx, .md or .html. In Google Docs, use File > Download.
2. On the Posts page, open the Import posts menu and choose Import from file.
3. Pick the file. Superblog creates a draft from it, with its images optimised.

Paste markdown

If your text is in markdown, use the /markdown widget. It converts the whole document cleanly. See Add widgets to a post.

Images from Google Docs

Images pasted from Google Docs point to Google's servers, which stop serving them after a few days. Download the images and upload them again, or import the document as above.
