Remove Claude’s formatting from Notion
Notion discards pasted HTML, so Claude's class names do not survive into a Notion page. What does survive is character-level: zero-width characters, exotic spaces, smart quotes and em dashes. Paste as plain text with Ctrl+Shift+V (Cmd+Shift+V), or paste normally and then check for invisible characters.
Check yours first. Paste the text into the free checker and it lists every artifact with its exact position — no account, nothing uploaded, unlimited.
Check my text →What Notion keeps
- Notion converts pasted HTML into its own block format, so provider class names do not survive.
- Zero-width characters and exotic spaces do survive, because they are text rather than markup.
The fastest fix
Paste as plain text with Ctrl+Shift+V (Cmd+Shift+V), or paste normally and then check for invisible characters.
There is no markup to remove here, so the characters are the whole problem. Zero-width characters, non-breaking and exotic spaces and smart punctuation are text rather than formatting, which is why they survive a route that strips everything else.
How to check it worked
Export the page as Markdown & CSV and open the file in a text editor. Notion's own view will not show you invisible characters.
