Remove Claude’s formatting from Google Slides
Google Slides preserves pasted HTML, so copying straight from Claude carries its class names — the ones containing “claude” — into a slide deck. They are invisible while you read, but present in the source and readable by anyone who looks. Paste with Ctrl+Shift+V (Cmd+Shift+V) to paste without formatting.
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 Google Slides keeps
- Slides keeps pasted formatting and the underlying markup, the same way Docs does.
- Decks get exported to PDF and PowerPoint and forwarded widely, so anything left in the text travels further than it does in a document you keep.
The fastest fix
Paste with Ctrl+Shift+V (Cmd+Shift+V) to paste without formatting.
That handles the markup. It does not handle zero-width characters, non-breaking and exotic spaces, smart quotes or em dashes — those are text rather than formatting, so they survive the paste route above and every other one.
How to check it worked
File → Download → Microsoft PowerPoint (.pptx), rename to .zip and read the slide XML. Slides has no source view of its own.
