Replace not working in Excel Online

[twoheadGH]

Hi,
I installed the Firefox Addon Auto Text Expander, but I was forwarded to this Chrome github project. However, it is not working in Excel Online. Could you fix this, please?

Just wanted to share a bit of context — it looks like this issue happens because Excel Online runs inside a very restricted, sandboxed environment. Its web editor blocks extensions from injecting or modifying text, which is why Auto Text Expander can’t work there.

This isn’t a problem with the add-on itself but rather a limitation on Excel Online’s side. Thought this might help clarify things!
