Webflow character limit on header size / Schema Markup

I’m using Webflow for our simple site. The header incl. Json Schema FAQ markup.

Now Webflow is telling me there’s a 10.000 character limit for the header - and it counts spaces, too. In consequence I have to pick and choose the questions/answers for the markup.

Any easy - non coder - way to load a .txt or .Json file with the markup through a script tag or similar? I can place a txt in the Webflow Asset upload section. It doesn’t allow .json, so I’d have to find CDN alternatives, if required.

I read SRC doesn’t work because Google‘s test tool requires it to be inline.

Help would be appreciated.
