Hi @NVV

You can try using the symbol to wrap the html content

{
"description":`# This is demo
asdlala

asfladflkjaldf

`
}

Hey @NVV

You see the errors because you’re missing quotes around the store name and the description.

As an example:

Wrong: “name”: Not Very Vanilla,

Correct: “name”: “Not Very Vanilla”,

It looks like Spider Free SEO Optimizer is generating that code so you’ll either want to talk with them about resolving the issue or choose a different app for your structured data.

Hope that helps but if you have any other questions, let me know.
