I don't get the article: if you want to copy sexps in JSON why don't you just use JSON lists mapping simbols to strings? e.g.

    (p "Paragraph text here, " (b "bold text"))

becomes

    ['p','paragraph text here, ',['b','bold text']]

where space become commas, and '()' become '[]'.

The json example form html formatting is willingly verbose without reason to be.
