This looks on topic, and most of the site is in English except "Documento". My suggestion is to wait until Monday and post it again but using a title in English

This looks on topic, and most of the site is in English except "Documento". My suggestion is to wait until Monday and post it again but using a title in English and a comment explaining you are the author also in English. Post in other languages are usually ignored or flagged. Perhaps with a title like "JSONScope - Interactive JSON viewer" or some variant that makes more sense. (The stile of your comment is also too informal [Hi form Argentina!]. It's not necessary to be super formal and serious here, but I think less informal language may be better.)
