The sheet already includes all the i18n data to be converted to any language, but no one has made a conversion of the translation file to Español yet... If you are interested/capable, I would be more than happy to assist you with the conversion. Basically you just need to take the es.json text file and update the English to Español. I've helped with other translations. It's fairly straight forward. Once the conversion is done, we'll upload the new es.json to roll20's repo and after the weekly update cycle, anyone with their roll20 language set to Spanish will see the sheet in Español. PM me if you are interested. Cheers
