Yes, it's possible to translate it. But right now it does not have the language tags needed for this, the wiki have more information on them . The Shadow of esteren sheet code can be found here . Example of a character sheet with these translation tags. If you: make a copy of the HTML file follow the guide on the wiki page to change it Create manually the default translation file or have someone with Pro account generate it make a copy of the translation file named "fr.json" and edit it to french If you manage to come this far or to at least most of the things above, you will likely find someone to help with the rest and/or get these changes committed to Github, or you can look at how it works yourself . Good Luck!
