Your Excel template includes the required materials in a tab called 'ESEF hypertags', right after your 'General Data ESEF' one. If your file does not include the mentioned tab it means that you are running an outdated version. Contact our Customer Support and we will be happy to prepare your materials so you are able to perform Block Note tagging.
You can update your Excel template and include the ESEF Hypertags tab by yourself. Find the instructions here.
