In Excel, save your list as CSV and upload it under Sanvador Store Locator → Import / Export. Column headers in English, Turkish and several other languages are recognised, and missing categories are created for you. Run a test import first: it shows exactly what will be added or changed before anything is saved.
Opening hours can be written in a single column, for example Mo-Fr 09:00-18:00; Sa 10:00-14:00; Su off. Day names in English, Turkish, German, French and Spanish are understood.
