It is not really clear what you are trying to achieve.

• If the Excel file is the source file that you are going to localize using Passolo then you need the Database parser add-in that contains an Excel component to localize this file.
• If the Excel file is just a source for existing translations that you want to leverage into your project, then change the first line into the correct language code (docs.rws.com/.../language-ids) and save it as a tab delimited Unicode text file. This file then can be added as a glossary to your environment and used to pre-translate your project.
