# CSV Files in Excel When working with CSV files and special characters, such as the **German *****Umlaute***, one has to be careful with opening those files in Excel, as often the special characters are not transformed correctly and are saved as such. This results in wrong formatting when uploading the CSV to a Locoia flow or any other system. As a solution, one should use [Sublime Text](https://www.sublimetext.com/) to handle such files and open them and then **Save with Encoding** > **UTF-8 with BOM**. This should preserve the "Umlaute" when you now open the CSV with Excel. ![Sublime - Save with Encoding - for encoding issues Excel](https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/48052589882/original/zKFyneCbtM1LTPkEJymrcqwhlbZtsSoRbg.png?1596648730) Also see encoding for [AWS S3 files](/connectors/connectors/s3-aws.md#s3-utf-8-content-type-encoding-of-files). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
