You don't. If you don't want someone modifying the contents of your file, you need to store the contents in a container that can be password protected.

A CSV file is just a text file, so there is no mechanism for adding a password.

You could try one of the following instead:

1. Encrypt the file using checksums to determine it has been modified.

2. Store the file in a restricted folder

3. Use something like winzip or 7-zip to store the file in compacted format with a password on the zip.

4. Store the data in an Excel file that is password protected

5. Store the data in a local database that is password protected (e.g. Access, LocalDb, SQLite)

There may be other options but that's all I can think of at the moment
