Encoding issues in CSV files often occur when the file's delimiter (e.g., comma, semicolon, tab) does not match the expected delimiter in your software. This can cause all data to appear in a single column rather than being split into multiple columns.

Common Causes:

1. Incorrect Delimiter: The file uses a different delimiter than expected (e.g., semicolon instead of comma).
2. Encoding Mismatch: The file's character encoding (e.g., UTF-8, ANSI) is incompatible with the software, leading to misinterpretation of separators.
3. Improper Export: Export settings may not align with the software's import expectations.

Solution:
Ensure the correct delimiter and encoding settings are selected during import. For example, choose "UTF-8" and specify the appropriate delimiter (comma, semicolon, etc.) in the import options.
