What commenters say

• Excel's handling of CSV files is problematic due to its use of locale settings for parsing, which can lead to incorrect imports.
• The default behavior of Excel when opening CSV files can be improved by using the 'import' feature instead of simply opening the file.
• Some argue that CSV is a flawed format that should be replaced with alternative formats, while others see it as a simple and effective solution for data exchange.
• The use of UTF-8 BOM can help ensure that Excel recognizes the encoding of a CSV file, but it can also cause issues with other applications.
• Localization issues can cause problems when working with CSV files, particularly when using Excel, and can lead to subtle errors that are difficult to spot.
• Some commenters have had positive experiences with alternative spreadsheet software, such as LibreOffice Calc, which handles CSV files more effectively than Excel.
• The importance of specifying encoding when importing CSV files is emphasized, as relying on automatic detection can lead to errors.
• Some argue that Excel's behavior when handling CSV files is intentionally designed to be inconvenient, while others see it as a result of backwards compatibility and legacy issues.
