Leading and trailing spaces may affect formatting.

Duplicate items can make lists unnecessarily long.
Review Special Characters
Ensure commas inside values are handled appropriately if the data will be imported into other systems.
Common Mistakes to Avoid

Accidental blank lines can create empty entries.

Adding a space after each comma often improves readability.
