Difference between quoted strings and non quoted single words in CSV file

Question

Can anyone explain why in some CSV's translations are not always in " ".

For example in the tax csv:

Tax,Tax

Shouldn't it be:

"Tax","Tax"

Answer 1

For translation containing one word you can write without quotes but both works. If your translation contains many words you have to put them in quotes.

Exemple :

 Tax,Tax
 "Subtotal","Subtotal"
 "Gift Card","Gift Card"
