Double quotes in CSV files do not give any information on the data type of a value.
I came along software applications which would need the usage of double quotes for the distinction that provided data should be handled as text strings.
Instead, they merely ensure that the data can be correctly parsed.
I suggest to reconsider this view a bit more for some data imports.
If the pipe symbol is used as separator, there is no need to enclosed whitespaced string by quotes.
How do you think about to avoid the interpretation of a column delimiter character within strings as a CSV separator?
Do you possibly have a processor that interprets the syntax of the incoming CSV data to detect and assign data types?
Occasionally, yes.
