Hi Markus,
I observed data processing results where displayed columns contained space characters. I would expect that such data should be handled as text strings then.
Double quotes in CSV files do not give any information on the data type of a value. Instead, they merely ensure that the data can be correctly parsed. If the pipe symbol is used as separator, there is no need to enclosed whitespaced string by quotes.
Do you possibly have a processor that interprets the syntax of the incoming CSV data to detect and assign data types?
Best, Christian
