> Key: CSV-253
> URL: https://issues.apache.org/jira/browse/CSV-253
> Project: Commons CSV
> Issue Type: Improvement
> Components: Parser
> Reporter: Lars Bruun-Hansen
> Priority: Major
> Attachments: 2019-10-30 20_31_39-Apache Commons CSV 1.8-SNAPSHOT API.png, \

> The parser must be able to handle absent values in input and translate that into \
> {{null}} as required. I see several tickets on this matter in the history, but none \
> seem to have addressed the issue, at least not for parsing.  For this problem, I \
>                 see a need to introduce a new term:
> Definition: _Absent value_ is when there are zero characters between field \
> delimiters. Specifically the aim is to be able to parse the following:
> {noformat}
> "John",,"Doe"    // 2nd element is absent
> ,"AA",123        // 1st element is absent
> "John",90,       // 3rd element is absent
> "",,90           // 2nd element is absent (1st element isn't)
> {noformat}
> 
> See also CSV-93 which I think never addressed the issue, probably because the \
> reporter was happy with having the issue fixed for CSV output, not for parsing. A \
> PR is coming...
