CSV Header Extractor

Version: 17.07

Supported Since: 17.07

What is CSV Header Extractor Processor?

CSV Header Extractor processing element can be used to extract the header row of the CSV payload in a message context. The same functionality can be obtained by the Extract CSV Row processing element by providing 0 as the parameter but this processing element provides better performance to extract header/first row compared to the Extract CSV Row processing element.

The CSV payload is expected to be in the RFC 4180 standard format.

In order to use this processing element, you must first select the CSV Message dependency from the processor list when you are creating an empty Ultra project. If you have already created a project, you can add this dependency via Component Registry. From Tools menu, select Ultra Studio → Component Registry and from the Processors list, select the CSV Message dependency
