About This File

Package for working with JSON.  Uses high-speed text parsing, rather than building an intermediate representation as with prior LabVIEW JSON libraries (this is much faster).  Allows easy working with "subitems" in JSON format, or one can convert to/from LabVIEW types.  Uses the new "malleable VIs" of LabVIEW 2017 to convert to any LabVIEW type directly.

JSON text makes use of a form a JSON Path notation, allowing easy and rapid access to the subitems of interest.

Requires LabVIEW 2017 and install by VIPM 2017 or later.
