LIBJSON: Stata module to provide Mata class library for obtaining and parsing JSON strings into object trees


  • Erik Lindsley



The libjson class (library) is designed to be called from the Mata environment to perform tasks related to obtaining a JavaScript Object Notation (JSON) formatted response from the file or website URL (via a REST API). Most users will want to write an ado file that employs the libjson object to do all the heavy lifting, with the final tailoring of the output to be handled by the ado file.
