Tutorials: JSON Processing

The following tutorials are aimed at complimenting the existing documentation around the JSON PARSE and JSON GENERATE statements, with which you can convert JSON text to COBOL data formats (JSON PARSE) and generate COBOL data to JSON text (JSON GENERATE).

• The first tutorial, Generating JSON output, uses a COBOL program containing a data structure to generate a JSON text output file. It includes a number of techniques on how to manipulate the process to affect the output text.
• The second tutorial, Parsing a JSON text string, uses a JSON text file to populate a COBOL data structure. It demonstrates a number of ways that the data is matched up, and also a number of steps you can take to help troubleshoot matching problems.

With JSON being a popular format for data interchange, especially in today's web applications, the ability to handle it in your COBOL programs is very beneficial.
