JSON Validator

Provides a function, jsonvalidator_isvalid(), that validates text in JSON format.  It returns true if the text contains a well-formed JSON structure; false, otherwise.  If the text is null or blank, false is returned; this is consistent with a!fromJson.

Note: This function validates only syntax, not the actual data against a JSON schema.

This plugin has been tested in Appian 18.2, 18.1 and 17.4 but will most likely work in newer as well as older Appian versions using Java 7 or higher.
