Handling data type in JSON

FileMaker 16 introduced a collection of built-in functions for manipulating data serialized as JSON. This makes it easier for FileMaker applications to interact with many web services. This will also make JSON the de facto standard format for scripts within FileMaker to pass parameters and results to each other, improving code sharing within the FileMaker community.

JSON does not have a broad palette of scalar data types to choose from: text, number, boolean, and null. Even with those, FileMaker's JSONGetElement function always returns a text result, even when the serialized JSON value is a number or boolean. So I made a handful of custom functions and scripts for sending and receiving typed data with JSON.

The module is hosted on GitHub, or you can download it directly.
