In this paper, we present the JSON Stats Analyzer, a free-to-use open-source web-based JavaScript tool and module that provides JSON document analysis. We explain how the JSON Stats Analyzer works, its usage alongside the demonstration of eleven JSON documents from Tier 1, Tier 2 and Tier 3 from our proposed taxonomy that categorizes JSON documents according to their size, content, redundancy and nesting characteristics. For each JSON document, we provide its definition, characteristics and the document structure, alongside a visual representation of the JSON document structure and its summary statistics.
