JSON Crack is a Visual Studio Code extension that renders interactive graphs from textual data. Despite its name it supports multiple formats, including YAML, TOML and XML. Unlike Mermaid and D2, where the textual form is a means to create a specific visual graph, JSON Crack is a tool to look at data that happens to be in a textual format. The layout algorithm works well and the tool allows selective hiding of branches and nodes, making it a great choice for exploring data sets. A companion web-based tool is also available, but our reservations about relying on online services for formatting or parsing code apply. JSON Crack does have a node limit, and directs users to a commercial sibling tool for handling files with more than a few hundred nodes.
