About Jsoncrack.com
JSON Crack is an open-source application for visualizing structured data. It turns JSON, YAML, XML, and CSV into interactive graphs or trees that can be viewed in dark or light mode. The GitHub repository contains the code for the web app, browser and editor extensions, and a reusable React component.
You can load data to explore its structure, format and validate JSON, YAML, and CSV, and convert between formats such as JSON to CSV or XML to JSON. The tool can also create JSON Schema and validate against it, generate TypeScript interfaces, Go structs, Kotlin data classes, and Rust serde types, and run jq and JSONPath queries. Visualizations can be downloaded as PNG, JPEG, or SVG files, and all processing happens locally.
It suits developers and others who work with APIs, configuration files, or data files and need to inspect structure. It also suits contributors who want to run the project locally or integrate the visualizer through the available extensions and npm package.
