JSON Crack vs JSONBuddy

JSON Crack is a free online tool for turning JSON, YAML, CSV, and XML into graph or tree views. Users can supply data through an editor, a file upload, or a URL, then export visualizations as PNG, JPEG, or SVG. It also converts between formats, formats JSON, and validates JSON, YAML, and CSV. Developers can generate TypeScript interfaces, Go structs, Rust serde, and JSON Schema; schema utilities validate schemas, create mock data, and generate schemas from supported data formats. Other tools include JWT decoding, data randomization, jq execution, and JSONPath commands. A VS Code extension provides visualization in the editor, and embedding options include an iframe widget, postMessage API, and jsoncrack-react package. The maker says editor data is processed in the browser and not stored on its servers, while its privacy policy allows usage-data and cookie collection and possible Google Analytics use. The stated capacity is approximately 300 KB, varying with data complexity and hardware. Premium features have moved to ToDiagram.com; prior subscribers can use the same credentials there.

JSONBuddy provides tools for editing, validating, formatting, transforming, and automating JSON and JSON Schema work. Its Windows editor offers text and grid views, schema-aware completion, and validation results. Schema tools include authoring assistance, reference navigation, diagnostics, debugging, analysis, tests, and documentation. Validation checks JSON syntax and schema constraints, with reports linking failing data to relevant rules. The product converts among JSON, CSV, XML, and HTML, including CSV imports and JSON-to-CSV output. Streaming validation can process large JSON without loading the entire document into memory; streaming JSON Schema validation through -jsv requires a JSONBuddy Large Data license. Windows command-line tools support repeatable checks in scripts and CI, and the published Core API v1 supports formatting, minifying, JSON Patch, validation, and schema documentation. ValBuddy CLI performs file operations locally on Windows and can return selected diagnostics to an AI agent, though selected content or diagnostics may be sent to its model provider. Licenses include free personal and educational use and paid perpetual options, starting at $15 for JSONBuddy Swift. The portable package requires 64-bit Windows 10 or 11.
