jaq vs JSON Crack

jaq is a free jq clone for querying and transforming data, available as both a command-line replacement and a Rust library for compiling and running jq programs. Alongside JSON, it handles YAML, CBOR, TOML, XML, CSV, and TSV, and can convert between those formats while applying a jq filter. Its jaq-core library supports multithreaded use and data types beyond JSON. jaq also accepts arbitrary values as object keys and can process strings containing arbitrary bytes, including invalid UTF-8. The project publishes benchmarks comparing jaq with jq and gojq, and reports faster results on many benchmarks. It states that jaq is memory-safe and prevents input data or filters from initiating I/O, although filters may read files before execution. The project also warns that it does not guard against resource exhaustion, so processing may use unlimited time, memory, or stack space. Binary downloads and installation instructions are provided for Linux, macOS, and Windows, and an online playground is available. jaq is MIT-licensed.

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.
