jq vs JSONBuddy

jq is a free command-line processor for selecting and transforming JSON data. A jq filter takes an input and produces output; filters can be combined to access nested attributes, construct objects, gather results into arrays, or make other transformations. It reads whitespace-separated JSON values and writes serialized results separated by whitespace. Each expression runs on each input value and may produce zero or more outputs. For very large inputs, the --stream option parses incrementally. Output options include compact, raw, ASCII, sorted-key, and colored forms. Written in portable C, jq has no runtime dependencies, and a standalone binary can be copied to another machine of the same type. Standalone executables are available for Linux, macOS, and Windows, with packages listed for Linux distributions and package managers including Homebrew, MacPorts, winget, Scoop, and Chocolatey. A Docker image is also available. Release binaries have SHA-256 checksums, and signed release artifacts use jq release keys. The code is licensed under MIT; the documentation uses CC-BY-3.0.

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.
