JSONBuddy

What JSONBuddy is

JSONBuddy is a toolkit for editing and managing JSON and JSON Schema. Its Windows editor offers text and grid views, schema-aware completion, and validation results. The schema editor provides tools for authoring, navigating references, diagnosing, debugging, analyzing, testing, and documenting schemas. Validation checks both JSON syntax and schema constraints, and points to the relationship between invalid data and the relevant schema rules. JSONBuddy also converts among JSON, CSV, XML, and HTML, with CSV import and JSON-to-CSV output. Streaming validation can handle large JSON without loading the full document into memory; streaming schema validation through -jsv requires a JSONBuddy Large Data license. The Windows CLI supports repeatable checks in scripts and CI, while the published Core API v1 supports formatting, minifying, JSON Patch, schema validation, and documentation. ValBuddy CLI performs file operations locally on Windows, though selected content or diagnostics sent to an AI agent may reach its model provider.
