Validate JSON reliably
Catch syntax errors and JSON Schema violations with precise diagnostics before bad data reaches production.
Explore JSON validationJSONBuddy
Build, validate, and automate JSON with confidence
Validate data, build reliable schemas, test contracts, format and transform JSON, or work with very large files—all with focused tools for interactive and automated workflows.
Process files locally with the Windows CLI, give an AI agent the diagnostics it needs, or use the desktop application to edit, inspect, and debug the result.
- Edit JSON in text and grid views
- Validate JSON and modern JSON Schema
- Automate repeatable checks with CLI and CI
Flexible access
Choose where to run it
Run files locally from the Windows desktop or CLI, connect repeatable checks to an agent or CI job, or choose a documented remote operation.
Choose the outcome
One JSON platform, built around the outcome you need
JSONBuddy keeps established editor, validator, schema, grid, formatter, conversion, download, CLI and large-data workflows visible while organizing them around the result you need.
Build and govern schemas
Create, resolve, analyze, test and document JSON Schemas with a dedicated development environment.
Explore schema workflowsFormat and transform JSON
Pretty-print, minify, patch and convert JSON, CSV and XML without erasing the distinct intent of each tool.
Explore formattingAutomate quality checks
Run validators from the Windows command line, reuse the same invocation in CI, and gate the workflow on the exit status.
Explore CLI and CIWork with large JSON
Open, inspect, validate, format and convert data that is too large for ordinary editors.
Explore large-data workflowsUnderstand and share schemas
Generate readable JSON Schema documentation for teams, reviewers and integrators.
Explore schema documentationLocal tools for agents and automation
Reduce setup work and unnecessary model context
Ready-to-run ValBuddy commands let developers, AI coding agents, and CI jobs apply the same JSON Schema check without repeatedly choosing dependencies or generating validation glue code. The CLI reads the files in the Windows environment and returns status and diagnostics; the agent can interpret those results without receiving the entire document.
An agent may still send selected content or diagnostics to its model provider. Schema references can also require network access when they resolve to remote resources.
- Desktop: interactive JSON and JSON Schema editing on Windows.
- CLI / CI: repeatable validation and conversion in automation.
- Web API: use the public service contract for supported remote operations.
- AI agents: use AI-agent workflows; ValBuddy for Codex stays distinct.
- Browser tools: focused in-browser workflows remain intentionally unlinked.
A dependable Windows JSON editor
Keep the familiar editor workflow—add clearer paths to every capability
Desktop users can edit JSON in text and grid views, validate against modern JSON Schema drafts, format documents, convert data, and inspect actionable diagnostics in one application.
