#json

Query and extract from JSON with JSONPath, server-side. Run any JSONPath expression — wildcards, recursive descent, array slices and filter expressions like [?(@.price>10)] — against a JSON document and get back the matched values, the normalized paths and JSON Pointers of every match, or just the first match. Filter expressions are evaluated in a safe sandbox with no access to globals, and inputs can be sent as a JSON POST body or a query parameter. Pure local compute with no third-party upstream, so responses are instant and the service is always available. Ideal for no-code and automation platforms, ETL and data pipelines, API integrations, testing and config extraction.

Convert, validate and tidy YAML through a fast, fully-local API. Turn YAML into JSON (including multi-document streams) or JSON into clean YAML with optional key sorting and custom indentation, validate a document and get the exact line and column of any syntax error with a context snippet, or reformat and normalize existing YAML. Inputs can be sent as a raw text/plain body, a JSON field or a query parameter; outputs are tidy JSON. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for DevOps and CI/CD, configuration and infrastructure-as-code tooling, no-code platforms, editors and data pipelines.

Validate JSON against JSON Schema, server-side. Check any data against a schema (Draft-07 or 2020-12) and get a clear pass/fail plus a detailed list of every error with its instance path, failing keyword and message; verify that a schema itself is well-formed; or infer a starter JSON Schema automatically from a sample document, complete with detected formats like email, URI and date. Built on the battle-tested Ajv engine with full format validation. Every endpoint accepts GET (JSON-encoded parameters) or a JSON POST body and runs entirely locally with no third-party upstream, so responses are instant and the service is always available. Ideal for API request/response validation, form and data-entry checks, ETL and data-quality pipelines, no-code platforms and contract testing.
