把代表性 JSON 转成 TypeScript，并在实现前检查契约变化。
Use this path when a backend response, webhook sample, or configuration payload is about to become a frontend or SDK contract.

Use a payload with real structure but no private data so optional fields and nested arrays are visible.
JSON 格式化工具Create the first contract and inspect whether nulls, arrays, and numeric IDs are represented correctly.
JSON 转 TypeScriptQuery nested values and optional branches so the implementation does not rely on one happy path sample.
JSONPath 游乐场Diff old and new payloads or generated types before updating consumers.
JSON 差异对比即时格式化、验证和压缩 JSON 数据。
在浏览器本地从 JSON 生成起始 Schema，并运行基础受支持的 Schema 检查。
从 JSON 自动生成 TypeScript 接口。
使用 JSONPath 表达式交互式查询 JSON 数据。
在本地将 JSON、YAML 和 XML 展示为树形结构、关系边和结构统计。
对比两个 JSON 文件并可视化差异。
本地比较两个 OpenAPI 或 Swagger 规格，标记端点、参数、响应、安全和破坏性风险变化。
格式化 GraphQL 查询、校验变量 JSON，并检查粘贴的 introspection 数据，无需连接服务器。
Review schema coverage, required fields, and compatibility before implementation.
Know which syntax belongs in strict JSON contracts and which does not.
A checklist for validating request payloads before replaying or sharing them.
No. It improves developer ergonomics, but runtime validation is still needed at trust boundaries.
Use at least one normal case and one edge case with optional or nullable fields before treating the contract as stable.
Use JSONPath when nested arrays or deeply nested fields drive UI behavior or API compatibility decisions.
