A typed model, queried edge cases, and a small change review that separates schema drift from implementation work.
依任務快速篩選工具，一鍵進入更合適的處理流程。
工作流程
將代表性 JSON 轉成 TypeScript，並在實作前檢查契約變化。
Use this path when a backend response, webhook sample, or configuration payload is about to become a frontend or SDK contract.
A typed model, queried edge cases, and a small change review that separates schema drift from implementation work.
這些工作流程頁面不會處理、收集或儲存工具輸入。請直接使用連結工具，並在處理敏感資料前查看其信任標籤。
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 轉 TypeScriptQuery nested values and optional branches so the implementation does not rely on one happy path sample.
JSONPath 遊樂場Diff old and new payloads or generated types before updating consumers.
JSON 差異比對即時格式化、驗證和壓縮 JSON 資料。
在瀏覽器本機從 JSON 產生起始 Schema，並執行基礎支援的 Schema 檢查。
從 JSON 自動產生 TypeScript 介面。
使用 JSONPath 運算式互動式查詢 JSON 資料。
在本機將 JSON、YAML 與 XML 顯示為樹狀結構、關係邊與結構統計。
比對兩個 JSON 檔案並視覺化差異。
本機比較兩份 OpenAPI 或 Swagger 規格，標記端點、參數、回應、安全與破壞性風險變更。
格式化 GraphQL 查詢、驗證變數 JSON，並檢查貼上的 introspection 資料，無需連線伺服器。
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.
