专业级 JSON 智能提取、格式化、校验与语义对比工具。“只要像 JSON 的字符串，通通都能一键解析！”

✨ 核心特性

• 右键选中文本即刻格式化：在 VS Code 编辑器中选中任何代码或日志文本，右键选择 easyJSON: 格式化/提取选中文本 即可自动提取清洗并格式化。
• 100+ 种非标字符串智能提取：无需手动寻找 JSON 头尾或人工反转义，自动将各种语言特有的打印字符串转化为标准 JSON。
• 4 大结构化视图：树形视图、代码高亮视图、脑图拓扑图谱、Excel 式表格视图。
• 语义级 Diff 差异对比：智能忽略 Key 排序不同与缩进差异，精准比对 JSON 值的字段增删与类型变更。
• 100% 本地内存解析：所有解析在本地完成，无网络请求，确保敏感日志与数据绝对安全。

5 大典型提取转换案例 (Examples)

1. Java Lombok toString() 智能转换

• 原始输入 (Raw String):

  User(id=1001, name=Alice, roles=[admin, dev], meta=Meta(dept=R&D, active=true))
  

• 提取后 Standard JSON:

  {
    "id": 1001,
    "name": "Alice",
    "roles": ["admin", "dev"],
    "meta": {
      "dept": "R&D",
      "active": true
    }
  }
  

2. Python dict / repr 混杂字符串转换

• 原始输入 (Raw String):

  {'status': 'ok', 'code': 200, 'items': [{'id': 1, 'flag': True}, {'id': 2, 'flag': False}], 'data': None}
  

• 提取后 Standard JSON:

  {
    "status": "ok",
    "code": 200,
    "items": [
      { "id": 1, "flag": true },
      { "id": 2, "flag": false }
    ],
    "data": null
  }
  

3. 多重转义 JSON 字符串自动反转义

• 原始输入 (Raw String):

  "{\"code\":0,\"msg\":\"success\",\"data\":{\"order_id\":\"ORD-20260730\",\"total\":99.50}}"
  

• 提取后 Standard JSON:

  {
    "code": 0,
    "msg": "success",
    "data": {
      "order_id": "ORD-20260730",
      "total": 99.5
    }
  }
  

4. 宽松 JavaScript / TypeScript 对象字面量

• 原始输入 (Raw String):

  { id: 101, title: 'easyJSON', tags: ['tool', 'json'], isPublished: true, extra: undefined }
  

• 提取后 Standard JSON:

  {
    "id": 101,
    "title": "easyJSON",
    "tags": ["tool", "json"],
    "isPublished": true,
    "extra": null
  }
  

5. 混杂系统日志文本中精准剥离 JSON

• 原始输入 (Raw String):

  [2026-07-30 13:28:00.123] [INFO] [UserServiceImpl.java:88] Payload: {"userId":8899,"action":"login","ip":"192.168.1.1"} - Execution time 12ms
  

• 提取后 Standard JSON:

  {
    "userId": 8899,
    "action": "login",
    "ip": "192.168.1.1"
  }

easyJSON for VS Code

Professional JSON Extraction, Formatting, Validation & Semantic Diff Tool. "Any string that looks like JSON can be parsed with one click!"

✨ Key Features

• Right-Click Instant Formatting: Select code or log text in the editor, right-click and choose easyJSON: Format / Extract Selected Text to parse and format automatically.
• Smart Extraction from 100+ Non-Standard Formats: No need to manually trim headers/footers or unescape strings. Works with Java Lombok toString(), Python dict/repr, JavaScript loose objects, escaped JSON strings, system logs, etc.
• 4 Interactive Structural Views: Tree View, Syntax Highlighted Code View, Topology Mind-map View, and Excel-style Grid Table View.
• Semantic Diff Comparison: Intelligently ignores key order and indentation differences to highlight true value modifications, key additions/deletions, and type changes.
• 100% Offline & Private: All data processing is done locally in memory without any external network requests.

5 Typical Transformation Examples

1. Java Lombok toString()

• Raw: User(id=1001, name=Alice, roles=[admin, dev], meta=Meta(dept=R&D, active=true))
• Parsed JSON: {"id":1001,"name":"Alice","roles":["admin","dev"],"meta":{"dept":"R&D","active":true}}

2. Python dict / repr

• Raw: {'status': 'ok', 'code': 200, 'items': [{'id': 1, 'flag': True}], 'data': None}
• Parsed JSON: {"status":"ok","code":200,"items":[{"id":1,"flag":true}],"data":null}

3. Escaped JSON String

• Raw: "{\"code\":0,\"msg\":\"success\",\"data\":{\"order_id\":\"ORD-20260730\"}}"
• Parsed JSON: {"code":0,"msg":"success","data":{"order_id":"ORD-20260730"}}

4. Loose JavaScript / TypeScript Object Literal

• Raw: { id: 101, title: 'easyJSON', tags: ['tool', 'json'], isPublished: true }
• Parsed JSON: {"id":101,"title":"easyJSON","tags":["tool","json"],"isPublished":true}

5. Embedded JSON in Mixed Log Text

• Raw: [2026-07-30 13:28:00] [INFO] UserService: Payload: {"userId":8899,"action":"login"} - 12ms
• Parsed JSON: {"userId":8899,"action":"login"}
