什么是 JSON 查看器？
JSON（JavaScript Object Notation）是一种轻量级的数据交换格式，广泛用于前后端数据通信和配置文件。JSON 查看器可以帮助开发者直观地浏览、检查和调试 JSON 数据。
本工具支持以下功能：
- 格式化：将压缩的 JSON 字符串按层级缩进美化，便于阅读和调试
- 压缩：去除多余空格和换行，减小数据体积
- 验证：自动检测 JSON 语法错误，精确定位问题位置
- 树视图：以可交互的树形结构展示 JSON，支持逐级折叠/展开对象和数组
- 原始视图：以纯文本格式查看格式化后的 JSON
- 全部展开/折叠：一键展开或折叠所有对象和数组节点
- 字符串去转义：自动将 JSON 字符串中的转义序列（如 \n、\t、\uXXXX）还原为原始字符，方便查看中文和特殊字符
- 复制：一键复制处理结果到剪贴板
所有数据仅在浏览器本地处理，不会上传到服务器，保障数据安全。
What is a JSON Viewer?
JSON (JavaScript Object Notation) is a lightweight data interchange format widely used for frontend-backend communication and configuration files. A JSON viewer helps developers intuitively browse, inspect, and debug JSON data.
This tool supports:
- Format — Pretty-print compressed JSON with proper indentation for readability and debugging
- Minify — Remove unnecessary whitespace and line breaks to reduce data size
- Validate — Automatically detect JSON syntax errors and pinpoint problem locations
- Tree View — Display JSON as an interactive tree structure, with per-node collapse/expand for objects and arrays
- Raw View — View formatted JSON as plain text
- Expand/Collapse All — One-click expand or collapse all object and array nodes
- Unescape Strings — Automatically convert escape sequences (e.g., \n, \t, \uXXXX) in JSON strings back to their original characters for easier reading of CJK text and special characters
- Copy — One-click copy of the result to your clipboard
