<h4>💡 使用说明</h4>
<ul>
<li><strong>格式化</strong>：美化 JSON，使其易于阅读</li>
<li><strong>压缩</strong>：移除空格和换行，减小文件大小</li>
<li><strong>验证</strong>：检查 JSON 格式是否正确</li>
<li><strong>树形视图</strong>：可折叠的树形结构，点击 ▶/▼ 展开/折叠</li>
<li><strong>快速复制</strong>：鼠标悬停在树形节点上，点击 📋 复制该值</li>
<li><strong>快捷键</strong>：Ctrl+Enter 格式化，Ctrl+Shift+C 压缩</li>
</ul>
</div>
<div class="info-box warning">
<h4>⚠️ 常见错误</h4>
<ul>
<li><strong>缺少引号</strong>：键名必须用双引号包裹，如 "name"</li>
<li><strong>多余逗号</strong>：数组或对象最后一项后不能有逗号</li>
<li><strong>单引号</strong>：JSON 标准只支持双引号，不支持单引号</li>
<li><strong>注释</strong>：标准 JSON 不支持注释</li>
<li><strong>特殊字符</strong>：需要转义，如 \n \t \"</li>
