做开发的人都知道，JSON 写起来顺手，但碰到老系统对接、政务平台或者企业级 ERP，对方往往只认 XML。两种格式各有地盘，强行手改既费时又容易出错。这个工具帮你把 JSON 直接转成规范的 XML，结构层级完整保留，属性和节点该怎么映射就怎么映射。不管是微信小程序的数据要导进传统后台，还是跨境电商的商品信息要对接海关申报系统，粘贴进来转一下就能用，省去反复调格式的麻烦。
- 微信小程序接口数据转换为企业 ERP 可识别的 XML 报文
- 跨境电商平台商品数据对接海关或物流系统的 XML 申报格式
- 手游服务端配置文件在 JSON 与 Unity/Cocos 引擎 XML 资源格式之间互转
大陆不少政务和金融系统仍以 XML Schema（XSD）作为数据交换标准，台湾的健保、电子发票平台同样依赖 XML 传输。转换时注意编码声明须为 UTF-8，否则提交后容易出现乱码被退件。
