在前后端开发或API调试中，常常需要在JSON对象和URL查询字符串（GET参数）之间进行转换。本工具可快速将JSON对象转换为标准的GET参数字符串，也能将GET参数字符串解析为格式化的JSON对象，解决手工拼接或解析易出错的痛点，提升接口对接效率。
key1=value1&key2=value2 的字符串；GET转JSON时输出格式化的JSON对象。示例：输入JSON {"name":"张三","age":25} 转换为GET参数 name=%E5%BC%A0%E4%B8%89&age=25；反向输入 name=%E5%BC%A0%E4%B8%89&age=25 得到JSON。
请确保输入的JSON格式合法，否则会提示错误。GET参数转换时，键值对以“&”分隔，键值用“=”连接。本工具仅处理字符串转换，不涉及网络请求，所有数据仅在浏览器本地处理，不会上传服务器，保障隐私安全。对于大量数据或批量转换，建议分批次处理以免页面卡顿。
在RESTful API设计中，查询参数经常需要结构化传递。使用本工具可快速验证GET参数结构。例如，传递筛选条件 filter[status]=active&filter[age][gte]=18 可被转换为嵌套JSON {"filter":{"status":"active","age":{"gte":"18"}}}。请留意不同后端框架对参数解析的差异，本工具采用通用的URLSearchParams解析规则。
