runapi 项目无法实现导出后无损导入（不要求使用 openapi 格式，任何格式都可以）

Only export to doc documents, which are actually in html format, and some format data (such as json message body beautification options, environment variables) are lost; only support importing json files from postman and openapi, and some data is lost during import (such as schema field descriptions, environment variables).
