Question

我是Google脚本的新手，我想在容器绑定的Google文档中创建一个脚本，该文档通过选项菜单转换为PDF格式的Google文档。问题是，如果我修改文档，它将创建在我的文件夹中具有相同名称的同一文件，所以如果文件存在，我想覆盖它（更新更新），如你所见，我试图通过不同的版本调用，我被阻止了很长一段时间考虑^^。如果你有同样的想法，我会很开心！非常感谢你。 :)

      file.getParents().next().removeFile(file);
      DriveApp.getFolderById(targetFolderId).addFile(file);
    }
