Excel/VBA实战：如何用股票代码列表快速构建你的自选股监控模板

Excel/VBA实战打造智能自选股监控模板全攻略1. 基础数据准备与清洗在开始构建自选股监控系统前我们需要先建立规范的股票代码数据库。打开Excel新建工作簿将股票代码和股票名称分别输入A1和B1单元格作为标题行。数据导入的三种高效方法手动输入法适用于少量数据直接在A2:B500区域逐行输入代码和名称使用数据验证防止重复输入 设置数据验证 With Range(A2:A500).Validation .Add Type:xlValidateCustom, Formula1:COUNTIF($A$2:$A$500,A2)1 .ErrorMessage 该代码已存在 End WithAPI获取法实时更新使用WEBSERVICE函数调用公开接口WEBSERVICE(http://hq.sinajs.cn/listsh601318)配合FILTERXML解析返回的XML数据VBA爬虫法批量获取Sub GetStockData() Dim http As Object, html As Object Set http CreateObject(MSXML2.XMLHTTP) http.Open GET, http://quote.eastmoney.com/stocklist.html, False http.send Set html CreateObject(HTMLFile) html.write http.responseText 解析HTML获取股票数据...
