excel - 将多个 CSV 文件从 Internet 导入到 Excel 中

Question

我使用此代码检索大约 40 个股票的历史股票价格。我在这里找到了http://www.mathfinance.cn/download-multiple-stock-quotes-from-yahoo-finance

在弹出运行时错误“1004”之前，它会下载大约一半的符号。 “无法打开 http://table.finance.yahoo.com/table.csv?s=Tickersymbol&a=11&b=21&c=1998 网站报告找不到您请求的项目 (HTTP/1.0 404)

我可以更改代码以使此错误不会发生吗？代码如下

编辑:下面的代码修复了您报告的问题，但很快就会耗尽内存。我创建了另一个答案，我认为它更好、更可靠

服务器似乎无法识别您的查询。如果遇到此类错误，您可以添加一些错误检查以继续。

您可能想要删除该工作表，而不是在其中添加错误消息，或者发送一个 MsgBox...
