以下代码用于将 CSV 文件转换器转换为 excel 表格形式。
问题是当整个工作簿被保存(MACRO-ENABLED EXCEL FORM)时，问题就开始了。当工作簿是新的并且当我复制粘贴程序并运行它而不保存它时，程序运行良好，但在保存它以供以后使用后，程序将无法完成它的工作。我运行它时没有错误消息。它只是不做它所做的事情。

最佳答案
您的 sPath 值是双路径值，第一个路径是您的工作簿自身，第二个路径是 csv 路径.. sPath 变量应该是 sPath = strPath因为要尝试打开的文件只是 csv 文件。在保存工作簿之前，sPath 没问题，因为工作簿路径为空，sPath 的值只是 csv 路径，将工作簿保存到文件后，工作簿有路径文件。
所以只是edit sPath = ThisWorkbook.Path & strPath至sPath = strPath
