@Vegard，我希望你不介意我在你之后发布答案，但我一直在看这篇文章的扩展，我觉得其中有很多值得其他人学习的地方。
@&A65726F，我的某些回答可能看起来有点鲁棒，容我们说吧，所以通过橄榄枝，我在下面发布了一些代码，可以帮助您解决这个问题。
好的，所以...
- 我想知道您是否对项目的架构考虑得足够多。就目前而言，工作表数据需要进行大量验证，并且输入错误的范围很大，可能会弄乱您的代码。例如，依靠正确键入和正确大小写的“更改调制解调器”，以及正确格式和正确排序的日期，要求非常高。如果数据是从数据库导入的，那么 Excel VBA 是处理数据的最合适的地方吗？如果没有，那么如果您可以将其中一些字段转换为索引值（例如“更改调制解调器”= 0 等），那么您的生活会简单得多。在我看来，使用此电子表格通知设计他们公司的客户服务战略。
- 尝试在 VBA 中使用工作表函数来执行此任务会使代码相当笨拙，尤其是在第 1 点数据不可靠的情况下。如果可能，从工作表中读取数据，在 VBA 中运行适当的算法，然后将结果写回工作表。下面的示例绝不是最有效的示例，但为了让您了解一下，我已经从工作表中读取了数据，然后按
Collection 中的 ServiceNumber 将其分组。如果我要花时间在这项任务上，我可能也会把它放入日期的子组中。
- Stackoverflow：如果你能在表达你的问题之前非常准确地表达你的想法，那真的很有帮助。您可以从 'to and fro' cmets 字符串中看到，您的问题中没有足够的信息。如果是这种情况，请仔细阅读人们的 cmets 并返回并编辑您的问题。 Vegard 已多次要求您完善您的标准，但您仍然没有这样做。他还要求你仔细阅读他的代码并确保你理解它，但你只是继续不停地回复他。这里的每个人都想提供帮助，许多人都是各自领域的专家；如果他们说他们需要更多信息或需要做其他事情，那么听取他们的意见确实是明智的。 Stackoverflow 不是来为您编写代码的，而是来帮助指导您并克服障碍的。
下面是一些将开始攻击您的问题的代码。我已将其分解为小的模块化块，以便您可以查看每个部分的功能，并且可以随时扩展它们，例如有一个单独的数据验证例程。我不打算为你写你的项目，所以请自己花一些时间来完成它。这个想法是您在完善标准和扩展数据验证时自己添加。将此代码粘贴到Module：
