这可能在某处，我错过了，请告诉我。
运行我的宏后，我得到运行时错误7内存不足。经过调试，它就在这一行：
cell.Offset(0, 6).Value = Sheets("MakeRing_Maths").Range("N1").Value
该代码旨在运行具有经度和纬度的机场列表，创建将被解释为圆圈的线段，并转换为.KML（由Google地球专业版读取）。
以下是代码的其余部分 - 如何清理这样的内容以避免内存泄漏？
所有答案都赞赏，或指向其他帖子。我知道这很多，所以也欢迎一般的建议！谢谢！

非常感谢您的回答，我找到了解决方案！
原来一个简单的解决办法是截断一些数字，因为它们非常大（15个十进制数字），现在它就像一个魅力一样。
感谢您的时间！

始终要在代码中添加Option Explicit并明确声明变量。您可以按照以下步骤进行配置，以便编辑器自动添加此行。通过这种方式，您可以了解并能够管理变量，处理与其内存分配相关的数据类型。

湾检查需要变量声明。
对于VBA编译器而言，通过更多表达错误消息（例如，值太大）而不是普通的旧一般内存不足，这将是非常好的像这样。无论如何，以下是解释导致此错误的可能原因的链接。
您打开了太多应用程序，文档或源文件。关 任何不必要的应用程序，文档或源文件 开。
您的模块或程序太大。
将大型模块或程序分解为较小的模块或程序。这不会节省内存，但可以防止达到64K段边界。
您正在以标准模式运行Microsoft Windows。以增强模式重新启动Microsoft Windows。
您正在以增强模式运行Microsoft Windows，但虚拟内存已用完。通过释放一些磁盘来增加虚拟内存 空间，或至少确保有一些空间可用。
您正在运行终止和驻留程序。消除终止和驻留程序。
您加载了许多设备驱动程序。消除不必要的设备驱动程序。
Publicvariables
的空间不足减少公共变量的数量。
