Question

假设单元格A5中包含以下公式：=SUM(A1:A5)

我想在此公式中使用VBA add 1来使其成为=SUM(A1:A5) + 1

我尝试了Range("A5") = Range("A5") + 1，但这只是将其改为硬编码而不是公式+ 1.我该如何解决这个问题？

感谢您的帮助！

Answer 1

这样的事情包括对公式存在的测试

If Range("A5").HasFormula Then Range("A5").Formula = Range("A5").Formula & "+1"

更新：要在大量选定的单元格上快速执行此操作，只会自动更新您应使用的公式variant arrays

更改后缀

的strAdd = "+1"

Answer 2

Range("A5").Formula = Range("A5").Formula & "+1"
