excel - 如何使用 VBA 在 Excel 单元格中输入大字符串？

Question

我正在使用 Excel VBA。我有一个字符串想要写入单元格。我不确定实际的字符限制是什么，但是对于很长的字符，我会收到运行时错误。这是程序中断的行:

Cells(i, 7).Formula = region_opp_amount & ")"

此场景中的字符串“region_opp_amount”的长度为 1691。它基本上是一个大型 SUM 公式。以下是该字符串包含的内容(要求和的大单元格列表):“=sum(G2057,G2066,G2069,G2072,G2076,G2079,G2082,.....”

有什么办法可以克服这个限制吗？

这是创建此字符串的实际循环:

Do While i <= lastRow
    If Cells(i, 2).value <> "" Or i = lastRow Then
        If i <> lastRow Then
            region = Left(Cells(i, 2).value, InStr(Cells(i, 2).value, " - ") - 1)
            rep = Right(Cells(i, 2).value, Len(Cells(i, 2).value) - InStr(Cells(i, 2).value, " - ") - 2)
        Else
            region = ""
            rep = ""
            i = i + 1
        End If
        If rep <> last_rep And i <> 2 Then
            Rows(i).Insert
            With Rows(i)
                .ClearFormats
                .Font.Bold = True
                On Error Resume Next
                .Ungroup
                On Error GoTo 0
            End With
            lastRow = lastRow + 1
            Cells(i, 2).value = last_rep & " Subtotal:"
            Cells(i, 7).Formula = rep_opp_amount & ")"
            Cells(i, 9).Formula = replace(rep_opp_amount, "G", "I") & ")"
            Cells(i, 12).Formula = "=sum(L" & CStr(rep_start) & ":L" & CStr(i - 1) & ")"

            Cells(i, 14).Formula = "=sum(N" & CStr(rep_start) & ":N" & CStr(i - 1) & ")"

Answer 1

好的，这是一个例子。在这个例子中，我直接采用了问题中提到的字符串。

逻辑:

1. 拆分单元格地址并将其存储在数组中
2. 重新制作字符串，确保长度不超过 240(我使用了 230。我正在考虑像 XFD1048576 这样的单元格)
3. 达到该限制后，创建一个命名范围。我使用过诸如MyRange1、MyRange2、MyRange3...之类的名称。人们可以使用更短的名称，例如 Rng1,Rng2...
4. 重复步骤 2 和 3，直到创建所有命名范围。
5. 只需在公式中使用命名范围

因此这 6 个命名范围覆盖了大约 240 个单元格。
