在Excel中将数字转换为财务大写可以通过使用内置的函数或自定义的VBA代码来实现。
首先，Excel内置了一些函数可以用来将数字转换为大写汉字。比如，可以使用TEXT函数和自定义的数字格式来实现。具体步骤如下：
1. 在需要转换数字的单元格旁边添加一个辅助列；
2. 在辅助列中使用以下公式：=TEXT(A1,"[DBNum2]")（假设A1是需要转换的数字单元格）；
3. 然后将公式结果复制为值，即可得到财务大写的数字。
但是，这种方法只能将数字转换为简单的大写汉字，对于财务票据中需要的复杂格式，比如“壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、佰、仟、万、亿”等，无法完全满足需求。
此时，可以通过自定义VBA代码来实现更加复杂的财务大写转换。具体步骤如下：
1. 打开Visual Basic for Applications（VBA）编辑器；
2. 插入一个新的模块，将以下代码复制粘贴进去：

Dim MyNumber As String
Dim DecimalPlace As String
Dim Count As Integer

NumToChinese = ""
Exit Function
End If
DecimalPlace = InStr(MyNumber, ".")
DecimalSeparator = ""
If DecimalPlace > 0 Then
DecimalSeparator = " Point "
DecimalValue = GetTens(Left(Mid(MyNumber, DecimalPlace + 1) & "00", 2))

If Temp <> "" Then DecimalSeparator = " Thousand " & DecimalSeparator

End If
NumToChinese = Temp & Place(Count) & NumToChinese
Count = Count + 1

If Mid(MyNumber, 2, 1) <> "0" Then Result = Result & GetTens(Mid(MyNumber, 2))
If Mid(MyNumber, 3, 1) <> "0" Then Result = Result & GetDigit(Mid(MyNumber, 3))
GetHundreds = Result
End Function
Function GetTens(TensText As String) As String
Dim Result As String
