在Excel中将金额转换为中文大写，可以使用以下公式：
使用自定义函数
按下 `Alt + F11` 打开VBA编辑器。
插入一个新模块，并输入以下代码：
```vba
Function ConvertToChineseNum(ByVal num As Double) As String
Dim ChineseNum As Variant
ChineseNum = Array("零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖")
Dim ChineseUnit As Variant
ChineseUnit = Array("", "拾", "佰", "仟", "万", "亿")
Dim str As String
Dim i As Integer
Dim j As Integer
Dim k As Integer
Dim n As Integer
Dim m As Integer
Dim temp As String
Dim flag As Boolean
str = Format(num, "0.00")
str = Replace(str, ".", "")
n = Len(str)
For i = 1 To n
If Mid(str, i, 1) <> "0" Then
If flag = True Then
str = Left(str, i - 1) & ChineseNum(Mid(str, i, 1))
Else
str = str & ChineseNum(Mid(str, i, 1))
End If
flag = False
Else
If Mid(str, i, 1) = "0" And i <> n Then
str = str & ChineseNum(Mid(str, i, 1))
End If
End If
Next i
For i = 1 To UBound(ChineseUnit)
If Right(str, i) = "" Then
Exit For
Else
str = Left(str, Len(str) - i + 1) & ChineseUnit(i)
End If
Next i
ConvertToChineseNum = str
End Function
```
保存并关闭VBA编辑器。
在Excel中，选择需要转换的金额单元格，输入公式 `=ConvertToChineseNum（A1）`，然后按回车键即可看到转换后的中文大写金额。
使用Excel自带的公式
在需要转换的金额单元格中输入以下公式：
```excel
=TEXT(INT(--RMB(C34)), "[dbnum2]") & "元" & IF(OR((C34 - INT(C34)) = 0, (RMB(C34) - INT(C34)) = 1), "整", IF(LEFT(RIGHT(TEXT(RMB(C34), "[dbnum2]"), 3), 1) = ".", IF((RMB(C34) - INT(C34)) * 100 > 10, TEXT((RMB(C34) - INT(C34)) * 100, "[dbnum2]0角0分"), TEXT((RMB(C34) - INT(C34)) * 100, "[dbnum2]00分")), TEXT((RMB(C34) - INT(C34)) * 10, "[dbnum2]0角整")))
```
将公式中的 `C34` 替换为需要转换的金额所在的单元格地址。
这些方法可以帮助你在Excel中快速将金额转换为中文大写，选择适合你的方法进行尝试即可。
