Excel自动转换数字大小写具体的操作步骤如下：
1. 启动excel。按“alt+f11”快捷键打开“visual basic编辑器”。
2. 在“visual basic编辑器”中，单击“插入”菜单栏中的“模块”命令，插入一个模块。双击左侧“工程”窗口中的“模块1”选项，在窗口右边展开“模块1（代码）”编辑窗口，然后输入如下代码:
function dx(q)
dim cur as long,yuan as long
dim jiao as integer,fen as integer
dim cnyuan as string, cnjiao as string, cnfen as string
if q = "" then
dx = 0
exit function
end if
cur = round(q * 100)
yuan = int(cur / 100)
jiao = int(cur / 10) - yuan * 10
fen = cur - yuan * 100 - jiao * 10
cnyuan = application.worksheetfunction.text(yuan, "[dbnum2]")
cnjiao = application.worksheetfunction.text(jiao, "[dbnum2]")
cnfen = application.worksheetfunction.text(fen, "[dbnum2]")
dx = cnyuan & "元" & "整"
d1 = cnyuan & "元"
if fen <> 0 and jiao <> 0 then
dx = d1 & cnjiao & "角" & cnfen & "分"
if yuan = 0 then
dx = cnjiao & "角" & cnfen & "分"
end if
end if
if fen = 0 and jiao <> 0 then
dx = d1 & cnjiao & "角" & "整"
if yuan = 0 then
dx = cnjiao & "角" & "整"
end if
end if
if fen <> 0 and jiao = 0 then
dx = d1 & cnjiao & cnfen & "分"
if yuan = 0 then
dx = cnfen & "分"
end if
end if
end function
输 入完成后，关闭“visual basic编辑器”返回工作表。现在，我们可测试一下这个函数。首先，在a1单元格中输入一个小写数字的金额，例如123456.78，然后，在a2单元 格中输入公式：=dx(a1)，确认后即可将a1所表示的小写数字金额转换为大写的数字金额，并在a2单元格中显示出来。怎么样，方便吧？
