如何在电子表格中将数字自动转化为大写的元角分？

=SUBSTITUTE(SUBSTITUTE(IF(A2<0,"负","")&TEXT(TRUNC(ABS(ROUND(A2,2))),"[DBNum2]")&"元"&IF(ISERR(FIND(".",ROUND(A2,2))),"",TEXT(RIGHT(TRUNC(ROUND(A2,2)*10)),"[DBNum2]"))&IF(ISERR(FIND(".0",TEXT(A2,"0.00"))),"角","")&IF(LEFT(RIGHT(ROUND(A2,2),3))=".",TEXT(RIGHT(ROUND(A2,2)),"[DBNum2]")&"分",IF(ROUND(A2,2)=0,"","整")),"零元零",""),"零元","零")
A2为数字所在单元格！

这公式是当出现负值是大写前面写“负”，如果想改为无效数值的话，公式需要修改为：
=IF(ROUND(A2,2)<0,"无效数值",IF(ROUND(A2,2)=0,"零",IF(ROUND(A2,2)<1,"",TEXT(INT(ROUND(A2,2)),"[dbnum2]")&"元")&IF(INT(ROUND(A2,2)*10)-INT(ROUND(A2,2))*10=0,IF(INT(ROUND(A2,2))*(INT(ROUND(A2,2)*100)-INT(ROUND(A2,2)*10)*10)=0,"","零"),TEXT(INT(ROUND(A2,2)*10)-INT(ROUND(A2,2))*10,"[dbnum2]")&"角")&IF((I
