我想将以下这几个单元格的数字转换为一个整体的大写金额，该怎么设置呢？

A2=SUBSTITUTE(SUBSTITUTE(IF(-RMB(C2*1000000+D2*100000+E2*10000+F2*1000+G2*100+H2*10+I2*1+J2*0.1+K2*0.01),IF(C2*1000000+D2*100000+E2*10000+F2*1000+G2*100+H2*10+I2*1+J2*0.1+K2*0.01>0,,"负")&TEXT(INT(ABS(C2*1000000+D2*100000+E2*10000+F2*1000+G2*100+H2*10+I2*1+J2*0.1+K2*0.01)+0.5%),"[dbnum2]G/通用格式元;;")&TEXT(RIGHT(RMB(C2*1000000+D2*100000+E2*10000+F2*1000+G2*100+H2*10+I2*1+J2*0.1+K2*0.01,2),2),"[dbnum2]0角0分;;整"),),"零角",IF(C2*1000000+D2*100000+E2*10000+F2*1000+G2*100+H2*10+I2*1+J2*0.1+K2*0.01^2<1,,"零")),"零分","整")
