怎样用excel表格生成4位随机的编码，谢谢

Posted 2023-04-05

如下图：在B列依次列出0-9，A-Z共36个字符，在A列分别赋予序号1-36，在D1输入公式=VLOOKUP(RANDBETWEEN(1,36),A2:B37,2,0)&VLOOKUP(RANDBETWEEN(1,36),A2:B37,2,0)&VLOOKUP(RANDBETWEEN(1,36),A2:B37,2,0)&VLOOKUP(RANDBETWEEN(1,36),A2:B37,2,0)。按F9刷新即可以出一个随机的4位编码。

公式看起来很长，实际也就是用&把4个VLOOKUP(RANDBETWEEN(1,36),A2:B37,2,0)连接起来。

参考技术A =CONCATENATE(IF(INT(RAND()*2)=0,CHAR(INT(RAND()*9+48)),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*25+65)),CHAR(INT(RAND()*25+97)))),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*9+48)),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*25+65)),CHAR(INT(RAND()*25+97)))),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*9+48)),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*25+65)),CHAR(INT(RAND()*25+97)))),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*9+48)),IF(INT(RAND()*2)=0,CHAR(INT(RAND()*25+65)),CHAR(INT(RAND()*25+97)))))

在excel中怎样生成随机的4位字母数字组合，谢谢

产生大写字母与数字的组合
=CHAR(RANDBETWEEN(65,90))
=IF(RAND()<0.5,CHAR(RANDBETWEEN(48,57)),CHAR(RANDBETWEEN(65,90))) &IF(RAND()<0.5,CHAR(RANDBETWEEN(48,57)),CHAR(RANDBETWEEN(65,90)))&IF(RAND()<0.5,CHAR(RANDBETWEEN(48,57)),CHAR(RANDBETWEEN(65,90)))&IF(RAND()<0.5,CHAR(RANDBETWEEN(48,57)),CHAR(RANDBETWEEN(65,90))) 参考技术A =if(randbetween(0,1),randbetween(0,9),char(randbetween(65,90)))&if(randbetween(0,1),randbetween(0,9),char(randbetween(65,90)))&if(randbetween(0,1),randbetween(0,9),char(randbetween(65,90)))&if(randbetween(0,1),randbetween(0,9),char(randbetween(65,90)))
