在excel里生成不重复的8位随机码包(含字母数字)
在一个单元格里输入
=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)))),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)))))
当然如果需要更多就在最后一个括号钱加,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))))
加几个就是几位的
