我们些活动，需要分给同学一些密码，用来限定参加活动的次数和人员。但是人数太多，我们要自己选择不重复的密码实在困难，所以想问下有没有哪些软件能够帮到我们的？
例如我们的每个密码都是前面3位为26个字母中任意三个，后面5位是0-9中任5个，他们出现次数不限。最好有可以多个密码一次选出的功能。

用excel的随机函数就可以实现了啊。追问
请详细说明下步骤可以吗？
追答前三列输入=CHOOSE(MOD(INT(RAND()*1000),3)+1,"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z")，后5列输入=INT(MOD(RAND()*10,10))，然后往下拉就可以了。
