如何在Excel中创建GUID？

Question

我需要一个函数来向Excel中的单元格添加GUID.我在stackoverflow上找到了上一个问题,但它无效.它建议以下功能:

=CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8),"-",DEC2HEX(RANDBETWEEN(0,6553??5),4),"-
 ",DEC2HEX(RANDBETWEEN(16384,20479),4),"-",DEC2HEX(RANDBETWEEN(32768,49151??),4),"-
 ",DEC2HEX(RANDBETWEEN(0,65535),4),DEC2HEX(RANDBETWEEN(0,4294967295),8))

我一直无法使concatenate方法工作,所以尝试使用"&"图来连接.这似乎有效,但后来我在第二个DEX2HEX块上出现了一个莫名其妙的错误:DEC2HEX(RANDBETWEEN(0,6553 5),4).Excel公式评估员说这是无效的,但我似乎无法弄清楚为什么.有任何想法吗？

Answer 1

从Excel的现代版本开始,语法是逗号,而不是分号.我发布这个答案是为了方便他人,所以他们不必更换字符串 - 我们都懒惰......小时候......人类,对吗？

= CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8), " - ",DEC2HEX(RANDBETWEEN(0,42949),4), " - ",DEC2HEX(RANDBETWEEN(0,42949),4), " - " ,DEC2HEX(RANDBETWEEN(0,42949),4), " - ",DEC2HEX(RANDBETWEEN(0,4294967295),8),DEC2HEX(RANDBETWEEN(0,42949),4))

或者,如果你喜欢我不喜欢guid尖叫和喊叫你,我们可以像这样低调.

= LOWER(CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8), " - ",DEC2HEX(RANDBETWEEN(0,42949),4), " - ",DEC2HEX(RANDBETWEEN(0,42949),4)," - ",DEC2HEX(RANDBETWEEN(0,42949),4), " - ",DEC2HEX(RANDBETWEEN(0,4294967295),8),DEC2HEX(RANDBETWEEN(0,42949),4)))

Answer 2

=CONCATENATE(
    DEC2HEX(RANDBETWEEN(0;4294967295);8);"-";
    DEC2HEX(RANDBETWEEN(0;42949);4);"-";
    DEC2HEX(RANDBETWEEN(0;42949);4);"-";
    DEC2HEX(RANDBETWEEN(0;42949);4);"-";
    DEC2HEX(RANDBETWEEN(0;4294967295);8);
    DEC2HEX(RANDBETWEEN(0;42949);4)
)

Answer 3

我在v.2013 excel vba宏代码中使用以下函数

Public Function GetGUID() As String 
    GetGUID = Mid$(CreateObject("Scriptlet.TypeLib").GUID, 2, 36) 
End Function 

Answer 4

这根本不是功能问题.

我花了一些时间挖掘,但问题在于复制和粘贴.尝试复制此:RANDBETWEEN(0,6553??5)字符串,在原始问题中发布,然后将其粘贴到十六进制编辑器中,然后您将看到65535中实际上有两个空字符:

00000000  52 41 4E 44 42 45 54 57 45 45 4E 28 30 2C 36 35  RANDBETWEEN(0,65
00000010  35 33 00 00 35 29                                53?..?5)

Answer 5

=LOWER(
    CONCATENATE(
        DEC2HEX(RANDBETWEEN(0,POWER(16,8)),8), "-", 
        DEC2HEX(RANDBETWEEN(0,POWER(16,4)),4),"-","4", 
        DEC2HEX(RANDBETWEEN(0,POWER(16,3)),3),"-",
        DEC2HEX(RANDBETWEEN(8,11)),
        DEC2HEX(RANDBETWEEN(0,POWER(16,3)),3),"-",
        DEC2HEX(RANDBETWEEN(0,POWER(16,8)),8),
        DEC2HEX(RANDBETWEEN(0,POWER(16,4)),4)
    )
)
