"Randomising" "number"
I have a worksheet, cells, b1, b2 and b3 of which each contains a 10-digit
hexadecimal number. In another cell, I have the following formula: =mid(b1&b2&b3,3,26) I have two questions about the above formula. First, how may I change it so that the three 10-digit numbers will not always be combined in the order b1, b2, b3, but will be combined in "random" order? Secondly, how may I change it so that the 30-digit number thus produced is reduced to 26 by choosing "randomly" whether to begin the 26-digit number at the 1st number of the 30 or a subsequent one? |

For your first question...
C1, copied down to C3: =RAND() Then, try the following... =MID(INDEX(B1:B3,MATCH(SMALL(C1:C3,1),C1:C3,0))&IN DEX(B1:B3,MATCH(SMALL(C 1:C3,2),C1:C3,0))&INDEX(B1:B3,MATCH(SMALL(C1:C3,3) ,C1:C3,0)),3,26) For your second question... =MID(INDEX(B1:B3,MATCH(SMALL(C1:C3,1),C1:C3,0))&IN DEX(B1:B3,MATCH(SMALL(C 1:C3,2),C1:C3,0))&INDEX(B1:B3,MATCH(SMALL(C1:C3,3) ,C1:C3,0)),RANDBETWEEN( 1,3),26) ....which requires that you enable the Analysis ToolPak add-in (Tools Add-ins check Analysis ToolPak) Hit the F9 key for a new combination of random numbers (actually, I'm not sure if it's the F9 key for the Windows version of Excel...I'm using the Mac version). Hope this helps! In article , "Leslie" wrote: I have a worksheet, cells, b1, b2 and b3 of which each contains a 10-digit hexadecimal number.

one way:
=MID(B1&B2&B3&B1&B3&B2&B2&B3&B1&B2&B1&B3&B3&B2&B1& B3&B1&B2, 30*INT(RAND()*6)+INT(RAND()*5)+1,26) In article , "Leslie" wrote: I have a worksheet, cells, b1, b2 and b3 of which each contains a 10-digit hexadecimal number.

Thank you to both Domenic and JE McGimpsey for your replies to my queries.
I'm in the process of trying your suggestions.
