Hello,

I have been reading everything I can and have not come up with the
solution and I am green to excel. Please assist me with this.

I have a list of 137 cells in A1:A137, each cell has data and none of
the cells are duplicates.

I want to randomly combine 10 of the cells together into B1:B137
separating each piece of data by a comma and repeat down the column so
that I have 137 cells with combined data.

Hope that makes sense?

Any help would be fantastic.

Thanks,

Louise

Louise,

Here is one formula that should work:

=INDEX($A$1:$A$137,RAND()*10)&","&INDEX($A$1:$A$13 7,RAND()*10)&","&INDEX($A$1:$A$137,RAND()*10)&","& INDEX($A$1:$A$137,RAND()*10)&","&INDEX($A$1:$A$137 ,RAND()*10)&","&INDEX($A$1:$A$137,RAND()*10)&","&I NDEX($A$1:$A$137,RAND()*10)&","&INDEX($A$1:$A$137, RAND()*10)&","&INDEX($A$1:$A$137,RAND()*10)&","&IN DEX($A$1:$A$137,RAND()*10)

Place this in B1 and copy down.

The Rand() function will return a random number and it will change whenever
the sheet recalculates. You can preserve the numbers once they are created by
copying the values in column B and then Paste Special: Values over the top.

Hope that helps.

Oops,

Sorry Louise, posted too quick.

In that formula, please change the " *10 " after the Rand() function to "
*137 ".

Please leave out the quotation marks. So the formula should read:

=INDEX($A$1:$A$137,RAND()*137)&","&INDEX($A$1:$A$1 37,RAND()*137)&","&INDEX($A$1:$A$137,RAND()*137)&" ,"&INDEX($A$1:$A$137,RAND()*137)&","&INDEX($A$1:$A $137,RAND()*137)&","&INDEX($A$1:$A$137,RAND()*137) &","&INDEX($A$1:$A$137,RAND()*137)&","&INDEX($A$1: $A$137,RAND()*137)&","&INDEX($A$1:$A$137,RAND()*13 7)&","&INDEX($A$1:$A$137,RAND()*137)

Hope THAT works.

I've put together a user defined function for you which I hope does
what you want (please let me know directly if it doesn't).

Please look at the attachment. You'll find the code for the UDF on the
module1 sheet.

Louise,

These formulas have the possibility of listing the same cell twice. That is,
it may duplicate a cell entry in column B.

In the UDF, I allowed for this and you should only get unique values.

That was exactly what I was looking for. I knew I would never figure it
out. Thanks so much.

Wow, haven't tried it yet...but I appreciate the responses. This will
be a piece that I will use over and over.

I will let you know if I have any issues.

Thanks so much,

Louise

For completeness sake, if anyone is following up, here is a formula method
modified from a Peo post back in 2002:

Insert a new column B. Type the Rand() function and copy down.

In C1 type the formula:

=INDEX($A$1:$A$136,MATCH(SMALL($B$1:$B$136,1),$B$1 :$B$136,0))&","&INDEX($A$1:$A$136,MATCH(SMALL($B$1 :$B$136,2),$B$1:$B$136,0))&","&INDEX($A$1:$A$136,M ATCH(SMALL($B$1:$B$136,3),$B$1:$B$136,0))&","&INDE X($A$1:$A$136,MATCH(SMALL($B$1:$B$136,4),$B$1:$B$1 36,0))&","&INDEX($A$1:$A$136,MATCH(SMALL($B$1:$B$1 36,5),$B$1:$B$136,0))&","&INDEX($A$1:$A$136,MATCH( SMALL($B$1:$B$136,6),$B$1:$B$136,0))&","&INDEX($A$ 1:$A$136,MATCH(SMALL($B$1:$B$136,7),$B$1:$B$136,0) )&","&INDEX($A$1:$A$136,MATCH(SMALL($B$1:$B$136,8) ,$B$1:$B$136,0))&","&INDEX($A$1:$A$136,MATCH(SMALL ($B$1:$B$136,9),$B$1:$B$136,0))&","&INDEX($A$1:$A$ 136,MATCH(SMALL($B$1:$B$136,10),$B$1:$B$136,0))

Copy C1, Paste Special:Values in each cell down to C137.

Third time's a charm...

Rand()*137 should be Rand()*137+1
