one way is put an index 1 to 1000 in the previous column to the names
column . and then in some other column choose 20 random numbers between 1 and 1000 and choose the name correponding to these random numbers by using vlookup function. yorkshire exile <yorkshire wrote in message ...

Get my function UniqRandInt() from www.sulprobil.com,
select 20 cells and enter =UniqRandInt(1000) with CTRL+SHIFT+ENTER (array formula) to get 20 different numbers or =INDEX($A$1:$A$1000,UniqRandInt(1000)) as an array formula to get 20 different random names if these are in cells A1:A1000, for example. HTH, Bernd |

One way ..
Assuming the list of names is in A1:A1000 Put in say, E1: =RAND() Copy down to E1000 Put in B1: =INDEX(A:A,MATCH(SMALL(E:E,ROWS($A$1:A1)),E:E,0)) Copy down to B20* (since you want 20 names at random) B1:B20 will return a non-repeating randomized selection of 20 names from amongst the list in col A Press/tap F9 to recalc / re-generate a fresh selection Just freeze the results elsewhere with a copy paste special values ok *Copy down further as desired if you need more than 20 names, or all the way to B1000 to get a random mix of all 1000 names in col A -- Rgds Max xl 97 --- GMT+8, 1° 22' N 103° 45' E xdemechanik <atyahoo<dotcom ---- "yorkshire exile" <yorkshire wrote in message ...

Take a look at
http://www.mcgimpsey.com/excel/randomint.html You can use the RandInt function found there. Assume your names were in column A. Select, say, B1:B20 and array-enter (CTRL-SHIFT-ENTER or CMD-RETURN): =INDEX(A:A,RandInt(1,COUNTA(A:A))) In article , yorkshire exile <yorkshire wrote: I need to be able to choose 20 names at random from an existing database of over 1000 names |
