Hi There,

It’s been a while since I last posted here. Today I have released an update of my RefTreeAnalyser utility.

The tool now allows you to add a Table Of Contents to your workbook which contains lists of all sheets, all charts and all Pivottables:

In addition I have added a Feedback button to enable my users to send their complaints -I mean compliments- directly to me! So as of now, if you have ideas for improvements or suggestions for additions or a bug to report, use that feedback button!

Be safe!

Combinations, Combinations. A challenge

In case you’re bored stiff during your holiday, here’s a nice Excel challenge for you all.

In my newsletter for May 2019 I showed you a trick to get all possible combinations of two lists. This time I have a related problem. Suppose I have 10 ballot tickets. My job is to draw 5 random tickets from that set of 10 repeatedly until I have drawn all possible combinations:

The challenge I would like to give you all:
Please use any technique in Excel to list all possible unique combinations of ticket numbers drawn this way. Note that the order in which the tickets are drawn makes no difference and that each number can only be drawn once per set of 5. This means that a draw of (1, 2, 3, 4, 5) is considered the same as (5, 4, 3, 2, 1) or (2, 1, 3, 4, 5).

What’s in it for you?

The 5 best submissions will receive:

Send your solutions to info@jkp-ads.com using this subject line: “JKPADS Combinations Challenge”
