Last night I got an email from Joshua, one of our readers with the subject – Hard Excel problem. Hard?!?, at this stage of summer, the hard problems seem to be (in no particular order),
- Lack of good quality mangoes to eat
- Intense heat and humidity
- Lack of good quality mangoes to eat
Yes, I like mangoes.
Any how, back to Joshua’s email, So I got curious and read it. He is facing an interestingproblem.
I have a very difficult inquiry I am hoping you might be able to solve…
Is there a formula (i.e., without using VBA) that will look at another columns values and provide a new sequential number (i.e., reordered) when the value changes; however, keep the same sequential number for the duplicates?
Below is a table with two columns. […] I now need to rank order those cluster groups. Since cluster 12 appears first it would get a value of ‘1’ and all of the cluster 12’s should now be a ‘1’. Since cluster 4 appears next it would get a rank of 2, etc…
Well, it is an interesting problem for sure. But hard problem, it isn’t. For really hard problems, refer to my list above.
So how to generate the sequence numbers?
Logic: If a value is already listed, we fetch corresponding sequence number. Else, we generate a new sequence number.
Implementation: Simple, we use VLOOKUP.
Assuming the cluster values are in column B, from B4 onwards, in C4, write
=IFERROR(VLOOKUP(B4,$B$3:C3,2,FALSE), SUM(MAX($C$3:C3),1))
Let’s examine the formula.
VLOOKUP(B4,$B$3:C3,2,FALSE) portion: This one looks value in column B and tries to find corresponding sequence value in column C.
SUM(MAX($C$3:C3),1) portion: Gives us next sequence number
IFERROR(VLOOKUP(…), SUM(…)) portion: This does the magic of choosing either existing sequence number or generating a new one.

Hard problems are not new at Chandoo.org. We take lob vlookups and sumproducts regularly to crack them. Here are few examples:

@Chandoo:
One more useful trick.......
In a column you have no. of data in rows and need to copy in the next row from the previous row, no need to go for the previous rows but entering Alt + down arrow, you will get the list of data, (in asending order), entered in the previous rows...
This is another great tip. I use this all the time to make sense of some *very* long formulas. As soon as the formula is debugged I remove the break.
Great tip Chandoo!
I use this feature often and it has even gotten the, "how did you do that" response.
Thanks!
@Ketan: Alt+down arrow is an awesome tip. I never knew it and now I am using it everyday.
@Jorge, Tony: Agree... 🙂
[...] Day 1: Insert Line Breaks in a Cell [...]
how can we merge a two sheet.
excellent idea. Chandoo you are genious
Hi chandoo,
I have used ctrl+enter to break the cell. But I did not get the result.
Please tell me how can i break the cell in multiple lines.
Hi, Ranveer,
Its not Ctrl+enter to break the cell, use Alt+Enter to make it happen.
hi Chandoo....
how we can use Alt+Enter in multiple rows at the same time please reply hurry i have lot of work and have no time and i m stuck in this. 🙁
Alt+J worked once 🙁
So I found another more reliable way:
=SUBSTITUTE(A2,CHAR(13),"")
Where A2 is the cell that contains the line breaks which the code for it is CHAR(13). It will replace it with whatever inside the ""
