Indentify value from multiple values in a single cell

[Guest]

I am looking to produce a formula that shows if a number is "found" or "not
found".
I have list of over 1000 numbers in one column (1 number per row) . I am
trying to identify if those values are present in a range of numbers from
another worksheet(also in a single column). My challenge is that the range of
numbers that I am looking in has multiple values, separated by commas in a
single cell. Looks like it was from an Access data dump. Any help is
appreciated.

Can you post a small example?

If you data looks like this:

Column A

45
1
84
99
8

Column H

1,12,20
32,44,55
18,99,65

In column B enter this formula and copy down:

=IF(SUMPRODUCT(--(ISNUMBER(FIND(","&A1&",",","&H$1:H$3&",")))),"match","")

Column B will return "match" for 1 and 99

=countif(sheet2!a:a,"*"&a1&"*")>0

Will return True if it's found.

You may want to check for empty cells:
=if(a1="","",countif(sheet2!a:a,"*"&a1&"*")>0)

or

=isnumber(match("*"&a1&"*",sheet2!a:a,0))
or
=if(a1="","",isnumber(match("*"&a1&"*",sheet2!a:a,0)))

Suppose the number in A1 is 1.

Sheet2!An = 11,21,31

=countif(sheet2!a:a,"*"&a1&"*")>0 returns TRUE

Biff

 

[Dave Peterson]

Yes it does.

Suppose the number in A1 is 1.

Sheet2!An = 11,21,31

=countif(sheet2!a:a,"*"&a1&"*")>0 returns TRUE

Dave, Bif,
Thanks for the replies. I am a lot closer than I was. Is there an addition
to the formula that can give me an exact match? The example that Bif wrote
below is exactly whats happening with some of my data.

Did you try the formula I suggested?

It will only "work" for exact matches.

I should have been more specific!

Use Biff's formula and toss mine in the trash!

Biff,
I finally got it to work. In the cells that had multiple values there were
spaces between the commas and each value.That was causing the formula to only
return the first value in each cell. I t"tweaked" the formula you wrote to
add a space with the commas in quotes and it worked perfectly.

I appreciate yours and Dave's responses to my question. It certainly saved a
lot time and was much more efficient.

Thanks again, Dave
