Calculation with comma separated values in a cell

[lind33]

I have an example ordered comma separated list in a cell. Values are comma separated. they can be 1 digit or 2 digits.

Book2.xlsx

I'm trying to get the difference between the first value and the last value, and add 1 to the result. This is what I tried to do:

B2: = (RIGHT(A2,1)-LEFT(A2,1))+1

This works fine if all the values are single digit, but if the last value is two digits, then it doesn't give the correct result.

Is there a better way of writing this formula which works fine both for single and double digits? please. thanks

On the link to excel file above, there are some data and expected results, and how the expected results obtained.

Hi
Try

B2==(MID(A2,FIND(",",A2)+1,255)-LEFT(A2,FIND(",",A2)-1))+1

I tried it but I'm getting #VALUE! error.

All right
I see
Use this UDF

Function calc(targetcell As Variant)
If targetcell <> "" Then
    x = Split(targetcell, ",")
     calc = (x(UBound(x)) - x(0)) + 1
    Else: calc = 0: End If
End Function

C1=calc(a1)

Thanks, Mohadin. the UDF works for all cells.

another option

=(IF(LEFT(RIGHT(A2,SEARCH(",",A2)),1)=",",RIGHT(A2,SEARCH(",",A2)-1),RIGHT(A2,SEARCH(",",A2)))-LEFT(A2,SEARCH(",",A2)-1))+1

Thanks, Fadee2. yes this formula works too.

@lind33
Mind you The other formula should be some thing like

=IFERROR((IF(LEFT(RIGHT(A1,SEARCH(",",A1)),1)=",",RIGHT(A1,SEARCH(",",A1)-1),RIGHT(A1,SEARCH(",",A1)))-LEFT(A1,SEARCH(",",A1)-1))+1,0)
