Find Duplicates Within A Percent Tolerance
Oct 26, 2008
Below is a short segment of my excel spreadsheet:
A B
1020.00242-89.84
1020 -88.11
1021 -85.3
1021.494-80.41
1021.49 -86.98
1030.04 -89.4
1030.042 -88.26
1030.94 -79.98
1030.933-81.5
1030.961-85.87
1040.0418-88.77
1040.391-87.3
1040.291-82.94
1040.016-84.12
1049.82 -84.7
What I need to do is write a macro that will find duplicates in Column A, within a changeable tolerance, say 0.1 (10%).
After finding all duplicates within a tolerance in A, I need to make another "Master" worksheet with the Duplicates from A, and their counterpart in B. So if A1 and A4 where within 10% of each other, the "Master" worksheet would contain:
A1 B1
A4 B4
using the values, giving:
1020.00242-89.84
1021.494-80.41
I tried using SUMPRODUCT and some other functions but just can't seem to put my finger on this one. I'm sure it's not hard and am overlooking something.

I need to be able to get a true/false from a tolerance percent.
Here is an example of what I am trying to do
cell a2 is Nitrogen
cell b2 is (Known gas%) 2.4800%
cell c2 is (unknown gas%) 2.4963%
cell d2 is =b2-c2 and I get the answer no trouble there. what I need is to take the answer in cell d2 and set a plus/minus 2% tolerance in cell f2 and get a true/false comparison.

I have a percent 3.14%, that I want to show 15, 20 and 25% above and below that percent. I am showing below the results and then formula. The top calculation results in the same on both the left and right. However the -15,-20, -25% results are different. Which is correct.
3.14%
20% +/-
3.14%
0.63%
or
6.28%
1.57%
2.51%
[code].....
basic math, but I don't understand why the results are different.

I use this formula to calculate if a move is out of tolerance =IF(ABS(B1)>=1,"Y","N") This will work on most of the stuff we load. I would like to modify it to if b1 = "Crude" then use =IF(ABS(B1)>=.5,"Y","N"), or if B1 = "Resid" then use IF(ABS(B1)>=2.0,"Y","N"). Is it possible to include the 3 tolerance bands in one formula?

I am successfully using VBA to check a cell on one sheet against a cell on another sheet.
How easy would it be to check if this is the same OR less than 2 or more than 3? I have done part of this using nested formulas but cant find anything to help me with the syntax in VBA
The code I am using is
If W1.Cells(a, 3).Value = W2.Cells(b, 3).Value Then

I have two numerical columns of different length. One presents the signal and another one the background. Most of the background numbers are found in the signal column but they are not exactly the same and not located in the same rows. The numerical values are the same within some tolerance that I can specify. What I am trying to do it to remove all the background values from the signal column.

I have a large amount of data pertaining to many different runs in which I am given the mass to charge ratio of a compound. My goal is to identify these compounds, and to ease this process I am trying to find a formula that would “line up” near identical masses while providing a blank if no mass was found in that run. For example, if I have:
Run1
185.041
196.073
200.454
667.175
Run2
185.040
196.074
398.452
667.175
Run 3…etc
I would like to have it arranged:
Run1Run2
185.41185.040
196.73169.074
200.4540.00000
0.00000398.452
667.175667.175
It would be important to have some sort of tolerance setting, as the readings are not always exactly the same. Also, I’d normally have about six runs of data to line up.

I am trying to replicate a method , it reads: 'any data point that changes by more than or less than 10% from the previous value, and does not remain at the new level for more than 6 days, should be removed.'
Thats a bit vague. The process is going to involve if statements, etc. I've attached an excel spreadsheet with some solutions I've tried. Neither of which work. The aim is to get the same answers as the highlighted column. Columns B and C replicate the method answer, but do not state the process. The letters L represent values less than 25. Its the letters D I'm trying to eradicate.

I have a sheet with numbers in descending orders with duplicate in one row and their respective value in 22nd row. I want to find the2nd occurrence of that value. (max. occurrence2 is 2)
Foe example
5----4-----3-----3-----2-----2-----1
A----B-----0---- C-----0-----D-----E

I am trying to apply conditional formatting to multiple columns based on a percentage varience of the value in the first cell of each column. I'm sure this is not a new concept however I have been unable to find any advice when searching. I have attached an example of my problem as a picture speaks a thousand lines of code.

I have a number of tables that may or may not have multiple dupliate enters, I am trying to indentify by name and by date. None of the tables are in the same format, which makes it ever harder for me, but all I want is a return of "duplicate" or "original", this will allow me to have acloser look at the duplicates.

I’m looking for a code that finds all duplicate words in column A & B and change the font of the found duplicate word in column B to ColorIndex = 11 and .FontStyle = “Bold”
I need this code to run frequently and possibly we can combine it with http://www.mrexcel.com/board2/viewto...272792#1272792
The wb is a dictionary and as I’m adding new words in new rows the wb needs to update. It is of course mostly important it updates when I open the wb, but it would be interesting if it could update for every new row (word) added as I might not want to close and re-open the wb just for this.

I have a long list of checks and I need to find the duplicates, determine how many dupicates there are for a given check (the criteria is if the ENTIRE ROW is dupicated), and highlight HALF of the duplicated rows.
I am able to sort the table however needed.
Here is the logic I was thinking of following..
If Row is Duplicated
Select Case Boolean
Case True
Count how many are duplicated
If count is even then
NumberToDelete = Count*0.5
For i = 1 to NumberToDelete
Highlight one of the duplicated rows in red background
Next i
Else
Next Record (do not highlight anything)
End If
Case False
'Nothing
End Select
End If

I'm trying to find duplicates in one particular column. I'm using this formula =if(countif($A$1:$A:$300,A1)=1,FALSE,COUNTIF($A1:A1,A1)=1) in the conditioning format tool but here's my problem:
I'm noticing that some of the cell values have spaces after the entries so the formula is not picking it up as a duplicate. Is there a quick way to remove those unwanted spaces after each entry?

I need to find duplicates subnet information in row F and mark the words "Duplicate"
Then I need to do the same with Row K. I need to find any duplicate subnet masks.
The reason for this is that I merged two orginizations into one spreadsheet and I need to find the duplicates in Company A and Company B's subnet and mask information.

I'm trying to identify where a set of values 'agree' within a specified tolerance.
I have a list of scores from different sources, and wish to both average them (easy to do) but also to identify how well they 'agree' by flagging those which have a difference above a specified tolerance. The numbers are all integers, and the tolerance will be an integer.
To give an example, I might have cells with values (2,3,2,2) and these agree within a tolerance of 1. If I had cells of (2,4,2,2) these wouldn't agree. I'd like to flag (by the creation of an 'X' within a separate column) where these cells do not agree.
I've done this previously by using chained If and Or statements (e.g. if A1 = D1 or A1 = D1+1 etc etc) but this is laborious and means I have to change logic every time I add a new sample.
Is there a way of specifying a range of cells (e.g. A1,D1,H1, J1) and seeing if the values of these cells agree to within a stated tolerance? I'm happy to define named cells to specify and argument/attribute.

a lookup and match of two values.
For example, in Sheet1 I have a unique transaction reference number and a £ value.
eg. 60231568 £38.05
In the next sheet (Sheet 2), I have a summary of data, and I need to return the company name...
60231568 £38.04 Company X
60231568 £15.12 Company Y
60231568 £10.11 Company Z
60245871 £105.11 Company Q
The look up needs to match trans no, amount (within 3 pence threshold) and return in this example company X.

I have an unknown number of rows that represent parts and 6 columns that represent part dimensions. I need to find and output matching pairs of parts that are within certain dimensional tolerance ranges.
For example:
Dimension 1 Dimension 2 to Dimension 6
Part 1
Part 2
to Part X
-I would need the code to check if Dimension 1 of Parts 1 & 2 were within a certain range and if Dimension 2 of Parts 1 & 2 were within a range etc. then (if all of them were true) output them as a pair. Otherwise, it would continue to search for paired parts. Once a pair is found, those parts can't be used again. How can I do this?

I have a DDE linked cell that is constantly updating (cell A1), I want then to have a cell (cell B1) that changes only when cell A1 differs from value currently in B1 by a certain percentage, then check B1 for the same tolerance level against A1, and repeat. I can do this in a number of ways in VB, however when VB code is running causes the DDE link not to update and since the update is constant I cannot use selectionChange and Change VB Worksheet function result in the same error.

I have a table that looks like this:
ID
HostLocation
NDaysinHost
marina.silva
USA
100
[Code]....
I would like to obtain a table in the following format where I can find
ID HostLocation NDaysinHost
marina.silva USA, Norway, Bolivia, Italy, Ecuador... 100,45,67,8,9...
tatiana.gottig Venezuela, Chile, Peru, Canada 89,54,32,6
Searching in the net I found the following code:
VB:
Sub groupConcat()Dim dc As Object
Dim inputArray As Variant
Dim i As Integer
Set dc = CreateObject("Scripting.Dictionary")
inputArray = WorksheetFunction.Transpose(Sheets(1).Range("A2:C9").Value)
[Code]....
However I only obtain the first two columns concatenated. It says that for more columns repeat the loop, however I did and the result was not the expected, it returned me the same two columns again concatenated. How can I arrange this to fit my criteria?

I have a sheet which contains more than 8000 names (in 1 column), & another sheet which contains around 600 names (in 1 column), is there any way wherein i can compare both the columns & find out duplicates if any?
Sheet which contains 8000 names contains duplicate cells as well, but dat doesn't matter, i jst need to compare & confirm the sheet which has 600 names should be unique (Not included in 8000 data)

I want to search a worksheet for rows that share the same value in two columns (columns C and E). See the attached excel file.
I have highlighted in yellow some rows that have duplicate values in row C and E.
So in this case rows 14 and 19 will be hidden but rows 13 and 17 will still be visible.
Note that this must work properly reguardless of how the data is sorted.
In other words, there can never be more than one row that has the exact same value for both column C and E.

I run an online baseball league, and the game I use to simulate our games has issued a new version which has updated ratings for all the baseball players. I have exported rosters from the new game and rosters from my online league to .csv files and what I want to do is find which players are duplicates in both files and line them so that I can scroll both files simultaneously and update my online league file easily. I also want the non-duplicate players to be sorted below the duplicates so I can deal with them later. Someone on the other forum posted some dynamic named range code and two macros and gave me some vague instructions on how to use the codes. I have posted the codes below with their instructions:
In both:
a) There're defined 2 dynamic named ranges:
"DataTable" as: =DESREF(INDIRECTO(DIRECCION(COINCIDIR("//Player ID";updated_rosters!$A:$A;0)+2;1;1;1;"ml_rosters"));;;CONTARA(updated_rosters!$A:$A)-

I'm supposed to find duplicates in sheet_1 Q6:Q251 and copy one of each to sheet_2 D6:D243 as well as unique values from the same column. In a sheet_1 B6:B251 I have values related to Q6:Q251 and I have to copy each of them to sheet_2, E6:I6 in the same row as the related duplicate (I'll have max 5 duplicates). You can find attached simple example of what should be the result (sheet_2)

I have two worksheets (sheet1(1687 rows), sheet2(767 rows)). Both have part numbers in Column A
I want to be able to search Column A for duplicates found in the other worksheet. When it finds those duplicates, iw oudl like for the Part Number(columnA) and the cost(column D) to be pasted onto a third worksheet (sheet 3)
I have found lots of similar things out there, but nothing that does what I want.
I will do this Each Monday morning. I am ok with VB but what takes me 3 weeks sometimes takes you guys 10 min.

Let's imagine I have many informations about 'Domains' such as Emails, phones, etc. My lists are long and it happens very often that I have the same domain (row) many times. No way to remember each time if I already filled the informations for this specific domain before.
THat's why I want to know if there is a way that ALL the informaitons on the Row of : Domain A will automatically be copied to another row where it will find another Domain A
The Conditional formatting (highlight duplicates) do part of the job by telling me where are the duplicates, but i need the other infos to be copied.
