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)

Compare Lists & Highlight Duplicates

Jul 3, 2007

I receive a daily spreadsheet which contains (amongst other information) a column of postcodes. I'd like to run a macro which compares these postcodes with a list of other postcodes, and then to colour highlight each instance of that post code in the daily spreadhseet.

I have been able to find and modify a macro but that searches for one post code at a time and then adds a comments box to the cell.

Instead of copying that piece of code and editing it for the several hundred post codes I need to "look up" against, I'd like to know how to create a list of post codes in the macro, so that the macro searches the first post code in the lookup list, finds and highlights each cell instance, then moves onto the next post code in the lookup list, until the end of the lookup list. I would like this as the editing of the lookup list would be much easier than editing paragraphs of code.

Compare Multiple Columns - Flag Duplicates?

Nov 14, 2013

Columns A, B, and C have data (first name, last name, state) - 125k rows. Columns F, G, and H have data (first name, last name, state) - 5k rows. Some of these individuals are bound to appear on both lists, and I need to know which ones are indeed on both lists. So in other words, let's say I've got "John" "Doe" "TX" in cells F1, G1, and H1, respectively. I want to search through columns A, B, and C to find out if there are any instances in those columns of "John" "Doe" "TX" in the same row.

I'm thinking there will be multiple VLOOKUP formulas involved, but I could be way off.

Compare Two Lists & Save Duplicates To New Sheet

Jan 11, 2008

The Master list:
Sheet1, Column C has unique numbers, i.e, 0608-211-1093-2.

(can have thousands of entries)

The Comparison list:
Sheet2, Column C will have duplicates of some of Sheet1, Column C numbers.

(Sheet2, Column C will have the numbers but other columns will have different
data than Sheet1 and may have a few hundred entries or less)

I need a macro that will that will compare the two sheets for duplicates based on
Column C and then write the entire row of Sheet1 with the duplicate number to a new Sheet3.

Compare Number Lists On Different Sheets And Delete Duplicates

Mar 26, 2011

Need to find a column of numbers from one worksheet and delete them from another.

Example
To be deleted is below:
83221
83223
83232
83233
83236
to be deleted from is below:
83221
83223
83226
83227
83228
83229
83230
83232
83233
83234
83235
83236

Another issues is that the worksheet that needs to have the numbers deleted from has 3 columns total so the whole row would need deleting, or if its easier I could replace the numbers with 0 and then sort and delete.

Code To Find Duplicates

Mar 26, 2007

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.

Find The Duplicates Values

Jul 18, 2008

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

Find Duplicates In One Particular Column

Dec 4, 2008

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?

Macro To Compare Columns A & B And Dispaly Any Duplicates In Columns C & D

Feb 21, 2009

what I'm after is a macro to check the contents of Column 'A' against column 'B' and display any duplicates in Columns 'C' & 'D'.

N.B. The headings of Columns C & D are :-

Any duplicate entries logged in columns C & D should be listed in C2,C3,C4....C20 and D2,D3,D4......D20 etc (in effect creating two new lists)

Code To Find Duplicates And Concatenate In One Row

Nov 20, 2013

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?

Find And Hide Rows With Duplicates

Aug 28, 2009

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.

Using Macros To Find Duplicates In Two Spreadsheets?

Apr 19, 2014

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)-

[Code]....
