Identify Duplicates

Nov 9, 2009

I have two worksheets one worksheet contains Insurnace names and Addresses from a hospital. I need to match these up to specific Insurance codes from a billing company worksheet. The bad thing is my billing database has multiple duplicate addresses for different insurances (Yes this does happen where different Insurances have the same address-don't ask me why). So originally I did a VLOOKUP where I looked up the address from the hospital Spreadsheet and matched it to the Insurance Specific code. The pitfall to doing it this way is that it only grabs the first exact match from the Billing worksheet. Is there a way to either automatically identify the possible matches and allow me to choose which one is the exact match or how do I just identify duplicates on my billing worksheet and match them manually? I attached the worksheet.

Not sure which formula to use. I tried CountIF but didn't work with 2 sheets.

Identify Duplicates In A List

Oct 13, 2006

I need to identify duplicates in a list and have the foilowing formula:

=IF( COUNTIF(range1,A2)>1,"Duplicate","")

This works ok but i have a further condition which i dont know how to factor into the formula. I think i could write some vba to determine the dupes but i was hoping to avoid this as im sure it will take me an hour or so. Duplicates are identified at the moment as being identical numbers in column "amount", i now need to specify duplicates as being identical numbers in this range where there is at least one row with no pay date filled in in col "paydate"

Identify Duplicates Between 2 Columns Of Different Sheets

Mar 14, 2008

I have two spreadsheet in which I am looking for duplicate customer names.

1st - "Customers"
2nd - "Orders"

In column A of my Customers spreadsheet I have the following formula
=IF(ISERROR(MATCH(E2,Orders$D2:D1000,0))=FALSE, "Y","N"). This allows me to see if a name in my Customer spreadsheet (column E is a field of names) is also in my Orders spreadsheet (column D is a field of names). My end results is either a Y indicating a duplicate or a N for no duplicates.

What I am looking to do next is to place in column B of my Customers spreadsheet the date that coincides with the duplicating customer name. Sorry to be confusing. If a customers name is found in the Orders spreadsheet I need to know what date has been given to this customer (column L in the Orders spreadsheet contains the date information).

However, on numerous occasions a customers name is found in the Orders spreadsheet more than once meaning there may be more than one date which needs to be placed in column B of my Customers spreadsheet.

Identify Duplicates Across Multiple Colums And Rows

Dec 22, 2008

I have a spreadsheet with 20+ columns. Each column contains a list of invoice numbers, eg, 1234. The lists are all of different lengths (see below). I want to find a way to find/highlight/identify those invoice numbers that appear more than once in the entire sheet (eg if invoice 1234 is listed in column B, and also in column H, and/or if invoice 5678 is listed in column A, and also in column J, and also perhaps in column D, etc.)

I've searched this forum but haven't found anything about searching for multiple duplicates in multiple columns. Ideally the matches would be highlighted in different colours, (eg all cells that contain 1234 would be red, those that contain 5678 would be blue, etc., for ease of identification) but I'm not sure if that's possible. I've attached an example that I've shaded myself to show what I mean. I've tried the MODE function but that only tells me which invoice number occurs the most.

Review List Of Numbers And Identify Duplicates In Order

Feb 24, 2014

- I have a list of 8 digit numbers in Column A sorted small to large
- Some of the 8 digit numbers are duplicated.
- In Column B I would like to have more of a combination of countif and listing the duplicates in order (1 for the first dup in the column, 2 for the 2nd, etc.)

Example of what I'd like to see

Column A Column B
123456781
123456782
132546841
685036541
985413561
985413562
985413563

As you can see if the number in column A is on the list one time column B would show a 1If the number is shown two times (the first time it shows up will show a 1 the second will show a 2) If the number is shown 3 times (the first time it shows up will show a 1 the second will show a 2, the third tiem would show a 3)

Identify The Errors, Duplicates, Typos And Such Between Two Spreadsheets Of Over 4000 Rows Of Data Each

Jun 29, 2007

I need to identify the errors, duplicates, typos and such between two spreadsheets of over 4000 rows of data each. The Macro: I got a macro working, but it's not perfect. So far, it can only tell data that's missing on spreadsheets A, or B. However, it can't tell which are the duplicates, typos, etc. Please look at the sample for more details. The code is included in the sample. And for your convenience, it's right here:

Sub difference_general()
Dim frontcount As Long
Dim backcount As Long
Dim diffcount As Long
Dim nosrcflg As Boolean
Dim front_ref As String
Dim back_ref As String
Dim anydiffflg As Boolean
Dim ftnotexistflg As Boolean
Dim invnotexistflg As Boolean
Application. ScreenUpdating = False
Application.Calculation = xlCalculationManual
Sheets("Diff").Select
Cells(1, 1).Select
Rows("2:65536").Select
Selection.Delete Shift:=xlUp
Cells(1, 2).Select............................

Identify Part Of String In One Column And Return Entry In Neighboring Column?

Feb 28, 2014

I have a spreadsheet of several thousand named items (in column B) with values associated with them in column A). The "name" field is a string of several alternative names for the item.

I have a list of ~50 items that I am trying to find the values for. Each uses one of the alternate names.

What I want is a function that will return the associated value in column A when one of my shortlist names is found.

For example, my big spreadsheet looks like:

AB
1dallas, DFW. 12345
2Atlanta, ATL, 23456
3Boston, BOS, 34567
4Chicago, CHI, 45678
5Los Angles, LA, LAX, 56789

And my list looks like

Atlanta
CHI

I want the output to look something like:

Atlanta2
CHI 4

Is the feasible? IT seems like there should be a way to do it....

How To Identify Column Position Based On Lookup Value

Nov 10, 2011

I will be working with an array of data approx 500 rows by 50 columns (eg Sheet1!$A$1:$CV$500) in which I will need to check if approx 1000 unique values exist and in which column they appear in. Each unique value should not appear in more than 1 column. Once identified, I need to return the header value at the top of the relevant column.

My thoughts on approach would be perform a lookup of some sort to identify the column number and then use that within an index formula to return the header value based on the column number.

However, I'm not sure how to perform a lookup to get the column number. A match formula can, as far as I am aware, only lookup against a single column or single row.

Identify MAX Value From Two Columns And Display Result In Other Column In Pivot?

May 30, 2013

I have a pivot table and perhaps that isnt the best way to do this. (Sample attached). Ultimately I need to display two columns only:

Application (ColA) Business (ColC)

There are three columns of data.

Applications (ColA) Usage(ColB) Business (ColC)

There are multiple instances of the same application in ColA, ColB has usage =true or blank and ColC has multiple instances of the same business.

Based on the count of Application in ColA, and the count of Usage =True, I need to return the Business with the MAX count.

Note: the usage cannot be a filter, it must be a count.

Identify Specific Keywords (plural) In A Column Of Text

Nov 3, 2009

So i'm try to automate a process that I currently do using filters.

Here is the problem:

I have a list of text in a column (usually 700 or so entries).

I need to remove any entries that contain 1 of 42 keywords.

So I need a fast way to search each cell for each one of the 42 key words and flag the cell for deletion if contains anyone of the 42.

example
A
1 This field has keyword1
2 This field has keyword2
3 This field doesn't have any of the 42 keywords

somewhere else I would have a list of keywords in a column.

Find Duplicates In Column A And Calculate Difference Between Times In Column B

Apr 4, 2009

I love this forum, and am usually able to find the help I need without bothering anyone However this one has me stumped and I wonder if anyone can help. It feels like it should be a fairly simple solution, but they can often be the ones that are most eluding LOL!

I have two columns; in column A are incoming telephone numbers and in column B are the date and time the calls were made. (I've put a few hashes in column A just to maintain confidentiality of the numbers, but in reality the cell is formatted as text in order to maintain the leading zero, and entries will follow the format 01234567890)

A sample would look like this:

0##6270####01-Mar-2009 00:01:440##6271####01-Mar-2009 00:03:020##6271####01-Mar-2009 00:03:040##6272####01-Mar-2009 00:16:330##6273####01-Mar-2009 00:30:490##6274####01-Mar-2009 00:55:470##6274####01-Mar-2009 01:06:170##6274####01-Mar-2009 01:07:420##6275####01-Mar-2009 01:08:360##6275####01-Mar-2009 01:11:410##6276####01-Mar-2009 01:13:45

Some numbers only call in once, I need to identify them as only called once.

Some numbers call twice, if they do I need to be able to show time it took between call 1 and call 2.

Some numbers call more than twice. For each successive call I need to be able to show the time since the previous call.

In my mind, the results table would need to look something like this:

NumberTime of callTime between
1st and 2nd call
Time between
2nd and 3rd call
Time between
3rd and 4th call
0##6270####01-Mar-2009 00:01:44Only called once0##6271####01-Mar-2009 00:03:0200:00:020##6272####01-Mar-2009 00:16:33Only called once0##6273####01-Mar-2009 00:30:49Only called once0##6274####01-Mar-2009 00:55:4700:10:3000:01:250##6275####01-Mar-2009 01:08:3600:03:050##6276####01-Mar-2009 01:13:45Only called once

How To Generate Dropdown List With Data Which Uses Column To Identify Items

Apr 18, 2014

I have in column A and B. A includes two (or may be more) kind of items, i.e. drink and snack. Column B has for example water next to drink and chips next to snack. The list is huge.

How can I generate a drop down list with data which uses the A column to identify the items which it should include. I want to make two separate drop down lists for drink and snack and each should include only those options which belong to those categories. I.e. drink list should be like water, cola, pepsi, etc. The problem is that the list is huge and it's not possible to sort it. Some kind of if statement structure with named range? The drop down should be dynamic in a sense that if I add line to data, it should be picked to the right drop down menu.

Excel 2007 :: Remove Duplicates In Column B For Each Value In Column A?

Jan 8, 2014

I need to remove the duplicates under column B for each item under column A and I can't seem to figure out how to do it.

I'm using Excel 2007; I would prefer a VBA solution, as I have to do this on a monthly basis. However, if a formula is the best way to go, then that's just fine. Either way, I'm preparing the data for a pivot table. I am unable to post the actual document in the interest of data protection.

Essentially, I'd like to turn this-

_ A B
1 Paris Bill
2 Paris Bill
3 Paris Mike
4 Paris Derek
5 Paris Derek
6 London Mike
7 London Bill
8 London Mike
9 London Bill
10 London Derek
11 Tokyo Derek
12 Tokyo Derek
13 Tokyo Derek

into this-

_ A B
1 Paris Bill
2 Paris Mike
3 Paris Derek
4 London Mike
5 London Bill
6 London Derek
7 Tokyo Derek

In other words, each city should have only one instance of any name that accompanies it; not all names will accompany each city.
