How Do I Conditionally Delete Duplicate Entries?

Aug 8, 2008

I have 2 columns of data, apprx. ~25,000 rows.

Col 1 is user IDs and Col 2 is there status (pending, conditional, approved, rejected)

Col1 IDs are not unique because they can have multiple statuses associated with them in Col2. An ID can go from pending to conditional to either approved/rejected and all these are included in the raw data file. I want to remove all duplicate ID rows and keep the ID row with the last known status.

For example:

I have one sheet that have +/-5000 data in 4 table ... all table is fill with just only 2 column, first column is Code Number and second column is Quantity.

There are many duplicates of different entries in Column 1st in all table range and I need to add up their quantities to new table in new sheet...

This is for example:

Delete Duplicate Entries, Keep Last And Delete First

Feb 15, 2010

I found this sample code that works from top to bottom of a spreadsheet. But I need something that will delete the first entry and keep the last entry. My data is sent from one spreadsheet to a Master and sometimes the details can be sent twice, if the responsible person forgets to enter one line of production. The criteria should be the first 5 Columns of the sheet.

Sub Dupe_Killer()
Dim str As String
Dim str2 As String
Dim c As Integer
Dim i As Integer
Application. ScreenUpdating = False
Application.Calculation = xlCalculationManual
Sheets("SAMPLE").Select
rw = Cells(2, 1).End(xlDown).Row

Delete Duplicate Rows Containing The Oldest Date And Time Entries?

May 23, 2014

I have a UserForm which writes data to rows in a master spreadsheet. I'm attempting to write some vba code for a CommandButton in the master spreadsheet which can identify and delete duplicate entries based on "user ID", "Date", and "Time". I would like the CommandButton to retain the most recent entry from a user and delete all previous entries.

My master sheet is set out as such...
A, B, C, D,
UserID, Date, Time, Response

The users could potentially submit multiple entries on the same day. Ideally I would like to be able to click a CommandButton and delete each user's submission but retain their most recent one (based on "UserID", then "Date", then "Time").

I've searched all day for a solution and I've come close but I can not figure out a code that accounts for my three variables ("UserID", then "Date", then "Time").

How To Exclude Duplicate Entries With Multiple Condition

Jun 4, 2014

My data set has a number of duplicate entries. But I would like to sort them out based on some conditions. Say for example my C2 code appears three time in the dataset. I would like to sort this multiple code using the time and i column.

Say for example, 871514 code appears three times in this dataset, and if this code appear within three years - time with a different (i column text e.g. public and private), I would like to exclude these three duplicate entries from my dataset. If this code appears within next three years from the date, but have same I column text (e.g.public versus public), I will keep them.

So each code will be considered based on three years of time and type of text in I column. If the code appears again later after three years, I will keep them.

So the codes need to be checked within three years time with i column text.

My dataset identifies the difference of dates between last entry and next entry.

Macro To Delete Duplicate Values But Keep Last One?

Dec 21, 2012

I am looking for some VBA code that will look through a column and delete all but the last duplicate value. The rows are not to be deleted. The duplicate also may not be consecutive (i.e they may appear in rows 2, 3 and 72 - the one in 72 would need keeping).

I did find the following macro which seemed to do the job until I realised it wasn't working if the values weren't consecutive.

Find Range And Delete Duplicate Value In Specified Column With VB Macro

Apr 21, 2009

See attached doc "Find and Delete.xlsx". Inside, the value in F12 is a very important cell. Using the text value from F12, I first want to use visual basic code to find the range in column B because it will vary. This means the 'text words' column might have 50 words or it might have 2000. I have racked my brain trying to find a universal way to find a variable range.

Then I would like to search for the exact text value within this range in column
B. For example, in F12 is the text word 'windows xp registry cleaner' and you can see that this value is in B9. There will only be one exact match in column B.

I then would like the vb script to delete and remove this found value, then move left one space in column A to also delete the ID number associated with the text word. Then shift both rows up to fill the empty gap. I have tried numerous different codes but to be honest, I'm not really sure what I'm looking for. I've tinkered with find and replace, vlookup, match, find, search, and many more.

Excel 2010 :: VBA Code To Search Multiple Columns And Delete Any Duplicate Cells (not Rows)

Jun 12, 2014

My Excel program (Excel 2010) currently has several columns and each column looks for and pulls data from a specific file on my computer. Then I need to delete any duplicate data entries, count the number of unique entries and track the changes through a chart. I have everything done except I cannot figure out (or find on the internet) a way to search in multiple columns (more than 2) and delete just the duplicate cells. I want to delete the cells in a way where there is one left. For example if the code 12gf is duplicated three time, I want to be left with one 12gf (it doesnt matter what column the original one is left in). Additionally, column length changes and they are not sorted. I have attempted to attach an image of an example file below.

Macro To Delete An Entire Row If A Duplicate Entry Appears Only In A Certain Column.

Feb 20, 2009

Is there a macro to delete an entire row if a duplicate entry appears only in a certain column.

1. Look for the column header with the name "File Number"
2. Anytime the same number under the "File Number" column appears more than once in that column, keep the row that contains first occurrence of that number buy delete the entire row anytime that number is repeated in another row in that same column.

This is regardless of what is contained in the other columns. For example..let's say these cells contained this data...

B1 - UTE00225
B2 - UTE00546
B3 - UTE65513
B4 - UTE00225
B5 - UTE00225

In this case, I would want to keep rows 1, 2, and 3. But, I would want to delete rows 4 & 5 because the number "UTE00225" has already appeared first in B1. I'm using Excel 2003.

XL Macro For Searching Column For Multiple Entries

The code I currently have allows me to search for one text entry in the column and then copy and paste all those entries into the next worksheet. There are 5 different text entries I'd like it to look for but can't figure out how to do it. I have a work around by using wildcards, but then I have to write another macro to delete out the ones I don't want.

Where is says "DNA - weapons", I'd also like it to allow for "DNA - paternity" and a couple other options.

Here is my current code:

Dim FirstAddress As String
Dim myArr As Variant
Dim Rng As Range
Dim Rcount As Long
Dim I As Long
Dim LastCol As String
Application.ScreenUpdating = False

I have been trying a number of different functions!

I have the following countif function that is searching a worksheet (Cases Closed) for the name John in Column O and excluding Solutions in column x. The problem I have is there are duplicates cases in Column C that are being counted two and three times.

I have some code but I still need to do a considerable amount of tweaking to it. Currently my code is only deleting the duplicate values in Col A. I am having difficulty summing the values in Col D as well as deleting the entire row.

Here is my code thus far....

-------
Public Sub FindDuplicates()
For RwCnt = 1 To (Worksheets(1).Cells(65536, 1).End(xlUp).Row)
SrchValue = Worksheets(1).Cells(RwCnt, 1).Value
If Len(Trim(SrchValue)) > 0 Then
With Worksheets(1).Range("a1:a" & Cells(65536, 1).End(xlUp).Row)

How To Combine Duplicate Entries

Apr 23, 2013

excel.jpg

Basically I've made this up myself because what ill be working with has 100s if not 1000s of rows with many different product numbers that's quantities are different. What I've been able to do up to now is sort the spreadsheet by the product number so all the same rows are next to each other. My problem is however I need a speedy way of making these duplicate rows become one but add the total quantity basically everything in the left screenshot into the one on the right. What I've tried up to now is sorting them so there together and manually adding them up and putting them into one of the rows quantity, then delete the rest. takes to long. Another was to make a row underneath the rows I need into one but that takes more time than manually adding and deleting the rest.
