Iteratively Delete Rows From A Spreadsheet
Apr 13, 2009
I have a very large spreadsheet (about 50,000 rows, and to CM of columns) with blocks of data 20 rows high (rows 1-20 are from Building A, rows 21-40 are from Building B, etc). However, not every row in each block of 20 has information in it - some are just placeholders. For example, some blocks may have rows 1-18 filled with data while other blocks may have only 1-6 filled with data. I am interested in programming a macro that would delete the placeholder rows out of the spreadsheet based on a certain criteria. This would probably halve the size of my spreadsheet.
In faux-
For row i
i = 1 to 50,000
If Column B = #NA
Delete row i
Is this something that can be done with a macro, or do I need to go through all of these rows by hand? Obviously, I haven't programmed macros before (I've taken code and run it), but I've programmed in other languages (Java, C#). Could someone point me in the right direction?

I am trying to find the function or code in order to loop through and name each cell in a range iteratively.
For Example,
Cells A1,A2,A3,A4 would need to be renamed
so in psuedo code
name cell a1 ag.1
name cell a2 ag.2
name cell a3 ag.3
name cell a4 ag.4
Most of the naming is done in string literals which I am not sure how to get passed using a loop.

I have two tables, one summary sheet which contains a list of 30 projects. The second sheet has the projects broken down by task and status ("on time" or "late"), so it has three columns (project, task and status). I am trying to add up the number of projects within each task that are either "on time" or "late" and put these in two columns, so that the sum of each together will always equal 30.
The trouble is that any given task can appear multiple times for a project, and if one instance of that task is late, I want to count the whole project late for that task. Here is a table of what I am trying to do:
Project Task Status
A1 MU On time
A1 MU Late
A1 FA On time
B2 FA On time
B2 MU On time
B2 MU On time
The desired result of this scenario is that under task "MU" I would show a count of 1 projects on time (B2), and one that is late (A1). For task "FA" I would show a count of 2 projects "on time" (A1 and B2) and none for "late"
I think that an array formula is needed where it assigns a 1 to a project and task that is on time, and a 0 if it is not, and then multiplies these figures for each project and adds them up.

I'm trying to build a macro that iteratively runs a goal seek, then reduces a certain value (Let's call it "Bogey") in a different cell by a small amount (note that changing Bogey will affect the desired goal seek value), then runs the goal seek again, reduces Bogey by a small amount again, etc etc, and keeps running in this loop, with the restriction on this loop being that a different cell, affected by Bogey--let's call it "Constraint"--doesn't drop below a certain amount.

What I would like to do is delete all numbers including those with duplicates that have a date of 2004 or sooner. In otherwords, anything from 12/31/2003 and later I want to keep, but anything from 01/01/2004 until the present.

I'm trying to delete images from an excel spreadsheet. She had imported several Red "X" symbols and placed them at the bottom of the spreadsheet so that she could click and drag them to various spots on the spreadsheet when needed.
Well, now wants several of the "X" symbols to be erased...the problem is that they won't simply delete and when I click to drag them they stay in the same place and give me a duplicate to drag.

I have created a sample spreadsheet (the real data is sensitive) but I am basically faced with a spreadsheet of many columns of which I would like to remove the 4th,5th, 8th,9th, 12th, 13th etc...
So every 3rd column starting from Column B, and also every 3rd starting from Column C, (every 3rd, and every 3rd + 1 starting from B?), it's obvious what I'm after from the spreadsheet I've provided.
Unfortunately manually isn't an option, this needs doing every week, and it goes all the way across to column HZ!

I have a spreadsheet with over 20 tabs - each containing 6 text boxes containing financial commentary. Each month, the tabs are 'overpasted' with the latest month equivalents. This results in the latest month's text boxes sitting on top of the previous month's. I would like to attach functionality that deletes all the text boxes at the start of the monthly cycle - so the 'overpasting' exercise starts with a spreadsheet that contains no text boxes. I have been unsuccessfull with my attempts because each text box has a unique number - which changes every month. Does any VBA script exist to delete all the text boxes in a workbook or tab?
For reasons that are too longwinded to go into, there is no way around the overpasting set-up as summarised above (I recognise this is far from the ideal solution).

removing duplicate rows and move other data frm rows to columns.xlsx.
I am attaching a sample excel sheet showing what I need to do.In the first tab, I have a list that includes duplicate rows (first column only). I want to remove those duplicate rows but I don't want to lose the data in the following columns which can be unique or duplicates as well.
see the desired result tab in the sheet to get an idea of what I am looking for as the end result.
Keep in mind that the actual source file I am working with could have up to 50000 row, and the expected results could be around 2000 rows. So nothing can be done manually.

Is there a limit on the number of rows and columns that can be deleted in a macro on Excel 2003? I am trying to create a macro that, amoung other things, delets 1119 rows and 54 columns. If I delete the columns first, the rows will not delete. If I delete the columns first, the rows will not delete.

I am working with timesheet data (name, project code, task code, date, hours etc...) in one spreadsheet and rate card data (name, role, day rate etc...) in another.
My task is to pull together some of the information in each of these two source spreadsheets and compile a report. This I have done no problem. However, where a person works on a particular project and task on the same day and records multiple entries (which could be negative) I need to consolidate the hours in all these matching rows and have just one row reflect the total hours worked and delete the other duplicate rows.
So an example would be:
Project | Task | Name | Role | Date | Hours
123456 | 1.001 | Paul Jones | Project Manager | 20/02/2008 | 2.5
123456 | 1.001 | Paul Jones | Project Manager | 20/02/2008 | -2.5
123456 | 1.001 | Paul Jones | Project Manager | 20/02/2008 | 3.5
[Code]....
My problem is I don't think I have approached this the right way but am unsure of where to go with it. The code as is does sort of work but I still get some duplicate and zero lines in my results.

I need a macro that can look at multiple (say three) rows and delete those rows if they match another three rows in the worksheet.
For example:
1 0
3 1
5 7
4 4
6 5
8 3
1 8
5 2
3 9
6 5
8 3
1 8
7 5
If three rows are the same, then one set is deleted (it can be either bottom or top set). I would like to do this for rows 1-500 in the worksheet.

I have the following codes to delete all blank rows in column A
Dim lastrow As Long
lastrow = Sheet1.Range("A" & Rows.Count).End(xlUp).Row
MsgBox lastrow
With Sheet1
For t = 1 To lastrow
If Cells(t, 1) = "" Then
Rows(t).Delete
End If
Next t
End With
End Sub
Although it is working , it is not deleting all the blank rows at once, I have to keep pressing on the macro button running the macro several times, until all blank rows are completely deleted.

I have a worksheet in which I have sorted the data based in date and numbering (column I and E). I would like to create 2 macros for following actions:
1- all rows with the value "TOM" in column C will have to be deleted.
2- all rows with a value of 601 or 602 in column E, will have to be moved to the bottom of the sheet after the last row with data. The rows that have been moved will have to be sorted based in date (column I) and numbering (column E).

I have an imported report in a spreadsheet. It imports to three columns. I need to check each row in column A for three seperate criteria and delete the rows I don't need. I need to delete blank rows and check next row for page header info. Delete these and next rows to next blank cell. Check next row for page header and not delete if not page header. Several rows down will be a cell with 23 blank spaces before the word Reg: and sometimes other words past this but always this first. This row is to be kept. I looked at the FAQ's example of Deleting but I don't think it will work. I also need to put a key word in column A at a point where I want to stop. This report is a couple thousand rows long so a VBA procedure would really save time. I have a procedure I use to check for two zero's in two cells that hide these rows but I couldn't modify it to work on this report.

Need to solve my problem in the thread "Type Mismatch Error Message". Now a new problem has come up in the same code, so - according to the rules - I've started a new thread. (This one is most likely due to my poor knowledge of VBA syntax).
Sub Delete_invalid_rows()
Dim i%, j%
Dim Nr%, valid As Boolean, BYPdata As Boolean
Dim ar1 As Variant
Dim ar2 As Variant
Dim ar3 As Variant
Dim ar4 As Variant
Nr = 20
ar1 = Array(11, 14, 19, _
20, 22, 25, 26, 27, 28, 29, _
30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, _ .................

This sheet has A:K columns and 1:3212 rows. There are 'page headers' that are in the text file that I want to delete (the text file was exported from an AS400 program). The first row that starts the page header has SA341 in column 1. Each page header has 5 rows. I used this code from one of the other threads on deleting rows, but I obviously do not understand the code as it deleted all rows that contained SA341.
Sub DeleteRows()
Column_To_Check = 1
Start_Row = 1
End_Row = ActiveSheet. Cells(Rows.Count, Column_To_Check).End(xlUp).Row
MsgBox End_Row
Search_String = "SA341"
For Row_Counter = End_Row To Start_Row Step -1
If ActiveSheet.Cells(Row_Counter, Column_To_Check).Value < SA341 > Search_String Then
ActiveSheet.Rows(Row_Counter).Delete
End If
Next Row_Counter
End Sub

I am copying a price list from a worksheet. I currently have a script that deletes unwanted rows (products) but these products' header rows' are left. I also want to delete these text based headers. One solution might be a script that reads a columns cell value in the row(s) below and if values are missing the header row should be deleted.

I have got a spreadsheet with many rows of data. One row is product name and the other is date written. Now I want to calculate how long these entries have been on the log. So lets say I have 10 entries called Pension all with different dates and 10 entries called ISA with different dates. So first I need it to look for all the proucts called "Pension" and then to work out how many are 0-3 weeks old and so on. So i want it to look like this but a formula to work it out for me and to update it automatically.
0-3 Weeks 4-6 Weeks 7-9 Weeks 10 Weeks +
Pension 4 3 3 1
ISA 3 4 1 2
(this does not display very well here but I hope you understand what I mean)
I am using Excel 2003 and I dont think it as a WEEKS function so I will do it in days and then devide by 7.
I know that to look for the product i use
=COUNTIF(H:H,"Pension")
The H:H is because the product is on colum H on my spreadsheet
I know to find the date it is
=TODAY()
So to work out something 3 weeks old it would be
=TODAY()-21

I have a spreadsheet that contains traffic count data for a two lane road. The data is by direction, by hour, 24 hours a day, 365 days a year so the data is basically 2X 365 = 730 rows of data.
I need to simply add the two directions together for each hour of each day, basically add two rows together, drop down to the next two rows and add them together, repeat.
I need the result as stand alone data on another spreadsheet so the Data, Subtotals operation provided by Excel won’t work for me but something similar that puts the data on another spreadsheet would work.
I also tried to use a formula in the new spreadsheet that added two cells in two rows on the original spreadsheet together and then repeated that process a few times and then tried to drag the formula down but couldn’t get it to repeat correctly.

I've got spreadsheet I use to control the inventory of my user equipment; who has it, what is it, where is it, etc.
I'd like to "lock" multiple consecutive cells of each row so that they never seperate. This is because they need to be together. However, periodically, I need to move, sort, or rearrange the sheet.
Is there a way I can "idiot proof" this so that these cells never come unlocked from each other?
There is no vba involved (primarily because I don't know how), and no other scripting either.
