It takes all numbers in column 4 starting with Row 15 and deletes all duplicates. It then shows the number of times the number was duplicated and puts this number in column 3. MY PROBLEM: The macro searches each line and takes FOREVER! I have data with thousands of lines. I already tried the screenupdating method which really doesn't help that much. Is there possibly a better code for doing this?

I am trying to parse and remove unwanted rows from a very large text file using At the moment, the application runs rather slow and was wondering if the experts could give some pointers on how to make the code more efficient while still keeping it simple so others may be able to modify later. I am keeping the ScreenUpdating True as the alternative false will just show Excel as Not Responding to the user until the VB is finished.

I need a macro that searches my spreadsheet for a keyword in Column B. If it finds the keywords (or an array of keywords would be even better), it then deletes the entire row above the keyword, the row with the keyword, and the row below the keyword.
If the macro finds the text in column 2, it would delete 1, 2 and 3.
I need to have a second macro that performs a very similar function. it copies the 3 rows (similar to the example below) to a different sheet based on the keyword.
I’ve got a macro that automatically starts when the workbook is open. The macro finishes with
Application.Dialogs(xlDialogSaveAs).Show
The document will be always saved with a new name. As I just need the macro once when the workbook is created I’m looking for a code that deletes the macro before the workbook is saved. I tried to record a macro while I was deleting another macro, but apparently it is not working (the recorded macro is empty). Does anyone know if there exists a code to delete a macro?
i have this macro made by another member here that looks for "T" in column 10 and deletes entire row if in that row has a "T". I need it modified to also delete if it contains "FT" and also erase if cells is blank.
Sub Macro8() Sheets("FORMERS").Select 'deletes entire rows based on a text on one row (this case errases all that have a "T" in column 10 (column J)

I have a macro that that stops every time I’m trying to delete the sheet. I get this message. “Data may exist in the sheet(s) selected for deletion. To permanently delete the data, prese Delete.” and I have to manually click “delete” to continue running the macro. How can I avoid this stop so that macro runs thru it without stops?
I need help writing a macro. I only have experience recording them, not writing them in VBA.
I need to check columns A and B for blanks. If A and B are both blank, I want the macro to delete the row and move on to check the next row. I need to perform this macro for the entire worksheet.
I need a Macro that deletes all cells in column D of all worksheets in a book that are equal to the word "Timeout" and to shift the cells to the right of the "Timeout" cells into the deleted cells but leaving all other rows where the word "Timeout" is not present.
So in the case of Rows 2, 4, 6 and 8 containg the word "Timeout" in column D, I would like cells D2, D4, D6 and D8 deleted and the remaining cells shifted to the left but cells D1, D3, D5 and D7 left as they are.
Dim rng As Range Dim i As Integer, counter As Integer
Set rng = Range("1:1")
i = 1
For counter = 1 To rng.Columns.Count

My problem is that I have cells in other worksheets linked to the worksheet that is running this macro and everytime I run it, I get a handful of "#REF" errors. I think this problem might be solved if I could simply delete the contents of the column rather than deleting the entire column. How can I modify my code to do this?
how to put together a macro for a command button that deletes rows with certain text in a docyment - which worked fine a week or so ago - but now the macro will not work.
I made changes to the document - but made sure i also made changes to the code.
The macro clears specific columns in a row when you click anywhere on the row and then hit the command button. It clears the first range and 2nd range in 2 distinct steps, and takes up to 3 seconds.
I am having a big problem with recalculating cells after running a macro. The macro runs at a great speed, but once the calculation is switched back to automatic, the cells are not calculating fast enough. I waited for 4 minutes and it still had not moved past 0%. The worksheet has approximately 9000 rows out to IG columns. 85% of the cells contain an if-then formula.
I have this analyze that is runned by a macro in one workbook, and it starts a analyzing-process in another workbook. The data is picked up in the no2 book, and returned to the first book. It is analyzing lots of workbooks, sometimes up to 1000 workbooks, it means that no2 workbook gets a new name and then saved.
I have once heard that the process could be way faster if the workbooks where the analyzes is processed through not were saved, and I actually dont need the books as long as I got the data into my first workbook.
But Im not sure what in the macro that makes it save the no2 workbook, but I would really like to speed up this process. As it is now I have to start the analyze before I go to bed, and the hopefully it's done when I wake up next morning.
I wrote a macro that works fine, although it runs extremely slowly as if plodding along through all of the cells one at a time. I'm sure the computer is faster than that, so I would like it to chug through more quickly.
I am using some syntax that could be optimized ....
I'm trying to determine the speed of a macro. I searched and have had no luck. recently with some help I reduced my macro speed from minutes to seconds and I was wondering is there code out there that I can record the speed of an existing macro.
This is weird - if you delete a sheet that contained a control then
a. showing a modeless userform resluts in a userofrm that goes invisible at subroutine End b. public variables lose their value
These things do not happen if the sheet did not contain a control. Attached is an example file - put the inputfile.xls in your default file location (or add a path in the code) then open the ProblemDemo.xls and run the main macro to see it fal - isthis another Excelbug I've found?
I am dealing with data sets from various instruments that have different sample rates. I am deleting data points I don't need from some of the sets with higher sample rates so that all the data is on the same time scale.
The macro I have is super simple, but incredibly slow. I'm simply deleting every other cell down a column.
VB:
Sub OATcondense() Application.ScreenUpdating = False Do While ActiveCell <> "" ActiveCell.Offset(1, 0).Delete Shift:=xlUp ActiveCell.Offset(1, 0).Select Loop Application.ScreenUpdating = True End Sub
I've got a rather involved macro that's running kind of slowly, and I would appreciate any help I can get speeding it up. It's in two parts; the first is to create and email a report, the second is to format so it's pretty for printing. The full codes for both routines is pasted below.
The email part I developed first and it runs pretty quickly. Afterwards, I added the second macro, which is called halfway through the first.
Stepping through the code in the second macro, the problem I see is in this section, the setup for setting the heighth of merged cells in the report:
I run a simple macro loop to clean some data across nine columns. The purpose is to collapse the data in the columns so that column 1 has the first value found in that row, for the set of columns. For instance, if columns 1-4 are empty, it deletes / shifts everything left until the first column is not empty. Then it goes to the next row and repeats. Data can range from a few rows up to 6000.
[I have a period in the data as the cell content to evaluate]
Sub A_Rollup_collapse() StartT = Now
Dim Col As Integer Col = Range("IV1").End(xlToLeft).Column - 9 LastR = Range("A60000").End(xlUp).Row
Application.ScreenUpdating = False For R = 2 To LastR Do While Cells(R, Col) = "." Cells(R, Col).Delete Shift:=xlShiftToLeft Loop Next R EndT = Now Application.ScreenUpdating = True
this macro (B) runs after another macro (A) that populates the nine columns with data using vlookups. Macro (A) It builds out a chain of information from col 2 to col 9, converts to values etc. Nothing odd.
When macro (B) is called right after running macro (A), it can take about one minute for 500 rows of data.
When I save and close the workbook, reopen it and run macro (B), it only takes one second.
When I insert a ThisWorkbook.Save between the two call statments, macro (B) still takes over a minute.
A minute is not too bad but when I'm dealing with thousands of rows, the difference is more like 30 seconds vs. 9 minutes which is a problem.
i am currently using the following code to copy records from one sheet to new sheets that that are created and named in the first part of the if(). this works fine, however when i am dealing with 50,000 records it still takes 5-10min to get them all sorted. I think this although functional is horribly inefficiant, and am wondering how i might be able to speed up the process. possibly rather than check each record, then copy then paste individually to sort them, then read and select the list of cells until value changes, then copy over at once. i dont know if this would be faster or not, let me know what you think.

I have recorded 7 different macros and then combined them all into one macro to achieve one end result. I am not sure if you can just look at the codes to determine different ways to improve them or if you need the excel spreadsheet as well.
Attached is a workbook that takes an imported text file, inserts rows with text.
It is SLOW, you can watch each line being inserted with the text, I would think with such a small sample dataset it would be much much quicker.
Information: See attached xls file.
On sheet1 is the imported data, sheet2 is a copy of the imported data so one can copy and paste to sheet1 as needed with out re-importing for test purposes and only for this query. (Sheets2 thru 3 are not used otherwise).
There is a command button on sheet one which will run macro "aaa". If you run this you will see how slow it is and exactly what it is doing.
I am simply looking for a way to speed this up, I have some files that are 10 times the size of the sample data and they take 10 or more minutes to run.
Im setting up a spreadsheet that does engineering calculations. Im using macros to run sizes from a standard schedule. It basically takes the values from one sheet (schedule) to another (calculation), then the result from the calculation sheet (Value only, not the link) is pasted back into the schedule. The macro seems very bulky and im sure that it can be made more efficient with a loop. here is a sample of the code from the macro;
I have a range of cells ( C2, C5, C8:N1007, P8:P1007 ....) on a worksheet that I want to be able to clear the contents of through a macro - worksheet is entitled Database
I have 3 additional worksheets all of which have summary information on and some of the formulas are huge.
I've inserted a module and produced this code;
Sub ClearContents() Application.Calculation = xlCalculationManual Range("C2, C5, C8:N1007, P8:P1007, ....").ClearContents Application.Calculation = xlCalculationAutomatic End Sub
Because of all the 3 summary page formulas the code is taking a few seconds to run.
I'm new to VBA and just wondered whether I could switch the calculation setting for the entire workbook onto manual at the beginning of the code and then switch it back to automatic at the end of the code? Think this might speed things up.
This used to (and on some machines still does) work very well, but all of the sudden on my work machine, it is incredably SLOW!! The whole program takes a list of tasks and dates, and creates a wall calendar from them. Then (the offending part, below in code) looks at each cell on the wall calendar and formats it by sizing the height of a merged cell so that the entire task is displayed, then goes on to put a square around it (works fine).
The formating of the cell height/width can take up to 11 SECONDS each cell. What is happening to do this? Again, it USED to, and on some machines still does, FLY through this process. But now it just crawls. Code below, with the 3 offending lines identified.
Private Sub Fit_Height(ByVal Target As Range) Dim NewRwHt As Single Dim cWdth As Single, MrgeWdth As Single Dim c As Range, cc As Range Dim ma As Range
Application. ScreenUpdating = False With Target If .MergeCells And .WrapText Then Set c = Target.Cells(1, 1) cWdth = c.ColumnWidth Set ma = c.MergeArea For Each cc In ma.Cells MrgeWdth = MrgeWdth + cc.ColumnWidth Next
An additional item (clue?) is that, after the macro is done running, it is still unbearably slow to do anything on-screen. Grabbing the column header and changing the column width takes 5 seconds or so before it snaps to the desired width and displays correctly. Closing Excel and reopening it takes care of that problem.
More advancement (as I wait). It seems to be the Application.PageSetup that kills it. As soon as I hit the first Application.PageSetup line, the app grinds to a halt, and almost every line after that that manipulates the screen format or the page format takes 5 or so seconds EACH to process. I put them all at the end, but that really doesn't solve the problem, nor explain it, nor give me a true solution.
I have a VBA Macro that loops through about 100,000 rows in an Excel file and removes rows that have a duplicate cell value. The macro takes about an hour and a half to run. Are there any ways to make the Macro run faster? Any ways in general to make VBA macros run faster?
