Skipping Blank Cells To Speed Up Loop?
May 14, 2014
I have a macro I run on thousands of rows of data which occasionally has incorrect line breaks that need to be brought up to the previous row. The macro works perfectly, however I'm trying to speed it up by skipping rows that do not need processing.
The macro inserts a check in column AQ to see if column A meets certain criteria. If it does not, "False" is entered in AQ, indicating the need for processing. As it runs now, the loop steps through each row of AQ to see if it needs further action.
I am trying to come up with a way for it to automatically just jump to "False" instances, skipping sometimes thousands of rows of blank cells that need no processing.

I was working on a project this morning (I actually got help here but this is more or less unrelated) and ran into a strange problem. It seems the For loop that I was using is skipping cells.
Was trying to figure out the problem using this macro and a list or random garbage.
Private Sub CommandButton1_Click()
Dim number As Integer
For Each Cell In Range("A2:A500")
number = WorksheetFunction.CountIf(Range("A:A"), Cell.Value)
Cell.Offset(0, 1).Value = number
If number > 1 Then
Cell.EntireRow.Delete
End If
number = 0
Next Cell
End Sub
Maybe someone who actually know something about programming can straighten me out.

creating a formula that will automatically bring the cursor to the next applicable cell. We have template wherein there are extra cells in between those that we fill out. What I wanted to happen is for the cursor to go directly to the next cell that I need to fill up.
Example would be that cell a1 is where we type the name then the next cell will be c1where we will put the addreas. How will I make the cursor jump to c1 when ive filled in a1.

I need to combined all non blank cells in a given row into 1 cell. But within each row i have 5 phases that the values fall into, which is denoted by the 1st charter 1, 2, 3, 4, or 5. for example, in a given row i have 1-a, 1-c, 2-d, and 1-f and these values occurs in non consecutive columns starting from G to ALR. I need a macro that sorts these values in one of the 5 phases. So in another sheet the macro would combined [1-a 1-c 1-f] in Phase 1 and [2-d] in phase 2. and if there are other phases it would put them in the appropriate cell.
See attached workbook : Work Order Summary Sheet.xlsx

However, in addition to what the macro already does, it is possible to add another work sheet in the same work book that outputs the values in separate cells? It also has to output the data in order: for example, in the first work sheet the data is inputted at random and has spaces but the macro will have to remove all the blank cells and output them in order based on the first value in the test string, 1, 2, 3, 4, and then 5;
input:
blank 3-x Blank 1-y blank 2-z 1-k
output:
1-k 1-x 2-z 3-y

I am using excel to analyze stock changes. Yahoo spits out a column with dates and another with closing prices but occasionally inserts a row showing a dividend, something like this:
Date Closing price
12/30/13 120
12/23/13 118
12/16/13 119
12/9/13 117
12/2/13 115
11/25/13 116
11/22/13 dividend 0.23
11/18/25 116
11/11/13 115
In the spreadsheet, column A is date and Column E is closing price, such that the cell in column E where the dividend is listed is blank.
The problem- as I update data each week, the dividend row moves. How can I consistently figure price changes for 4 weeks and 13 weeks without getting messed up by the dividend row? Is there to auto delete the row or make the formula count down 4 cells in the price column, while skipping any cells without data?

I required to do some Monte Carlo analysis for 1000000 simulation. I have managed to find some free code, however, the time it took to run 1000000 >30min. Is that normal? The code that it took the longest to run is following:
For i = 1 To number_of_trials
Application.Calculate
For j = 1 To number_of_formulas
runs(j, i) = sel. Cells(1, 1 + j)
Next j
Next i
Is there any way I can implove this code to make it run faster? I have already tried Application. ScreenUpdating = False

My sub is supposed to take the values from Sheet1 and paste them into 16x10 tables on Sheet2. However, for some odd reason, the loop is skipping some rows. If you take a look, there are 2184 values in Sheet1, but only 1368 end up in Sheet2...SKUs such as 518166,518167,510573,513746,513752 are just being skipped for no reason.

I have a large worksheet (Sheet1) containing approximately 15,000 records (15,000 rows x 21 columns). I need to search through all these records, and manually decide whether a record should be copied onto another worksheet (Sheet2) or not. The code I have written works very well (as far as I can tell), but it is extremely slow (the searching takes forever).
The code is as follows:
Sub SearchAndCopy()
Dim SearchRow As Long
Dim LastRow As Long
Dim SearchColumn As Long
Dim LastColumn As Long
Dim CopyToRow As Long
Dim SearchString As String
Dim Found As Boolean
Dim Response As Integer
On Error Goto Err_Execute
Found = False
'Fetch Search Term
Sheets("Sheet2").Select
SearchString = LCase( Range("F3").Text)......................

I have a problem with one of my loops, it takes about 17 seconds to do the job of calculating a simple moving average for 200 periods on 20,000 rows. However, if I do the "FillDown" function for the same type of average, it takes 1 second.
Here is the code for the loop:

I'm trying to write a VBA procedure that will loop through all the worksheets within my Excel workbook one by one (the number of worksheets in the workbook may vary from month to month) and count all the non-blank cells in Row 12.
If the number of non-blank cells is anything other than 24, I want the procedure to display an error message. (Each individual sheet in the workbook is supposed to contain 24 column headings, and all the column headings are in Row 12).

I am working in the attached spreadsheet. For anyone who does not wish to open the link, let's say these sheets are titled 'Sheet1' and 'Sheet2'.
Sheet2 looks like this:
Year Cat Name
2013 4 Sal
2013 4 Pat
2013 3 Pat
[Code]....
Now, how may I pull this data into a summary sheet (Sheet1) that skips over any instances where column A ("Year") is blank so it looks like this:
Year Cat Name
2013 4 Sal
2013 4 Pat
2013 3 Pat
2013 2 Pat
2013 5 Bob
[Code]...
Note: All columns are the EXACT same across each sheet(including Sheet1, Sheet2, Sheet3), if that extra piece of information works.
PS It is fine if, in order for a formula to work, I need to copy and paste the formula for the length of rows per each Sheet to consolidate.
EDIT:
So, in my industry, any summary-level data (shown on Sheet1) must have a linked reference to a particular sheet (Sheet2, Sheet3, etc.) so the user knows where the raw data came from. This is to ensure increased accuracy of data and minimize human error (like, if for example, I accidentally didn't copy and paste all the rows correctly).
I have uploaded the actual sheet to show what the data actually look like. I am trying to pull in 2013 data into my "Summary Page" and would like to have all the data linked to the '2013' sheet but skip any blank rows.
Here is my failed formula:
=INDEX('2013'!F$3:F$338,SMALL(IF('2013'!$E$3:$E$338<>"",ROW('2013'!$E$2:$E$338)-ROW('2013'!$E$2:$E$338)+1,ROWS(B$1:B1)),""))

I'm looking to easily drag the sum of certain cells in a different column BUT keeping a specific range, it's hard to explain so i'll show an example...
A1
A2
A3
A4
A5
A6
A7
A8
B1=SUM(A1:A4)
B2=SUM(A4:A7)
B3=SUM(A8:A11)
And so on...
Is there any way I can do this by dragging down the cell formula from B1 and it remembering the range of 4, so I don't have to manually select each range...?

I'm trying to total up some rows that are put in a repetitive order repeat. I can do this, but the method I'm using is highly inefficient. Is there some slick equation I don't know about?
Example below:
Worker 1 - Double Time - each of these has 200 columns for different job codes
Worker 1 - Over Time
Worker 1 - Regular Time
Worker 2 - Double Time
Worker 2 - Over Time
Worker 2 - Regular Time
Worker 3 - Double Time
Worker 3 - Over Time
Worker 3 - Regular Time
...and so on to 1000 workers
Total Double Time - for each job code
Total Over Time
Total Regular Time

I have this in Column A, with about 120 entries:
Company 1
Contact 1
Address 1
City, ST, ZIP 1
Phone 1
Fax 1
Company 2
Contact 2
Address 2
City, ST, ZIP 2
Phone 2
Fax 2
Company 3
Contact 3
Address 3
City, ST, ZIP 3
Phone 3
Fax 3
I want this:
Company 1 Address 1 City, ST, ZIP 1 Phone 1 Fax 1
Company 2 Address 2 City, ST, ZIP 2 Phone 2 Fax 2
Company 3 Address 3 City, ST, ZIP 3 Phone 3 Fax 3
all the way down.
I can't figure out how to record the macro to tell it to then skip the blank line, collect the next set of data, and put it in the next row. I can do it for two, but then it just replaces the first two with the next two and I lose data.

Attached is a sample spreadsheet. Please look at the spreadsheet will reading this post, as it would be rather confusing otherwise.
From this spreadsheet, I need to create two new spreadsheets (I assume one at a time is best). One (S1) will contain data from rows where Column C = "Regular Hours". The other (S2) will contain data from rows where Column C <> "Regular Hours".
The format of S1 (3 columns) is: Payroll # (Column B), code for the type of hour (this code I will need to write into the VBA code), the number of hours (D:G,Q:T,AD:AG), and the constant "N".
The format of S2 (4 columns) is: Payroll # (Column B), code for the type of expense (this code I will need to write into the VBA code), the dollar amount (I:P,V:AC, AI:AP), the project (Column C), and the constant "N".
The trick is each row on the new spreadsheets can only contain one hour/expense (otherwise this would be easy!). So, I need to loop to copy/paste the right cells, and need to skip over blanks, and need to end at column AP, then continue to the next appropriate row. As well, columns H, U, and AH are not used on the new sheets. I have another spreadsheet slightly similar to this with looping, but it is a delete type loop, not a creation one, and it doesn't have to have seperate rows like this does. I know this one is a bit big, but I know someone out there can figure out some looping code that can handle this.

My merged cells are not purely aesthetical - each merged cell (covering 6 rows in total, beginning at A3:A8) has colums and rows to the right for other details/formulae relating to that specific merged cell (which contains a customer account name).
The list I'm trying to reference is on a seperate tab - 'Projects' starting in cell A4. This list will have project names added to it, so I need my merged cells to reference the list, and subsequently pulling through all new additions to the list, rather than having to add them on a 2nd time.

Here are my cells and values
B38 C38 D38 E38 F38 G38 H38 i38 J38 k38 L38 M38 N38 O38
0.00

20.10

What I would like to do is average only every other cell AND also not count zeros. So =average(B38,D38,F38,J38,L38) generally the idea not averaging H38 & N38 since they are both zeros.

I am using Arrays throughout a large report and each time I move around in the report or simply open the report I have to wait 5 to 10 seconds to wait for the cells to calculate. Is there a way to prevent this from happening other than changing the calculation option to manual.
Is this and array problem? I don't get this when I use multiple vlookups and choose formulas? Any ideas to speed up or prevent all together?

I have a spreadsheet with temperature data, all in one column (D), that was recorded every 10 minutes for several months. In two adjacent columns (E & F), I would like to record the daily max and min temperatures. I can manually do this with MAX and MIN formulas in column E and F respectively, MAX(D1:D144). But when I copy this formula to the next row, I get MAX(D2:D145) when what I really want is MAX(D145:D288)....and so on...

I am looping through each cell in a range and I would like to loop in reverse order.
Dim CELL As range
Dim TotalRows As Long
TotalRows = Cells(Rows.Count, 1).End(xlUp).Row
For Each CELL In Range("C1", "C" & TotalRows)
CELL.Select
'Code here to delete a row based on criteria
Next
I have tried:
For Each CELL In Range("C" & TotalRows, "C1")
and it does not make a difference. I need to loop in reverse order since what I am doing in the loop is deleting a row. I am looking at a cell and determining its value. If the value is so much, then the row gets deleted. The problem is that the next row "moves up" one row (taking the pervious cell's address) and therefore the For Each Next loop thinks it has already looked at that row.

I have 2 columns of data E and F. Column E has 11 different words that randomly repeat, Column F has 10 years of dates, about 1,000 entries (10/11/12 format). Both columns values come from formulas.
I am trying to copy cells E & F to columns K & L starting in row 2 only if there is is data in column E (one of the 11 words) and skipping all others rows. Both the E & F values of tthe row must be copied together, i.e if text is in E45, then copy E45 and F45 into column K and L starting with K2 & L2. This is a task which will be repeated multiple times as data is replaced in columns A-D.
