Removing Blank Cells In A Large Matrix
Jun 12, 2009
This is my first post on this forum and I am an Excel novice. I have a worksheet with lots of blank cells and I need to shift all the cells with data all the way to the left (to column A). I cannot get the sort or filter functions to do this for me, and I've never used macros but it appears they might be useful for my problem. I'd like to find an automatic process to move the data left rather than drag and drop hundreds of times. I'm attaching the complete xls file for your viewing.

Using VBA, I wish to work out the inverse matrix of a large matrix (100*100), but keep getting the # Num! Error. I am using the minverse function. I have defined variable as "variant", does this give me the same possiblities in terms of number size as the variable "Double"?

I have a lists of e-mail address (up to 15 rows long) in adjacent columns.
At times one or more addresses need to be removed. After removal I need the list to 'bunch up' so that the space caused by the now blank cell is removed.
At the moment I am doing this with vba as follows:
Sub Clear_Blanks()
With Range("e13:e27")
. AutoFilter
.AutoFilter Field:=1, Criteria1:="<>"
.Copy Range("e35")
.AutoFilter
.ClearContents
End With
Range("e35:e49").Cut Range("e13")
End Sub...

How do I shift all the cells up labelled data, so that there are no blank rows in between? I tried using the ones found on the forum via search but it is stuck in an infinite loop.

I'm compiling several old worksheets into a single database for a research study. The worksheets contain patient data. Some of the worksheets have the patient's last name, first name, and middle initial entered all in one cell like this: Smith,John R. Compounding the problem is the fact that sometimes the name is entered with a space between the comma and the first name, sometimes not.
I have formulas to break the name out into three separate columns "lName, "fName", "midInit". However, if the name in the original cell has a space between the coma and the first name, then the “fname” column will contain a blank space in front of the name. This is problem because patients names can appear in the database more than once. Some patients are in the database several times.
If patient “John R. Smith”, for example, is entered in the database as”
“Smith” “John” “R “
and also as
“Smith” “<space>John” “R”
then the database won’t recognize them as the same name when I search for John Smith’s data. Right?
If so, then I need a way to eliminate the empty spaces in front of the first names. Like I said, some have empty spaces and some don’t. I could do this by hand, but there are over 1000 entries in these worksheets.

I am looking to remove all blanks from a table I have and move all the data left. Right now the data is by date, and some dates are blank for some players (it is a basketball sheet) and filled for others, but I want to see it by game. So I have what is in the first table below, and I want it to look like what is in the second.

I have a long list of values in column F of my worksheet. These values appear in random rows for example: cell F3 is 27, cell F9 is 7, cell F13 is 27, cell F20 is 9 ... The data is not evenly spaced any specific number of rows apart, but there are spaces (rows which are blank in column F).
I would like to put all of these values in column G but without any blank cells, and keep the order the same as well. So using the above example, Id like a way to make cell G1 read 27, G2 read 7, G3 read 27, G4 read 9.
Column F could be a very long column im not sure exactly how long as the data is being put in periodically. Some sort of formula that I could just drag down that would read the values from column F and put them in column G with no places would be ideal.

I am trying to calculate a matrix of array formulas that is roughly 365 x 137, or about 50,000 cells being calculated from a range of roughly 12,000 x 137. There are multiple if statements within the array formula, and then those 50,000 cells are referenced to another, but smaller matrix of array formulas (25 x 137). Each of these matrix sets is for one year, and there are three years that need calculated.
Problem: When calculating the 50,000 cells it takes roughly 2.5 hours to complete all calculations. So, for 3 years it will take roughly one work day of tying up my computer to just compile data that will then require several days of calculation/manipulation.
Question(s): Is there a way to speed this up to a reasonable amount of time (I'd even take 30 minutes at this point)? Or, is Excel simply the wrong tool to be using for this amount of data? Do I need a better machine to run these calculations? I am currently using a Dell XT3 with 2.5 Ghz i5 quad core processor.

Lets say I have a column, and i have some dates in that column. between each date entry are blank cells, an undetermined ammount.
ie:
------------
column1
------------
(blank)
1/1/2007
(blank)
(blank)
(blank)
2/5/2007
(blank)
(blank)
3/7/2007
(blank)
... etc ...
I would like some type of array formula, that could
agegrate that whole column into a new column, removing the blank cells.
so the new column would be:
--------
Column2
--------
1/1/2007
2/5/2007
3/7/2007
I was thinking something like... but this doesnt get rid of the blanks...
(this is using google spreadsheet, but ARRAYFORMULA, is the same as hitting "CTRL-ENTER" - in excel.
=ARRAYFORMULA(if(isnumber(A9:A17),A9:A17,0))

I have a spreadsheet which is used by users unfamiliar with Excel. They are using the filter to select records, however when this is used some records appear which have no entry in the cells of that column. Can I overcome this? There is no data in the blank cells, other than a data validation drop down.

I have Main worksheet (sheet 9) and some codes in Sheet 10 which I use as a source for data validation in Sheet 9. So far I have a macro which looks for changes in cells and, when someone chooses a code from the list the macro adds a comment to the cell and populates it with an explanation of the code. The explanations are also in the code worksheet (Sheet 10). It works really nicely but I cannot work out how to remove the comment if the user clears the value in the cell.
My Macro thus far is:

I have a texfile that populates a textbox on a userform. I would like to remove all blank lines in the string including those at the end if they exist, before populating the textbox. I'm reading the entire file at once into the string, not line by line.
Is there any way to edit the string called Text to remove the blank lines before populating the textbox? I'm looking for 2 carriage return characters in a row, and if so then remove one of them, but I don't know how to code that. This is in the userform activate section. If I read the textfile line by line, I don't know how to populate the textbox that way and remove the blank lines.

I have a workbook containing several worksheets. I use one worksheet to collate information from the others. I do this by referencing the relevant cells I need from the other worksheets with the '=' command.
When this displays it shows as a '0' if the original cell is blank. Is it possible for this to show as a blank unless there is any data. I have tried the ISERROR function but it still leaves the entry as a '0'.

I have to download a report through SAP and have written some pretty basic stuff to automate the formatting process, however, i still have to manually remove blank rows. I would like to be able to add the removal of theses rows as part of the code, one of the main problems that i see is that i run this report every week and the empty rows are not necessarilly in the order every time.

So in Cell K12 there is a rather large formula (I condensed it for this example).
This formula is to average out the respective cells in column J. For each cell there is a possibility of 9 different entries. NRT, N/O, 1,2,3,4,5,6,7
So based on the formula in K12 I need Cell J12 to Display the answer.
if any one of the Cells referenced in the formula are NRT then I need it to Display NRT. Which the Formula does now.
The problem comes in when a Cell is N/O (Not Observed)
How do I get the formula to Ignore N/O currently I have it set up to recognize N/O as 0. But excel averages 0 in and it affects the answer.
I know in a simple formula I can add <>0 to the formula to ignore zeros. How to write it into a bigger formula such as in K12.
For example the current numbers in Cells J17:J25 should average 5 however the formula averages it as 1 because it calculates N/O as 0.

The following macro deletes blank rows in my project (I have a source sheet that I "transfer" information to various "law practice worksheets", and it works fine. However, once I get past a certain number of rows (my project will include 65,000 rows), the macro does not delete the blank rows any more from the "law practice worksheets" (I previously sent this spreadsheet to the Forum with another question that was not answered yet). Here is the macro for deleting rows:
On Error Resume Next
Sheets("InternatlLaw").Select
Range("A2:D65000).Select
Application.DeleteBlankRows = True
Selection.EntireRow.SpecialCells(xlBlanks).EntireRow.Delete
ActiveSheet.Range("A2:D65000").Select
On Error GoTo 0.............

In VBA I'm trying to grab numbers from a cell range (ie: A1:A10), and save them to a matrix or variable. I will later need to grab additional numbers and add it to that matrix. I have experimented several different ways, but belows demonstrates what I'm trying to do:
VB:
my_data = Range("A1:A10").Value
my_data = my_data&Range("B1:B10").Value

I have one sheet that is used to check off when certain questions are answered for an inspection of departments in a building. As the first image shows, Row 1 contains the questions; Column A contains the departments. I simplified this for the image, but the rows represent individual audits, over time, so a department will appear again and again on subsequent rows, as new audits are conducted. When it's time to do a new audit, the user starts a new row and selects the department in Column A from a drop down list (via data validation).
What I need to happen is when the user selects a department, certain cells under each question are filled with black, indicating that the question does not apply to that department.

I have a spreadsheet with issue impact analyses tracked. I would have the Probability and Impact in two different columns with values ranging from 1 to 5. Each item has a reference number in Col A.
I have this matrix denoted in the file attached with Probability on the X axis and Impact on the Y axis as denoted in the image attached. you may note I have total of 9 cells in each block that represents different values of Impact for every value of Probability. Now I need to copy the reference numbers in the matrix presented at the bottom of the image in such a way that all the reference numbers with Probability 1 and varying Impact score will be sequnetially pasted in the cells of the squares with Probability 1 and Impact 1 to 5 (bottom most square blocks in the graph.
