I have an Excel file that has a certain amount of Array Formulas. It takes 30 seconds to calculate every time the user makes a change. Some users do not have the Status Bar showing, and they think that Excel is "locked up". I want to make a user form that will appear when the Stats Bar is "Calculating..." There are a lot of "progress indicator" tutorials on this site, but they all seem to relate to VBA code being inserted in between certain lines. That doesn't apply. My Excel file has no VBA. It just takes a long time to recalculate. I want a VBA form to appear, that will match the % progress shown on the Status Bar, whenever a change is made to the spreadsheet.

I have a spread sheet that contains many user defined functions from a 3rd party provider that downloads financial data from an external database. Often not all of the data is required by the user, and as the UDF's take a long time to calcuate, i'd like to provide the ability to easily switch them on and off. Originally I had been looping through cells and either adding an apostrophe in front of the = or removing it. However running this loop is very slow.

I found this thread (Optimize VBA Loop For Inserting Formula) and adapted it to convert formula strings (with ' in front) to formulas in a single pass by setting:

myRange.formula = myRange.value. This works very well. I can't, however, work out how to go back the other way in a single pass. Have tried: myRange.formula = "'" & myRange.formula. This works for individual cells, but not for more than one at a time.

Where D3 is a starting date, E3 is a closing date, and A5 is a sorting code. It looks at my general journal and looks for all the entries between the two dates, and then sums up all the entries linked to the sorting code in A5. The sorting code is in column H, and the amount to sum is in column I, and this is repeated 3 times.

You are already probably signering at how long I must have to wait while excel calculates all these formulas (* 220). I have resorted to a macro that turns caluculation to manual when I open this workbook, and back to auto when it closes.

I am looking for ideas on how to speed-up one workbook. I have a spreadsheet with hundreds of lookup formulas and array formulas which are very slow to recalculate (takes around 5 min). Good thing about it is that these formulas are located in a specific range and that I need to run them only once a day (in the morning). Since I need to refresh the rest of the spreadsheet frequently, I am looking for an idea on how to isolate this resource heavy areas.

One solution I've been thinking about is moving these complex and slow formulas to VBA and run them only when needed. Can anybody assist me with the best and easiest way of doing this. Ideally I would want to leave option to the user to later edit this formula. Does anybody have any experience with weather it is best to migrate complete formulas to VBA or maybe leave formulas in the spreadsheet and run them based on predefined flag (that I can switch on or off from the code)?

I have a workbook with many lookups, sumproducts, dynamic named ranges and cse formulas. How do I determine what is causing my workbook to be slow? Are there more efficient formula types that I can use?

I'm working working with this spreadsheet that is moving incredibly slow. Every time I enter anything, it takes anywhere from 10 seconds, to a couple minutes to calculate and let me proceed. It is a pretty big file (4.60 MB), but I also work with another spreadsheet that is a little smaller (2.95 MB) that has never taken more than a fraction of a second to calculate anything. What could I do to spead up the spreadsheet?

I made one excel file with 9 sheet. there are used sumproduct formula in 200 rows.

i am not used any vba macro for this file.

i am used sumproduct formula link to other files and other sheets.

my file size is 1.80 mb but when i am enter new data in file then file going in process of calculation and calculate all forumula it take some time. my file options calculation is automatic but for calculation it take time and i have to wait for that for Process.

There are any macro for calculation so my file work fast and don't want to wait for calulation process .

This file is not open like other files. it is take a time in update the link or calculation.

I was wondering if is possible to replace SUMPRODUCT with code. Right now I have formulas like these throughout my sheet and I think they are causing it to be slow:

I also have the following code in my worksheet. I don't know if anything here is causing it to take so long to "calculate cells." Also my code just stopped coloring the row ranges and I not sure what cause it to stop working.

Private Sub Worksheet_Change(ByVal Target As Range) Const WS_RANGE As String = "O:O" If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then With Target 'Begin coloring row ranges based on these requirements If .Row > 3 Then If Me.Cells(.Row, "O").Value = "" Or Me.Cells(.Row, "O").Value = "O" Or Me.Cells(.Row, "O").Value = "H" Then Me.Cells(.Row, "A").Resize(, 26).Interior.ColorIndex = 0 End If.................

I want to say thanks for any help you might be able to offer. Attached are 2 sheets out of a workbook I am using which has many sumproduct formulas. On the the Input sheet, is where vacation and training forecast dates are listed. On the Calcs sheet, there are 2 monthly calendars for the year, 1 for vacation, the other for training. Would like to know if there is a way to have both records show up on only one calendar set. I currently have the vacation shown as a '1' and the training shown as a '9'. The workbook is used in Excel 2003 & 2007.

I am working with 4 seperate workbooks where 4 different people enter data into cells. I have a 5th workbook that needs to have all the data from the 4 individual workbooks bought across so I can see all data. Like a master file. basically, in each cell of the master, I have the following code. =IF('[loans - 0708 - officer 01.xls]07-08'!B5="","",'[loans - 0708 - officer 01.xls]07-08'!B5)

I then have the code for each officer. As there are 24000 lines collectively for the financial year, the size of my master is 37mb, even when its empty, obviously cause each cell still have a formular in it. Is there ANY way to copy across the data from other workbooks without having to have every single correpsonding cell have this kind of formular to view the code? Also, copy it without having to open the other workbooks.

Using Excel 2003, I'm summarizing info in one sheet (Review) with data in another worksheet (Work Orders). The following SUMPRODUCT calc worked fine...

I have this formula: =VLOOKUP(E24,OFFSET(Data!E$23,0,0,MATCH(TRUE,Data!E$23:INDEX(Data!E:E,MATCH(9.99999999999999E+307,Data!E:E))="",0)-1,14),14,0) in column e and looking up from a sheet called Data!. This formula looks up off of column e into the data worksheet from the point where I insert a blank row at a chosen point in the data. The problem is that this formula needs to calculate in excel where is shows in the bottom left of the screen...calculating 5%...50% etc. and I have to wait. Does anyone know how to rewrite this formula so it does not have to re-calculate after each move? This formula above requires a CTRL+****+ENTER.

What the formula above does is simply looks up into the other worksheet from column e and looks up only into the data where I insert a blank row. So it creates a lookup range at the point where the blank row is inserted.

I have an excel file which consist of 12 sheets. The main sheet contain columns from A to EL and 556 rows.

At the moment, i have data on from column A to AI (we will add more data day by day). All data in main sheet are linking to another 4 sheets which basically using IF, VLOOKUP, and Conditional Formatting. My file originally was only 4.6MB in size.

However, after adding the formula (IF & Vlookup) and conditional formatting to the fourth sheet (number of columns is from A to BZ) then the file size increased from 4.6MB to 13.7MB.

My excel file also became very slow and i need to take off the Automatically Calculation option.

I am doing a report which analyzes a specific person's transaction per country (3 criterias). The workbook has 3 sheets. First sheet is the database, 2nd is the report itself and 3rd is a reference table. I am using a sumproduct formula to count per person's transaction per country. It is giving me slow calculations.

I cannot possibly use a pivot table since there will still be other calculations involved after determining the transactions. I tried using database functions but i can't seem to understand how to go about it when there are multiple criterias involved.

The full formula is quite long as this pick up the data off over 300 work sheets. (there's probably an easier way to do this aswell) When I copy or drag this to another cell with on the same worksheet it gives me the correct formular with the correct cells changes as I want. However this formular does not work. I have auto calculate on and I manually press enter on the cells and still nothing. If I change the following for the entire formula (about 8min to do each cell) it works

I'm trying to condense a table of calculations down to a single array formula, but am getting stuck on one piece of it.

The table data is very simple, and can be in just two columns:

1, value 2, value 3, value 4, value 5, value

Where 1 thru 5 are time periods, and values are various numbers.

I want to perform the GammaDist function on each value. It requires a time period input, and in this case it is the 1 thru 5 in the table. So at the end of period 5, the formula for the first value would be

=Gammadist(5,x,y,TRUE) (x,y values not important here)

and the formula for the second value would be:

=Gammadist(4,x,y,TRUE)

The only thing that changes is the period number.

So, my goal is to write an array formula that will sum the GammaDist for each of the 5 rows, for all timeperiods (which is 5 in this case)

I can get this far:

={SUM(B1:B5*GAMMADIST(ROWS(1:5)-1,C1,C2,TRUE))}

But this passes 1 thru 5 to all rows, I only want 1 thru 5 passed to row 1, 1 to 4 passed to row 2, etc.

I am looking for a way to get a spreadsheet to automate calculations of unit costs based on variable packaging names.

I have a series of packages that are denoted by text phrases. Examples:

4/6/12 2/12/12 6/4/12 18/12 24/12

For our purposes let's say the package names above will always be in column A. Column B contains the frontline price of a case of product represented by the phrase in column A. Column C will contain the cost per unit of product - this is obtained by dividing column B by the number of each package arrangement that can be found in one case. Most of the time the number of package arrangements per case is denoted by the very first number in the package name (ie, 4/6/12 would be 4). This won't always be the case though (18/12 would be a package arrangement of 1).

I am looking for a way for the spreadsheet to do all of the following and return the results in column C: if the package name contains "4/6/12", divide column B by 4; if the package name contains "2/12/12", divide column B by 2; if the package name contains "6/4/12" divide column B by 6; if the package name contains "18/12", divide column B by 1; if the package name contains "24/12" divide column B by 24.

I want to find the Minimum Date of Seq "A" and of Asset type "Char". I used following Array Formulas but showing the correct answer 30-10-2008MIN(IF(A2:A9="A",C2:C9="Char"),(D2:D9)) But Istead of 03-11-2008 it's showing 30-10-2008 date of seq C and of asset type Prop

Do array formulas work if the array is across sheets instead of across columns or rows? I'm getting a #Ref! error when I try to use an "across sheets" array.

I have been lurking around for past month learning lots from MrExcel's wonderful web site. One of the many things I learned was how to improve my spreadsheets with Array Formulas, but today I ran into a problem on a new spreadsheet I'm building for work.

Here's the problem: I have 39 coworkers. For each coworker, I have 14 Array Formulas using SUMPRODUCT command with up to 5 "conditions", similar to this example:

{=SUMPRODUCT((user=$A$5)*(task=AO$3)*(DateChecked>0)*((Error="Error Removed")+(Error="Error Converted to an FYI")))}

Each condition such as "user" and "task" is a static named range of 5000 cells. This spreadsheet will hold one week's worth of my coworkers' work. This past week they have processed about 2500 items. To be safe, I doubled this number to determine the static named range size.

For each worker I have 56 columns (one for each possible task which a coworker can process).

So for each coworker, there will be 14 * 56 = 784 Array Formulas.

Currently my spreadsheet only has a single coworker defined, so I only have 784 Array Formulas, but it takes 35 seconds at 100% CPU Utilization when I press F9 (Calculate all formulas). Right now, I am running this on my Home PC (a 400 MHz PII PC with 256 Megs of RAM, OS is Win2000 at SP4 maint level and Excel 2002), but it is equally slow at work (1.7 GHz Celeron with 256 MB of RAM running Win2K SP4 and Excel 2K).

I haven't tested yet, but even if I assume a linear progression, with 39 coworkers I am thinking it is possible the amount of time for Excel to recalculate all the formulas will be 39 times longer than it is currently. This will be close to 22 minutes. That is a long time to wait! It will be even worse if my testing shows the amount of time Excel takes to evaluate the array formulas is exponential instead of linear...

I am having little luck creating an array to work with 3 critieria. Here is what I am trying to do: In the attached spreadsheet I am trying to show a total for each "Global Process" based on if "Reason Cancelled" and a date greater than or equal to March 1st, 2006. Here is what I currently have for the array formula: note: this is an Excel formula not VBA. I couldnt find the right code

Does anyone know how to activate a block of different array formulas at once??

Example:

N7:Q80 has a total of 296 Array Cells. Each has a unique formula & I cannot just drag to fill these nor can I activate all at once.

In the future, I don't want to have to manually activate them w/F2, CTRL+SHIFT+ENTER.

btw, Why do I have to press F2? Is that only in Excel 2007? I googled pretty extensively & don't see an option how to only press CTRL+SHIFT+ENTER. It would be nice not to have to press F2 everytime.

I would like to master the dreaded array formulas. Any Excel based accounting consolidation tool or other consolidation tool out there that I could adapt to consolidate group accounts on a monthly basis.

I would like to set up VBA codes to generate a variable number of transition matrices. I would like to know how I can define dynamic ranges instead of coding each and every range. In the codes below, I have to define each range one by one instead of using a loop.

Sub TransitionMatrix() Dim P1 As Range Set P1 = Cells(2, 2).Resize(3, 3) Dim P2 As Range Set P2 = P1.Offset(5, 0).Resize(3, 3) P2.Cells(0, 1) = "P2" For i = 1 To 3 For j = 1 To 3 P2.FormulaArray = "=MMULT(" & P1.Address & "," & P1.Address & ")" P2.BorderAround Weight:=xlMedium Next j Next i Dim P3 As Range Set P3 = P2.Offset(5, 0).Resize(3, 3)........................

I've created a very large spreadsheet (4096 calculations) and I'm using array formulas for a large number of cells, which leads me to my current predicament. All the formulas are written in, but I haven't done the necessary ctrl+shift+enter after finishing all of them (there is only slight variation in each calculation so I produced them in an iterative manner) and I was wondering if there was a way besides selecting each cell individually - pressing F2 - Then pressing CTRL + SHIFT + ENTER to make all my formulas array formulas.
