I have two spreadsheets 1 of which gathers data on individuals for a daily basis for the duration of 1 month via a database query. The other sources this data (not via a lookup) for 20 staff members of staff and details this in a report. The report allows staff members names to change and automatically update their information from the previous sheet.
My problem is that even though the file size is 694kb when asked to update the sheet takes an age to load. Is there anything I can do with my sheet?
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 a rather large spreadsheet that takes a very long time to calculate once the new data is added. One of the many things I need to do is look to see if a unique value in range 1 is also in range 2. If it is, return some data (vlookup), if it's not, then I want a "0", not #NA. My question is, which of these two methods will result in a faster calculation (if at all):
Option 1: Do it in one step =IF(ISNA(VLOOKUP($A3,LY,3,FALSE)),0,VLOOKUP($A3,LY,3,FALSE))
Or option 2: Do it in two steps: Column N formula: =VLOOKUP($A3,LY,3,FALSE)
Column N+1 formula: =IF(ISNA(Column N value),0,=column N value)
I have many columns of data using formulas in option 1, so if I have coded this badly that could be my problem...
I have 40000 rows filling with data from column a to g, autofilter is alway on on said columns , the problem is that when I select any column to filter data as per my query , it takes long time to display result and sometimes it hangs with the msg xyz workbook is not responding.
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.
My current task is to create a spreadsheet that will auto-hide/show rows based upon values in other cells. I am currently about halfway 40% complete with this aspect of the file. I've read over many forums, and the best what that I've seen individuals do it on other sample spreadsheets posted were a =Rand() in a random cell somewhere in the sheet, and a Private Sub worksheet_calculate(). I'm far from a VBA expert. I'm trying to learn as I go along. Here is my current VBA:
I've created a bit of a monster Excel model taking in an enormous range of inputs and outputs. Most of the formulas are vlookups and sumif's. The workbook is now about 15meg. I've got autocalculate turned off because of the great deal of time it takes to recalculate. When I do try and re-calc some of the cells update but very many of them do not change at all. If I then go into these cells and edit them (F2 enter) the correct output is given! If I close the book and re-open it normally shows the correct outputs, after a while it goes back to the error above.
Let's say that in column A I have numbers,"Yes" and "No". I want in column B to have only the numbers from column A, in the same order without any empty ranges, and everytime I add in column A a new number, column B to update automatically with that number. Let's have an example:
A B Yes 12 12 13 No 10 13 No 10 Yes
And if I want to add in column A: A B Yes 12 12 13 No 10 13 25 No 15 10 Yes 25 15
So the column be will update automatically. I already tried =IFERROR(INDEX($A$1:$A$10,SMALL(IF(ISNUMBER($A$1:$A$10),ROW($A$1:$A$10)),ROWS(B$1:B1))-ROW($A$1)+1),") but using this many times get's my file very heavy and the excel is working slow.
I have some VB code which sequentially opens over 200 workbooks to extract data from each and populate another workbook. These workbooks do have links to other workbooks in them. For some reason when some of these workbooks are opened I get a requestor window asking whether I want to Update or Don't Update the data. I always want to Update the workbook and believe this can be done in VB by hiding the requestor?
I have a vlookup to another workbook. It works fine if both workbooks are open. But if both are not open and I open the workbook with the links and click Update, #VALUE! returns. I have attached the two files. I don't think it is my formula, but here it is anyway. =IF( COUNTIF([Tempozgrid.xls]June!$A$52:$A$83,A3),VLOOKUP(A3,[Tempozgrid.xls]June!$A$52:$L$82,12,FALSE),0)
which then compares the three-letter code with a list in the following format to create a new text file where data is only included if the code is on the list. Since I added the range search to the code it runs VERY slow
I'm working on a financial reporting project that should be in Access but unfortunately it must be in Excel. Some of the formula are complex and I have a UDF to calculate these values. I added the line
Application.Volatile
to each UDF but when I change the current month in a dropdown box, the UDF's do not recalculate. The dropdown box sets a period number on one of the worksheets - this same value is passed to each UDF. I tried using this code in my dropdown box :
Sub DropDown4_Change()
Application.CalculateFull
End Sub but the PC just hangs. I have hundreds (more likely thousands) of formula in the spreadsheet and the recalc is recalcing everything whereas I just want it to recalc the UDF's. I even changed all of the sumproduct formulae to array sum if formulae which sped things up - that is until I forced the full recalc on the drop down change event.
So my question is: is it possible to just recalc the UDF's on 3 worksheets when the user selects a different period in a dropdown box?
And a supplementary question : if {sum(if(...))} formula are faster than sumproduct formula, would a (well written) UDF perform faster than a {sum(if(...))} formula?
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
I have a time (1:08:31) that it took to travel 35km. How can I calculate the average speed of this competitors plus a number of others who recorded faster or slower time?
I managed to convert the time to seconds but when I load a simple formula to convert to KPH it never works.
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.
1) Current Speed 2) Current Acceleration 3) Acceleration Growth
Assuming: Current Speed=0 Current Acceleration = 0.2 (each 'turn' the current speed will increase by this much) Acceleration Growth = 0.2 (each 'turn', the current acceleration will grow by this much)
This gives a current speed over a series of 'turns' as 0.0 + 0.2 = 0.2 0.2 + 0.4 = 0.6 0.6 + 0.8 = 1.4 1.4 + 1.0 = 2.4 2.4 + 1.2 = 3.6 3.6 + 1.4 = 5.0 5.0 + 1.6 = 6.6 6.6 + 1.8 = 8.4 8.4 + 2.0 = 10.4 etc.
What I'd like to do is have a formula (or some way other than calculating each step) to tell me how many turns it would take for the Current Speed to =>X (example 100)
Basically, Turns to X speed = something clever * acceleration growth * something else very clever.
I have a Frame on a UserForm. The Width of the frame depends on values given in TextBox.Dat1 and TextBox.Dat2.
Now I tried it with a width of 2200 with a scroll bar, but when I change the value in the Textboxes I need the Frame to be cleared. Now this is my question. I use "UserForm1.Frame1.Clear" but this can take up to 1 minute.
I'm trying to automate a process where I get a list of checks and money orders purchased then manipulate it to make auditors happy. I need to eliminate all transactions less than $3000. The fly in the ointment, however, is NOT to eliminate daily transactions by the same purchaser that may be less than $3000, but when added together are greater than $3000.
I've created a helper column where I've inserted the formula ....
i hv a excel file which have 200k row. recently i learn from this forum using VBA (excel macro code) for select some data for analysis. it take very long. any suggestion will be apprecaited.
i already increase my note book ram to 2GB. it still slow.
The formula: ={IF(AND(ISNUMBER($A3);($A3-DAY($A3)+1)=F$2);$D3;IF(AND(F$2 > ($B3-DAY($B3));F$2 < DATE(YEAR($C3);MONTH($C3)+1;0));$D3/DATEDIF($B3-DAY($B3);DATE(YEAR($C3);MONTH($C3)+1;1);"m");0))}
I need to use this formula for over more than 30.000 rows and more than 50 columns. Is it possible to speed up the formula? Or maybe to handle this by a macro?
I currently have a macro set up to delete rows if a certain user selected value is not found in a certain column. It works fine if the sheet isn't overly large but the problem is we have some spreadsheets with 25,000+ rows and it takes time to loop through - I'm not sure if there is even a way to make it faster.
Currently it works by looping backwards on the sheet checking each value in the cell versus an array containing the user selected values. If a match isnt found it deletes this row.
'y = long value representing row 'x = counter for each item in user selected array 'wsSheet = worksheet we are using 'rowLast = last row on spreadsheet 'arrSearch() = string containing user selected items
i have screenupdating/calculations/events turned off - i just didnt know if there was a faster way of looping through
i just thought about instead of doing an array maybe joining the array into 1 string and using a "like" comparison check to see if a match is found - would save me from having to constantly loop x * y amount of times - not sure if this would work or not. ill post back if it doesn't
