why it takes about 100 times longer to set a value using a named range. The code below demonstrates the huge difference between Range("A1") and Range("my_range")
Public Sub testloop()
Dim counter As Long
Dim start As Double
start = Timer()
Im having slow performance reading a CSV file into 34000 sheet named ranges. Currently it takes about 8 minutes to read 34,000 records. After stepping through the code Ive realized there are two bottle necks.
1)finding which sheet that the range name resides see getRangeAddress() and
2) actually setting the value to the named range i.e. Range(ra) = dprecord(1)
The CSV file looks like this: <range name>,<data value> e.g. DPA_1001,99090
Performanace actually seem to slow as the macro runs.
Public Sub readDatapoints() 'Macro readDataPoints 'This macro will read in the a comma seperated value (CSV) file of datapoints.
Dim sFile As String Dim currentLine As String Dim delimit As String Dim counter As Integer Dim ra As String Dim fs As Object Dim ts As Object Dim dprecord Dim oldStatusBar As Boolean delimit = ","
I have a relatively small Excel workbook that is using numerous lookup and Match function combinations. I also have a number of dynamic ranges defined and a few UDFs.
Problem is I am encountering some fairly severe performance issues. Changing a single value on a sheet is taking ages.
I suspect it may be due to the workbook dynamic ranges recalculating. Is there a limit to the amount of dynamic ranges in a workbook? And when do they get recalculated? Could it be something to do with sequencing of the calculations?
I'm going to attach a file I'm working with so you can see my issue direction but here is the background:
- file you see is an excel export from another software. This is as clean as it gets.
- what I am trying to accomplish is take the data for each person listed and movie it to it's own sheet via a macro. Creating the sheet name based on the name of the person. I've completed that task before with some help here, but never with data formatted like this.
- does anyone have any options they can think of? I've tried working with the two cells that make up the page number and basicly the move off that but can't seem to get that to work.
- would anyone suggest any formatting changes (while keeping all data integrity) before trying a move?
In creating a chart that calculates home prices I need to be able to just enter "Good", "Fixer", "Remodeled", etc...and have that automatically use one of the numbers that I have set and add it to my total. I have created a box with variables for "Good", "Fixer", "Remodeled", etc...How do I make it so I can put any of those variables into the condition of the house row and make it add the dollar amount specified into the totals box? This is the very simple code that I am using to find the totals so far: =SUM(C5:J5)
Here's what I need:
Also, the plug in values in the first picture WILL CHANGE and I don't want to have to change the formula. So I need something to point to those cells.
I'm trying to write some code that is performing operations on large arrays, using a pair of For loops. In languages like C++ and Fortran, it makes a big difference to the performance of the code which way round you put these 2 For loops, due to the way that array data is stored in the computer memory. However, for VBA, I've no idea which way round this is. For an array, A(i,j), do I want
For i = 1 To N For j = 1 To M A(i,j) = Cells(j, i).Value Next j Next i
I have inherited an Excel workbook in which the formlas all contain cell names (and there are thousands of names in this book). I need to find a way to change from using cell names in a formula back to a standard absolute cell reference but have no idea how to do this?
I am trying to work out a % score for a telephone operator. To explain further, I would monitor a call that an agent takes. The agent starts at 100%. There are 20 points to be scored and they are scored like this
1 - Yes 0 - No left blank - n/a
B3 counts the number of entries in the column B2 counts the number of 1's in the column B28 = B2/B3
Seems to work fine until the agent makes a fail which would enter a 0 in the column. Somewhere I think I need to take account that there are 20 possible fails or passes?
For example key 20 has a min fee chargeable of 100, however a fee is chargable based on performance as follows:
Fee Range 10-9999 Fee Range 210000-19999 Fee Range 320000-29999 Fee Range 430000-99999999
So key 20 gets charged 0.1% of amounts between 0&9,999, 0.2% of amounts between 10,000&19,999, 0.3% on amounts between 20,000& 29,999 and 0.4% on the rest.
How can this be combined into a lookup/range/low-high formula to extract the correct values????
Morning all. I'm trying to use VBA to generate autoshape arrows to track changes in values.
Something allong the lines of Column B (Jans data) C (Febs Data) E (autoshape arrow, green up, for improvement, or red downwards for a worsening).
The problem I'm having is postioning my autoshapes. The only way I can do it at present is to keep all columns and rows a standard width, and position using multiples of those.
Is there anyway to set the autoshape to the cell height and width, and position it within the boundries of the cell? This way I don't have to worry about rewiting my code every time I change a cell width?
I am encountering a situation wherein each line of VBA code is essentially compiled as I type on that line, instead of when I move to a different line. For example, if the code I entered is incorrect, the compiler waits about half a second and then turns it red. Also, if I enter a space, it deletes it immediately.
I have thousands of rows of data sorted chronologically in a flat list. What I'm looking to do is have a pivot table or formula which picks out the highest value for a given person. Sound simple?
Okay, - column A: date - column B: name - column C: exercise weight - column D: exercise rep's - column E: exercise predicted max (essentially, weight x reps)
Now, I have a pivot table which picks out each persons highest "exercise predicted max" (right click on table, field settings, MAX) but I want to know the actual weight they've lifted and how many reps they've done with it.
So basically, I want a simple table which shows me the date, persons name, heaviest weight they've lifted and how many reps they did with it. I've used the CONCATENATE function to group the "exercise weight" and "exercise rep's" in to one cell but the pivot doesn't return any values (all cells in pivot = 0).
I have a list of employees who each have a performance rating (very top, consistent, etc). Each employee is also either above the midpoint of a salary range or below (which is represented by a separate column with 'Yes' for above and 'No' for below).
What I am trying to do is apply a separate set of %'s for each group of employees. So, for the employees who are below, I want to return 10% and 8% for each respective rating, but for those employees who are above, I want to return 8% and 6%. (for example).
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've a sheet that records performance on individuals, what it does is collate the performance daily on certain things.
Most are simple plus/minus one and i have control buttons that do this,what it does is: On click it adds one to a different sheet, or if to remove it minuses one, and there is a total box to sum these figures.
But there is also some provision to add collected money value, and what i would like to do is have a function that deletes the last figure added to the financial transactions This is the code If Target.Address = "$A$6" Then Sheets(2).Range("A65536").End(xlUp).Offset(1).Value = Target.Value
So for example in A6 £10.50 is added, but i can't think how i can provide a service that will delete the last figure in Sheet 2 range A, as this will be constantly changing.
I have built a fairly complex app in excel which takes 50 webqueries and makes a table out of specific data. It generally takes ~34 seconds to run through the webqueries, and when its done, it starts all over and runs the 50 queries again on 30 second delays. My problem is that for about 5-10 of these cycles, everything works fine, but after that, the time per set of queries starts going up...in the range of 2:00 or more for the same 50 webqueries that originally took ~34 seconds.
Without posting each of the userforms and modules, is there a general way to clear out the memory or see whats bogging down the process or anything between sets of queries to maintain performance? the webquery itself is a
With ActiveSheet.QueryTables.Add(Connection:= "string" & variable
statement that gets called each of the 50 times. The only thing I can think of is that somehow variables or some other procedure isnt clearing after each of the sets of 50 queries runs. Is there any way to check that or make sure it is cleared before it begins the 50 query set again? I noticed this mostly by watching my "physical memory avaliable" drop a small amount each time the set ran, and I had to quit excel before it would return to its original amount.
What I'm trying to do is show monthly performance based on products of a few different areas. Where I'm running into problems, is with the month listings. If the report shows one month at a time, I can get it to work with SUMIF formulas, however when there is more than one (and there will always be three).
I have a home finance spreadsheet that I've been using for a few years and in the last couple of days it's ground to a halt. Whenever I enter a value in a cell and hit [ENTER] there is a long delay with the spinning wait icon (Windows 7) and the Excel window reports "Not responding". Eventually (3-4 minutes) the update occurs and everything is fine.
The workbook has 9 sheets on it but only one summary sheet references the others. The sheet I'm updating has about 2200 rows, 50 columns and the formulas are simple A+B-C types. Performance DOES NOT improve if I change recalculation to manual. The only VBA is some macros to perform tasks and they don't execute dynamically. Adding comments and changing formats responds immediately, it is only updating values that exhibits the problem.
I've tried replacing all formulas with their values (paste special/values) across the sheet but again this didn't work.
Looking to create a system to measure KPI (key performance indicators). I need to include a weekly target and then measure performance for that week against the target. I want to create a form to make data entry simple, how best it would be to implement using excel. Would I have 2 tables, one for targets and one for performance and then use look ups, [URL]
I designed a spreadsheet which uses a lot of VLOOKUPs and it takes a very long time to recalculate. I don't know if there is another way I could do this, but this just seemed to make sense and it works just the way we want it but it just takes too long. Here is what the spreadsheet is designed to do:
We have data that is pasted into excel from another source. The data is broken up into account number, date, check number, and amount. Multiple payments from the same account can occur in one month so the data must be totaled. There is a custom function called concatif which works just like sum if but concatenates text. There are VLOOKUPs performed on the account number and the corresponding date, check number, and amount are inserted in the table.
I have a list of employees split out into gender and performance rating. I want to graph this to compare male to female salaries and performance. Data attached.
If I want to improve my excel performance like ability to open multiple excel and sheets to perform calculation, should I change to a SSD or a faster intel chip? My current PC sometimes give me a black screen for my excel sheet or is unable to save certain sheets when I open too many sheets.
I have in column B a link to raw data on another sheet within the same workbook that returns the same of a segment (ie "MSEC"). In column A I have SUMIF statements that total up the volume associated with each segment (ie "MSEC") that is shown in the report. Each SUMIF total is named (through Insert/Name) something that includes the segment name (ie "MSEC_TA"). In column V I want to offer a share number which shows the percentage of the total (ie "MSEC_TA) that each item is. So, I want a formula that allows me to say "E6/the text in B6 & "_TA". Since the text in B6 is "MSEC", that would give me the formula of E6/MSEC_TA, which is the named range which holds the total.
I'm trying to find a way to check if the first and last name that are the content of cell A are anywhere in cell B and beyond. I've included an example: http://tinypic.com/view.php?pic=28cpkr9&s=5. In the example A1 must match B1, C1 and C2.
Suppose that i have a table that displays different metrics for each month of the year. I'm dealing with waste management at a thrift store so I'm looking at the weight of donations salvaged, weight of donations sent to landfill and weight sold and so forth. It would look something like this..
weight sent to landfill weight sold
january 500 450
february 350 390
march 400 789
In my dashboard I'd like to be able to sum the total weight salvaged for certain months like Jan-Feb or Jan-March.
I've named the ranges such as "weightsalvaged.Jan_Feb". So for the sum of the weight salvaged, I have the formula =sum(weightsalvaged.Jan_Feb)
I would like to have another cell where I write "Mar" and the name of the range in the formula automatically changes from
=sum(weightsalvaged.Jan_Feb) TO =sum(weightsalvaged.Jan_Mar)
I inhereted a spreadsheet where the designer used range names for all formulas. i hate range names. is there any way i can delete all range names and have all formulas go back to showing cell references instead of range names? When i just go through and delete the range names, i get formula errors.
I have the following title = Application.WorksheetFunction.VLookup(Q, Range(QandA), 2, False) QandA is a range that is defined in the active workbook. The code excutes without error but TITLE does not get a value because QandA is reported as empty (when I position my cursor over it).
I have also tried:
title = Application.WorksheetFunction.VLookup(Q, Range("QandA"), 2, False)
In one workbook, i have a sheet with date like this:
TITLE Data......
TITLE2 Data2....
In each case, the Data is a block of cells of varying number of columns and rows. Each of the data blocks is a named range. When I reference the ranges from a separate workbook, the results from calling the range don't work at all (return #VALUE!) UNLESS the layout of the second workbook is the same as the source data! so for example, if range Data is in cells A2...F5, then i can reference that data ONLY if i put my formula in cell A2...F5 on the second workbook. this appears downright ridiculous to me and i'm hoping someone can tell me what i'm doing wrong!
