# Omit Worksheet From Calculation

May 2, 2008
Broadly, my workbook contains 5 worksheets. Worksheets 1, 2 and 3 contain calculations, worksheet 4 contains a summary of calculations from worksheets 1, 2 and 3. Worksheet 5 is a data table used for worksheets 1, 2 and 3.

I need the worksheets to calculate in the following order:

1. Worksheets 1 and 2 extract data from worksheet 5.

2. Worksheet 4 captures that data.

3. Worksheet 3 uses the data from worksheet 4 and extracts data from worksheet 5.

4. worksheets 1 and 2 recalculate using the calculation from worksheet 3.

5. Worksheet 4 captures the refreshed data from worksheets 1 and 2.

Is there a way, using formulas in the worksheets, to ignore worksheet 3 on the first iteration of worksheets 1 and 2, and prevent recalculation on the second iteration of worksheet 1 and 2?

In my mind I can see Excel simply recalculating over and over again, or will it stop. Is there actually a "problem" here or am I perceiving something that will not occur?

I use VBA's WorkSheet_Calculate event to detect when a cell of particular interest calculates to a specified value. It works well as long as there is only one worksheet (tab). However, when I duplicate that tab (and the final app could have up to 10 copies) to run a different set of data concurrently, I get bad results. The data is online, real time trading data, with each selected stock being tracked in a different tab.

Apparently both (or all) tabs in the workbook react to the same event, whereas I would assume that the event routine in each tab would react only to a calculation in that tab. If this is in fact the case, is there a way to a) make the event routine in each tab respond only to a calculation in that tab, or b) upon a calc event anywhere, determine which tab it occurred in?

Here is the present event code; right now it reads exactly the same in every tab. As long as nothing is happening in any other tab, it does its job correctly.

I am trying to do is trigger an event when a cell changes, and this cell is updated via a linked drop-down box.

The issue is that the code seems to work fine (in about 10 seconds or less) if a manual calculation is entered into the sheet - but when it's done via the drop-down box, it takes about 3 minutes to complete the macro.

I have a workbook that has many simple functions moving data around to different sheets and processing some if statements on some of the data. The problem that I am running into is all of the data is initially pulled in from a SQL DB, and I believe that the workbook is calculating many of it's if statements, prior to all of the SQL data being loaded, therefore, many of the worksheet formulas are coming up with the wrong result. Is there a way to delay the calculation of all the basic worksheet functions, so that I can ensure that all the data is in the workbook from SQL, before they all fire. I have attempted to use Tools--Options--Calculation--Manual Calculation, but it appears that even though I have things set that way, all of the formulas in the workbook have already pulled their values through.

I have a rather large spreadsheet that takes a long time to calculate. One sheet has the data (about 2800 rows by 650 columns), with samples in rows and data for each sample in the columns. A second sheet has functions to group the data according to predefined patterns. That second spreadsheet is about 800 columns wide and as many rows as I need it to be, as the samples don't need to be analyzed all at once.

Ideally I would like to do all samples at once by making the second spreadsheet 2800 rows high, but the calculation time is just way too long. And there's the problem. The calculation time seems to increase exponentially with the number of rows I calculate at a time. I ran a few tests making it different sizes, and here are the results:

rows

time(seconds)

100

3.5

150

12

200

23

[Code]...

I tried both HLOOKUP and INDEX/MATCH functions and it didn't make a lot of difference. These numbers are for INDEX/MATCH.

Graphing these numbers show that it follows an exponential curve pretty closely. What is interesting is that the progress indicator at the bottom of the screen finishes in a few seconds, about 5 seconds for 350 rows, and I can see the new data after those few seconds. But then it sits and appears to do nothing for the rest of the time. So, for 350 rows, it looks to be done with the calculations within 5 seconds, but then it freezes for another 2 minutes with CPU usage maxed out before I can do anything with the program. That actual calculation time seems to scale linearly with the number of rows I calculate, but the time after it finishes calculating before it finishes whatever else it's doing scales exponentially.

The spreadsheet does have a macro and a couple of other sheets and a macro that do some later analysis and I wondered if that had something to do with it. To check that, I created a new spreadsheet and set it up the same as the original one, with the data in one spreadsheet and the INDEX/MATCH formulas in the other. I copied the data over, but setup the formulas new without copying/pasting anything. It didn't make any real difference.

Is there a way that I can set a single worksheet in a workbook to always be on manual calculation, but keep all other sheet in the workbook set to automatic?

I want to be able to open the workbook, any calculations to perform automatically and then i will select the 'manual' sheet and perform these calculations manually. I also need to these settings to always apply each time i open the workbook.

I have written a custom function to be called from worksheet cells. The function is basically a wrapper function for VLOOKUP on a single table. It makes cell formulas shorter, easier to read and self-documenting. Here's a much simplified version of the function:

I am using a simple =Right(A1,4) is there a way to change this so it looks in cell A1 and if the is character is a zero then only give me the 3 characters fromthe right?

so if A1 = sweden 2041 it would give me 2041

but if A1 = sweden 0411 it would give me 411.

I have workbooks in which summary tables are generated by lookup formulas. Tables are on different sheets but all use the same lookup value by referring to a cell on the 'master' sheet. The lookup value appears in cells on all sheets, by reference to the master sheet (e.g. [formula] = mastersheet!$B$2).

The master sheet contains the main summary table and is copied and detached for distribution, using a macro. For practical reasons, this is done in two stages, first copying the sheet within the workbook (to make minor alterations), then moving it to a new book to save and distribute.

This is where the problem arises. After the sheet has been detached, we find that if we now change the lookup value on the master sheet in the original file, the tables on that sheet will update normally, but the cells on other sheets remain frozen at the previous value and the tables on those sheets do not update.

The only way round the problem is by Shift + Ctrl + Alt + F9. (Maybe I should add that all my workbooks are always set to automatic calculation.)

The macro itself is not the cause of the problem; if we follow the same procedure manually, the result is the same. However, if we move the sheet in one step, eliminating the intermediate copying stage, the problem does not arise. But this is evading the problem, not solving it, and I would be reluctant to have to resort to this.

The original problem remains as stated, viz. failure of automatic calculation.

I have wind speeds and elevation data for 200 points. Each variable needs to go into a calculations spreadsheet on another worksheet. Once each variable gets put in the calculations automatically spit out the result. Now I need to use macro to automate this process so that it will repeat the steps I took for every line of data.

In English code terms, I want the Macro to say, take wind speed number and input in wind speed cell in calculations spreadsheet. Then take elevation number and input in calculations spreadsheet. Then take result number from calculations spreadsheet and input in cell. Then loop to go down the 200 lines of data. Is this possoble? Sorry for the non-technical wording.

I am using Excel 2003.

I have pulled various data points from a pivot table into a summary.

My pivot table is located on a tab entitled "Pivots - All".

My summary tab is entitled "Open Summary".

My chart tab is entitled "Open Charts".

The formula within the summary cell that is pulling from the pivot equals

=GETPIVOTDATA("Active Y/N",'Pivots - All'!$A$70,"Active Y/N","Yes","Leader","Eurich","Expected Tenure",4)

I have found ways to NOT display the zero values in the summary tab, but the column chart (which is set to use value as the data labels, continues to pull the zeroes in the chart.

Is there a way around this besides using the "clear all" within the summary? I refresh this data weekly and don't want to have to keep redirecting the cells in the summary to the pivot.

given code on this forum which created a "Search Box" on my spreadsheet.

The one thing that I would like to tweak however if that it finds the word/number that has been inputted in the search box itself (as well as finding the other genuine entries). Is there a way that I can search the whole sheet apart from cell C2 (The search box cell)?

Here is the existing

Private Sub Worksheet_Change(ByVal Target As Range)

Dim response

Dim c As Range

Dim more As Boolean

If Target.Count > 1 Then Exit Sub

If Target.Value = "" Then Exit Sub

If Target.Column = 4 And Target.Row 4 Then

Application.EnableEvents = False

Target.Value = UCase(Target.Value)

Application.EnableEvents = True

Exit Sub

End If

I'm working on a report for work in which I need to produce sevearl charts. For each of these charts I need to omit any values that are 0 or null. Since this report is going to be run several times a month and with different values it would be pointless for me to do it by hand.

In A3 is a surname, in B3 is a first name (and possibly multiple middle names, separated by a space). In C3 I'd like the first name ONLY and the surname

A3......................B3.................C3

Hobbs.................Jon Peter........Jon Hobbs

Peters.................Mark..............Mark Peters

Jones..................Bob Tim Mark...Bob Jones

In some cells the format (all in the same cell) is:

How to calculate the average of a set of numbers through excel formula when I want to ignore few skewed values. e.g. 1,3,2,5,90,2,4,56. I want to calculate average of the above set by ignoring the effect of two skewed numbers viz. 90 and 56.

I have a formula to calculate an average value for a reference range:

= SUMIF(DATA!B32:B61,"<># div/0")/MAX(1,COUNTIF(DATA!B32:B61,))

Because these cells are references the blanks are being treated as zeros so I am getting an inaccurate average value.

Is there a way to make it so it will treat blanks as blanks? I need the zeros to be zeros.

i need to lookup in a sheet for cells that start for example by "SE=", and copy them to another Sheet creating a list!

But some of this cells started by "SE =" are repeated, like:

SE = cars

SE = cars

SE = cars

SE = dogs

SE = dogs

SE = bike's

and this is what I'll need:

SE = cars

SE = dogs

SE = bike's

Is there a lookup function available that keeps the line breaks in from the lookup array? As shown in the example the Vlookup omits them, I have also tried with Index/Match, but its the same story.

I have a column that contains labels that are entered down to row 400. Below row 400 in the same column are formulas. If I do a filter on that column I get formula results in the filter list from the formula cells. Is there a way to omit the formula cells on the column that's being filtered? In other words, only list data in rows down to 400 in the filter list.

how much excel can do and the amount of experts that is willing to help out in this forum.

Is there anyway to combine all the values to omit redundant data?

For e.g.

A B

1 Apple 28

2 Pear 55

3 Orange 35

4 Pear 22

5 Pear 15

6 Orange 18

7 Apple 25

is there any VBA codings that could automatically reduced all the above data to

A B

1 Apple 53

2 Pear 92

3 Orange 53

I want to omit null values from monthly averages I'm calculating for some in consistent data. Currently, the macro I wrote reads the empty cells and I believe is viewing them as zeros. When taking the monthly averages, in some cases on parameter 'X' might be sampled for a particular date at a location, but another parameter 'Y' isn't sampled for whatever reason on that particular date at the location. Therefore, there is no value in the cell for parameter 'Y' for that particular date (the value is null). When the macro runs, it sees the blank cell for the particular missing date, but I believe it still views that as a 0 value which it includes in the average, instead of overlooking that cell b/c it is an unknown. So, for example, it might thinks there are actually six actual sampling results instead of five, and calculates the average based on six being the total instead of five which seems to misrepresent the average. (e.g., it's currently viewing 2, 2, Null, 2, 2, 2 as n=6 instead of n=5)

If possible, I'd like to keep the structure of the code as below with only the minimal modifications to address this issue.

I do have Options-->Window Options-->Zero Values de-selected....

I want to calculate a date that is 28 days in the future. I don't want to exclude any days - However - if the end date falls on a weekend or holiday, I would like to push it out to the next business day.

I currently have the weekends covered, but am stumped on the holidays.

(For weekends, I am using the WEEKDAY function on a hidden sheet, and then the following 3 IF statements:

IF today + 28 = Mon.-Fri., then give me today + 28.

IF today + 28 = Sat., then give me today + 30.

IF today + 28=Sun., then give me today + 29.

I have tried adding an additional IF statement to address a specific holiday - namely, President's Day on 2/18/08, which is a Monday - but it won't add the extra day, because I think my initial IF statement re: Monday being today + 28 is overriding it.

I'm using this formula to pick all rows from a huge range of cells "DATA" in another sheet, by matching the first column value (SAPDATA is the range that contains all the first column cells of DATA).

{=IF(ROW($B49)-ROW($B$48)>COUNTIF(SAPDATA,$D$4),"",INDEX(DATA,SMALL(IF(SAPDATA=$D$4,ROW(SAPDATA)),ROW($B49)-ROW($B$48)),2))}

All possible first column values have been stored as a dropdown in cell D4, and whenever I change the choice in the dropdown cell, the retrieval of those hundreds of rows takes ages in excel.

So, for example, transfer the data in column "A" below to column "C" below omitting any blanks when the formula automatically copies data over:
