In short, I would either:
Create a macro that runs every time a cell within a certain range is changed, and then writing out the result based on those cells.
-OR-
Create a macro to automatically insert functions that would do the same thing
Things to consider are that this would need to work on multiple tables of varying length without need to manually change anything, and that the results of individual sheets would need to be also displayed in summary on another page.
Which would be more desirable/more efficient/easier to implement?
The subject data entails testing procedures. Sheets contain testing criteria and a column containing PASS/FAIL results. I need to tabulate these. The start of the table and the end of the table are at different rows and are subject to changing.
Without seeing your actual problem I would definitely go for the first option. Having many formulas inserted into cells dynamically I think would be a pain.
Use the Worksheet_Change event and test whether the cell changed is one of your target range, then perform whichever action is required.

I have a spreadsheet which will be used as a form by a number of users, and based on a few pull down boxes selection, a number of cells will change value (Independently of each other).
I have several macros which I want to run when the cells change (again independently, not collectively)
I already have one which runs using worksheet change by target value within the worksheet, but can't get anymore to work with this code.
A bit of a novice when it comes to this sort of stuff and need some help - using latest version of excel.
I have a large Excel spreadsheet and need to provide some automated sanity checks by selecting options from a couple of dropdown lists which have directly defined options i.e. in data validation values are entered directly instead of using a cell range.
I have tried writing a value to the cell but it is protected from direct writes.
I could add a cell range instead of directly defined values if need be.
Everything else works, opening the target spreadsheet, writing other values, reading back etc.
Thanks
Removing the protection worked.
The target spreadsheet takes a few seconds to perform calculations each time and I have not had to add any waits or status checks before reading the values back from other cells.
I have an App_SheetChange() handler in an add-in that does some processing as modify their spreadsheets.
I've already optimized the handler to only perform the processing if the user's update happens within the range that the processing is dependent on (only one column).
But when users delete rows or insert rows, I don't need my routine to run.
How can I somehow detect that the change that resulted in the call to App_SheetChange() was simply inserting/deleting a row, or in some other way ensure that inserting/deleting rows doesn't call App_SheetChange() in the first place (which seems a bit heavy-handed)?
One potentially-important caveat: the code has to live within the add-in, I can't add macro code to individual workbooks.
I can't think of any way to do it.
Maybe you could use a workaround, say, to check whether UsedRange, or CurrentRegion, or some named range lost a column/row since last App_SheetChange.
Or maybe, you could set the .ID of each cell in the column to the address of that same cell, and if on an App_SheetChange the Application.Intersect(your_column, Target).ID doesn't represent the actuall address of the Application.Intersect(your_column, Target), then a deletion (insertion) has happened, and instead of running your macro you should update the .ID property of each cell in the column again.
I'm trying to find a way to from a Cell get the data from a cell in the Sheet that lies to the Left (down in the tray) of the current Sheet.
I know how to call to other sheets via
=Sheet1!A1
But now I need something best explained with
=Sheet[-1]!A1
Any ideas?
Using the tab order as a fundamental part of your calculations is a complicated and risky approach to Excel calculations. Excel offers many alternatives which you'd be better off using:
A simplified version of belisarius's suggestion is: =INDIRECT(A1 & "!A2") where cell A1 has the name of your datasource sheet and A2 has the name of your target cell in your datasource sheet. If you know the name of your sheet of interest (or can look it up in some way), use this method.
If you need to do this often, you might want to export the data into an actual database (i.e. MS Access). Then you can make standard SQL queries and import the results into your Excel file.
If you absolutely want to go the VBA route, then you'd have to write some code that:
3a. Grabs all the names of the active workbook and stores them in an array.
3b. Identifies the index number of the currently active workbook in that array. Subtract 1 from that index to get the sheet to the left.
3c. Gets the cell value from that sheet.
You can also get freaky with Named Ranges. In Excel 2003, go to Insert->Name->Define, add a new Named Range and you can use that name in your calculations instead of referring to the cell by row and column.
Edit
The whole Idea with this one, is that
you have the Sheets arranged, and are
able to move them around, and that
shall change the calculations. – Gnutt

Please, please, don't do that. For starters, this isn't a standard method of interaction with a spreadsheet. Your end-users will likely be confused and may not even ask for clarification.
You'll want to explore the idea of data validation:
Using Data->Validation, make a drop-down menu listing all the sheets in the workbook (if the names of all the sheets are static, you can just hardcode them, otherwise, you'll need some VBA to pull them).
Then the user just picks the sheet of their choice and indirect() will automatically update everything.
Alternatively, you can also check out Tools->Scenarios. I don't know anybody who uses this feature, but you might be a good candidate for it. Basically, it lets you see the results of calculations using different datasets (i.e. "scenarios") so the user can go back and forth between them.
Using either of the 2 methods above, there's a good chance you can avoid VBA entirely, thus saving users that annoying warning message when they open your file.
=INDIRECT("Sheet"&TEXT(VALUE(MID(CELL("filename",A8),FIND("]",CELL("filename",A8))+1,256))-1,"#")&"!A1")
Caveats:
Your workbook must be saved previously
A8 may be replaced by a reference to ANY non-error cell
I know it's not seen here as good practice, but I want to do something similar. And it does replicate database functionality to an extent but I don't have the time or support to build one from scratch when there's something already half in place.
The reason I want to be able to do this is to create a summary table that links to all the worksheets in the workbook, and automatically extends if you insert a new worksheet. This is to manage a large sales / reporting spreadsheet with lots of different business units that all have the same structure (ie use the same worksheet format to report the same outcomes for different people. There is a high turnover. I want to have several summary sheets reporting different aspects of the source sheets. This is very time consuming to manage if recreating all of the tables each time.
You should be able to use the row() as an index marker to define the information that you want using something like REPLACE, OFFSET or INDEX but you can't as they only refer to 2D arrays.
Whereas Excel treats 3-D references as arrays for statistical functions it does not seem to do the same for reference functions. You might have SUM(sheetX:sheetY!A1) and be able to add a sheet in between, there is not (eg) a INDEX(sheetX:sheetY!A1,n) function. I've tried experimenting using these 2D functions as part of array formulas, and defining the 3D reference as an array or a named range... well it was worth a go :).
So I believe it's a valid action. I also believe there must be a way to do it, but for now I'm falling back on a UDF that has the risk of errors caused by calculation issues, or manipulating a Workbook_SheetChange function or similar. Or creating a single master sheet to control all the others which is populated by using a subroutine based on an array of all workbooks.
these functions work well for me. They get the worksheet index (the parent of
the range you call them with), add or subtract from that index, and then create
a range from that (relative) sheet and the address passed in.
Function relativeSheet(r As Range, iRelative As Integer)
Application.Volatile
relativeSheet = Sheets(r.Cells(1, 1).Parent.Index + iRelative).Range(r.Address)
End Function
Function prevSheet(r As Range)
prevSheet = relativeSheet(r, -1)
End Function
Function nextSheet(r As Range)
nextSheet = relativeSheet(r, 1)
End Function
In an Excel sheet, I have roughly 30 rows x 100 columns of data. Each row represents a different "client". For each client, I've create a summary sheet that is emailed to them and that also contains all the information from my main sheet
Is there a way for Excel to create a new sheet based on some template sheet when I add a new row to my main sheet and fill it with the appropriate data?
I will give you my opinion about your need, the way I see it, at least. It is not a "ready to use" solution, however, only some ideas about the way to do that.
From what I know, there is no way to track insertion of a row in Excel. So you would require a VBA function to be activated on a button, for example. Actually, there is, see Lunatik's answer.
This function would loop over all rows in your main sheet, and create a new sheet when necessary (you would need preferably a unique id for each client, it could be a simple index on the main sheet, depending on the line).
You would create at first your template sheet, with a specific name, and eventually hide it (to not have it in the visible tabs). When I say that the function would create, it would in fact copy this template sheet and give it a unique name (the id I mentioned earlier). You can find ways to copy sheets at this link.
A second operation to do, would be to put data from the row in the main sheet, to the template sheet (if I understood correctly your requirement), which is not really complicated to do in VBA.
If you need this to happen automatically on the addition of a row then you would need to use the Worksheet_Change event to capture the completion of a new row.
This would then generate a new workbook from the template, copy across the necessary ranges then save the new file somewhere, much as Gnoupi says
All this is relatively trivial with VBA, but unfortunately if you aren't familiar with VBA then isn't a simple case of "Do X then do Y in Excel" so I think you may struggle, even with sample code posted here.
Even if I created a dummy model that did what you require, functionally at least, then customising it to your particular needs may difficult if you are not used to working with Excel programmatically.
Edit
I've created a very simple demonstration of how this could work: http://drop.io/4clxof3 - note this example doesn't include the event handling for adding a new row, has almost no validation or error handling and makes sweeping assumptions about almost everything(!)
If you feel comfortable using this a basis for developing your own solution then great. If the whole VBA thing is foreign to you then it may be time to call in reinforcements :)
i was wondering if it was possible with no error catching. Simply just have a VBA code that takes each row of the Excel Document - Creates a file for each row and then at the end combines the total files in a folder into one?
I know sounds weird.. but is this possible?
