Change Workbook Names to standard names in VBA - excel

I am working with a pretty long VBA code in Excel that references multiple workbooks. The issue I have is that the name of each workbook changes each month to reflect the new month/date, which then requires me to update the code with the new workbook name in order for it to work. Further, the change in name is not always standard across each month.
Is there any way I can, for purposes of the VBA code, rename each workbook that the code uses some standard name so that I do not need to change it each time? I know I can just create a new variable, call it "book1" and change its definition to reflect the workbook's new name, but everyone who will use the macro does not know how to use VBA and thus cannot go in each month and just change the name of the variable. Ideally I want VBA to always recognize the file, regardless of its real name, as another name, one that I set and does not change. I'm thinking there is some "technical name" that is attached to each file that does not change which I can use?
I have toyed with the idea of using dialogue boxes so the user can input the new name of the files, and thus have the code change accordingly, but would like to avoid that if possible.
This may or may not be possible, but thank you for your help nonetheless!

2 possibilities:
You could put in an extra sheet in the workbook, and in this sheet define that the file name is correct. Any Excel-User should be able to keep that info up. You could of course then check - before running your Long VBA code - if the files exist.
If the file name for example is "filetobeused12_august2013" then you could search for the newest file that starts with "filetobeused12" and use this file in your code. This is the more complex approach for sure!
hope that helps,

Use the Same Excel VB Code In Multiple Workbooks Used by Multiple Users Without Having to Update Each Workbook

tl;dr: Is there a way to have multiple (10+) excel Macro workbooks run the same project from a single location so that if I need to fix a bug, I don't need to fix it in every single workbook?
Long version:
My company uses excel workbooks for engineering charts. Any changes are formatted as bold and highlighted gray. We then have a revision "table" at the bottom (I say "table" because it's just some merged cells - there doesn't seem to be a way to make a separate table that doesn't follow the column sizing for the rest of the workbook, but that's a question for another day).
When we do a new revision, we have to first clear any formatting from the previous revision, make our changes (and format them), then insert a row to the revision "table", then unformat the previous revision entry and reformat our new revision entry. Then, we export the workbook as a PDF which we name according to our print naming format. However, it is easy to make mistakes when doing this because the file name must be manually entered according to the format.
To make this process less tedious/error-prone, I wrote a VB macro program to automate the above steps, among other things. It works great, and will be implemented on our charts company wide.
However, I can only do so much testing on my own - there are bound to be things I missed or can do more efficiently (I'm an engineer, not a professional programmer). And we have dozens of engineering chart spreadsheets. If we implement this and then I discover I need to fix a bug or make an improvement to part of the program, I don't want to have to fix it in every single workbook - that would take way too long and be too easy to miss a workbook!
Any advice would be appreciated.

Dynamic Workbook Name changes and cell references - Is it possible?

my question is a pre-code question, as I would like to verify if and which is the best option to go about this - either formula, VBA or not possible.
I have a main workbook with an array of codes inside cells in sheet 1 - all in the format HXXX-XXX-XXX where X is numbers ranging from 0-9. Each code has an associated revision number as shown in the attached picture.
The workbook itself is named in the format: 'HXXX-XXX-XXX-YY Example Title' where YY can be any number starting from 0 to infinity (in theory). Only YY is subject to updates in the title. If changes are made in this workbook, then a new version is saved, with the YY changing in the title to the next consecutive number - Nothing else changes.
From this main workbook there are a large number of other workbooks (around 50) which share the same codes and revisions. My goal is to link all these workbooks up so that I only have to update a core main workbook and the rest of the codes (HXXX-XXX-XXX) revisions in all the other linked workbooks update accordingly.
The problem is that the other linked workbooks have a dynamic name in the format: 'HXXX-XXX-XXX-YY Example Title 2' where YY can be any number starting from 0 to infinity. YY gets updated to the next consecutive number if a change is made inside the document and this document is then saved as a separate document using Save As. NOTE: not all workbooks will get updated at the same time, as it all depends on which codes and therefore revisions are changing.
My question is firstly, is this possible with current excel functions to update links with ever-changing workbook links, which are saved as different files each time in the same folder?
Secondly, I have read about the INDIRECT function, but it is limited only to having the required workbooks opened at the same time as the updates to the main workbook, hence I am unsure that Formulas will work (I will be linking 50 workbooks to the main workbook) - From this I am gauging that VBA may be the best option, but I would like to double check this is possible before I begin attempting the code.
Of course the use of Formulas in the sheets would be much better, but because the file names are dynamic, and since the updated workbooks are saved as different files each time changes are made to it, I don't believe this is possible.
If I understand your problem correctly you need to differentiate between 3 things.
Using only Excel Formulas.
The problem with this is that formulas crossing workbooks have the big disadvantage, that you need to have the source-workbook open, otherwise manny formulas will not work correctly or update. You also have the disadvantage that saving the file needs still to be done automatically. The advantage is that you do not need VBA macros.
Using Power Query
With Power Query youmight be able to solve the problems with the dynamic names.You can even read a whole folder of files, combine them and do transformations without the need to open the files manually. But you still need to save new files manually and the files will only update once they are opened.
Using VBA
You can prettymuch do everything you asked in your problem description but VBA has its own disadvantages. Firstly the file-format ".xlsm" is not allowed by the IT department everywhere. Also to work, every user using the files needs to activate macros, otherwise the macros won't get executed. Therefore I think a VBA solution is better fitted if you only have a small circle of users or if you can execute the macros on your own (e.g. if the main workbook was updated, you need to execute a macro which opens, modifies and saves all affected files). After that you colleagues do not need VBA themself.
Possible solution:
To avoid VBA you could try to create a Power Query in each "other workbook". The query will read all filenames in the folder where the main workbook is located. Now you sort and filter for the workbook with the newest/highest ID/Titel automatically and load the result as an seperate Excel sheet (all that is possible with power query and without VBA).
Now you can use the "indirect" formula to use the ID/Titel to link to the newest main workbook. As mentioned above this will require that the main workbook is opened. Otherwise the indirect formula will not update the values. If that is out of the question, you probably need to go with VBA.

Is there a way to make a logbook in excel of files being created?

I want to make a dynamic excel sheet that updates whenever a file is being created into a folder, think of letters. So the sheet needs to extract the name of the letter, the date&time when it is made, the author and so on, into a table in excel. Does anyone knows how to get that filedata?
I already know how to put data in a certain cell using VBA but the thing i get stuck in is how to get that data from a certain folder.
As Ron said, there is no event in VBA to handle that. However, if you want to stick to VBA only, you have basically two options:
You can update your cell whenever the workbook is opened using the Workbook.Open event (https://learn.microsoft.com/en-us/office/vba/api/excel.workbook.open). This is not really dynamic but might be sufficient (depending on your needs).
Other option would be to call a function periodically to check if the folder content has changed (https://learn.microsoft.com/en-us/office/vba/api/excel.application.ontime)... Not very performant, but would work for sure.
For the file data just follow Ron's suggestion.
Hope that helps, MJ.

Dynamically reference cell in different workbook

I have two workbooks:
WorkbookToUpdate.xls
Workbook_for_20130901.xls
In the first workbook I have the following:
A1 ='[Workbook_for_20130901]Sheet1'!$C5
Now a month goes by and I want to update the first work to reference Workbook_for_20131001.xls without going cell by cell and changing the name of the workbook. My thought was to make the date portion of the workbook name a variable and simply change that variable, but that doesn't seem to be working.
EDIT: I don't want to use Excel's INDIRECT function because I don't want to open the reference workbook.
I found one solution to be Harlan Grove’s PULL function (code can be found here), which works similarly to the INDIRECT function except that it doesn't require the source workbook to be open. The other solution, which actually works out to be faster than the Pull function (its only downfall) is the one I was using originally - Good ol' "find & replace". I thought that that was slow, but after trying the Pull function, it's not too bad.
Another option is by changing the source through excel's Data links, but this doesn't allow you to choose which cells keep the old source and which cells use the new one (in my case, I need the old values as well).

Create a new sheet for each row

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?
