Before I jump into a VBA solution, I wanted to know if it was possible to update a filename of a closed workbook I am referencing.
The formula reads,
=SUMIF('L:path\[filename - "&TEXT(WORKDAY(TODAY(),-1),"yyyymmdd")&".xlsx]Sheet'!$BF:$BF,"criteria",'L:path\[filename - "&TEXT(WORKDAY(TODAY(),-1),"yyyymmdd")&".xlsx]Sheet'!$DX:$DX)
To clarify, the path the filename would look something like this, This is the filename - yyyymmdd.xlsb
Someone at work said it's not possible to change the filename because it's a string. If that is the case could someone just expand on that a bit?
You can't really. If you have "Book1.xls" and "Book2.xls", what you can do it put this formula in book1:
=MID(CELL("filename",A1),FIND("[",CELL("filename",A1))+1,FIND("]", CELL("filename",A1))-FIND("[",CELL("filename",A1))-1)
This will return the name (only) of Book1. You could then reference that cell from Book2. HOwever, if you change Book1's name to something else, the reference will be broken and you will have to manually change the reference (pick the file from the update link manager). It seems excel uses absolute paths, including filename, to reference other workbook. You would need to have a way to store a flexible reference to that workbook into Book2. But the only way to do is VBA.
Interestingly however you can do that:
Create a reference in book2 pointing to a cell in book1. You get the value of that cell in book2.
Close everything.
Open only book1, edit the referenced cell. Close & save book1.
Book2, when you open it, will ask you if you want to update the link, and you can see the updated value even if book1 is still closed.
The other idea that I had was to use INDIRECT, like what is done there: using indirect function in Excel
But it won't work for closed workbook and that's one of your requirements.
So VBA it is.

I need some guidance in using openpyxl to manipulate inter-workbook cell references. Can anyone help or direct me to information about that?
I have several workbooks that contain cell references to each other (that I created using openpyxl). But these links are fragile when a workbook is used. I need something stable.
For example, two workbooks, wb1 and wb2, where wb1 has a sheet wb1_s1 and in cell A1 there is a reference to the other workbook
='C:\proj_py\builder\xl\[wb2.xlsx]wb2_s1'!A1
If I open wb1 Excel will ask me whether to update links. If I accept, I find that I can no longer read the original full cell reference, instead I read
='[1]wb2_s1'!A1
I find that this happens whether I open the workbook with Excel or LibreOffice. So, I suppose it is normal behaviour.
I looked at the underlying XML and I can see the =[1]wb2_s1'!A1 embedded after opening the file (and before that I can see the full refernce). What seems odd to me is that, as a user of Excel I can still see the full cell reference with the path to the file. However, it doesn't show up in the XML.
Is there any documentation on this sort of thing around? Can I create inter-workbook references in a different way that will not change?
Further info:
Watching what happens to the underlying XML, I can see the contents associated with the cell change. Before allowing Excel to update the link the XML is
<c r="A1"><f>'C:\builder\xl\[system.xlsx]wb2_s1'!A1</f><v></v></c>
and after it becomes
<c r="A1" t="str"><f>[1]wb2_s1'!A1</f><v>['my content in wb2']</v></c>
If in openpyxy I open the workbook with 'data_only' (as moken suggested), then the value of the cell is None. When I have opened with workbook and updated the links, the value becomes the contents refered to ('my content in wb2').
So, perhaps I can do not better than stipulate data_only (I must stay with openpyxl).
I have vlookups to pull specific data from a workbook and paste into a new workbook in the desired layout. The layout of the first workbook never changes however the name will change when i want to run this on a different file.
My current formula is =VLOOKUP(A3,[Workbook1.xlsx]Sheet1!$B$3:$XFD$7,2,FALSE)
I would really like it to reference A1 instead of Workbook1 so I could then just update the file name in A1 every time I want to analyse a different file. I should mention the Sheet name won't ever change.
I know you have to use INDIRECT but im unsure how it works. I did try =VLOOKUP(A3,INDIRECT(A1),$B$3:$XFD$7,2,FALSE) but then i'd too many arguments and when i removed the $B$3:$XFD$7 i lost the range i was searching in.
Thanks!
With INDIRECT you must create the whole string that denotes the range reference:
=VLOOKUP(A3,INDIRECT("'[" & A1 & "]Sheet1'!$B$3:$XFD$7"),2,FALSE)
One more note, that INDIRECT requires that the workbook be open to function, or will return an error.
I'm trying to create a dynamic reference within a formula; meaning the referenced workbook and subsequent sheet name can be changed and the appropriate data loaded.
I'm aware that a static formula reference could be done as follows:
=SUM('C:\Reports\[SOTDJ17.xlsx]Summary'!C10:C25)
but I want to be able to change the workbook name, and it will reference information from that particular workbook and change the data. The workbook name
is stored in B5 and the sheet is stored in B8. I thought I might be able to use
something simple like:
=SUM('C:\Reports\[B5]B8'!C10:C25)
but it doesn't seem to work. Is there a syntax error or something else I am missing?
(I should note that I am trying to reference a closed workbook)
You'll want to use Indirect():
=SUM(INDIRECT("["&B5&"]"&B8&"!$C$10:$C$25"))
Note that the workbook you're referring to must be open.
I have a Master workbook in MS Excel that references data in 4 other workbooks.
When it opens I get the following message:
We can't update some of the links in your workbook right now.
You can continue without updating their values, or edit the links you think are wrong.
[Continue] [Edit Links...]
Each referenced workbook contains a N row, 365 column rectangular range that I have named 'DataRange'
My master workbook contains 4 lots of N row, 365 column ranges with Array Formula linked to these named ranges:
{='C:\Path\[Workbook1Name.xlsx]Sheet'![DataRange]}
It feels like i've come across an Excel bug.. Anyone know what I'm doing wrong?
Are you using MS Excel 2013, when you receive this error?
If so, it maybe due to the "3D reference in your named DataRange" in Excel 2013 or because you're referencing a range or cell in a closed workbook.
Excel allows the defining of names that refer to specific cells or ranges of cells in that workbook, similarly (using the Define Name tool in the Formulas tab) you can assign a formula to a name and then use that name in place of the formula.
The named formula or named data range is part of a collection in that workbook's (workbook1) objects and can be used in different workbook (workbook2), but the link to the defined name in the other workbook must be done one of two ways.
Link the defined name with a formula like this
='C:\Folder\Path\Workbook1.xls'!NamedFormula or NamedDataRange
Or Create a defined name in workbook2 (it can have the same defined name as workbook1's or a new name) and then refer workbook2's defined name to workbook1's defined name. Select Define Name on the Formula tab and copy a link like this in the Refers To Field:
='C:\Folder\Path\Workbook1.xls'!NamedFormula or NamedDataRange
Note these links will only work when being used in simple formulas which treat the link as a direct links. It will not work with more complex formulas when the original workbook (workbook1) is closed because the link is often treated as an indirect link in complicated formulas.
To work around this issue, use either of the following methods:
Save workbook1 and workbook2 as .xlsb files.
Do not add an external reference link to a defined name that refers to a 3D reference or named range.
Or open both workbooks

If you're still receiving an error/ warning message after trying all my above suggestion. You might want to some troubleshooting.
Try this:
- Open Excel. Under Tools->Options->Calculation, select the Update remote
references box.
Open your workbook. Make sure the box the remote reference box is checked. Save your workbook this way after updating the link. Close workbook and Excel.Restart Excel and open your workbook.
- Look under defined names and delete all that you don't need or that have broken formulae. Run a FindLink search, to pin point the problem.
This process worked for one of workmates with this exact problem.
I hope this helps, if not let me know. There might be a 4th solution.
I finally solved this issue after going on a scavenger hunt. In my case, the reference was to an old file that no longer exists, and removing the reference was all that was needed. Unfortunately Excel does not pinpoint where the reference is, so it was a pain to look for the cell that was making the reference.
In my workbook, it was a reference as a part of a Data Validation. For others seeing the same error, I recommend using the Find & Select -> Go To Special feature (Home ribbon tab) then searching by Formula errors and and Data validation.
Open Excel
Go to "Inquire" tab page in the ribbon
Select "Workbook Analysis"
Check Items\Cells\With Validation Criteria items. In the "Validation Text" you might spot references to the extenal source.
The "Cell Address" column would give you the list of problematic cells.
Look around any other supsicious findings of the Workbook Analysis tool
Have you considered giving the data ranges different names? DataRange1, DataRange2 etc, or is this not possible due to other constraints. When excel says "some" of the links, how far has it got?
I got it working by ditching the FormulaArray and set the FormulaR1C1 for the entire range. Unfortunately the formula was a bit more complicated.
=INDEX(
'C:\Path\Workbook1Name.xlsx'!DataRange,
ROW() - ROW(Workbook1DataRange) + ROW('C:\Path\Workbook1Name.xlsx'!DataRange) - 5,
COLUMN() - COLUMN('C:\Path\Workbook1Name.xlsx'!DataRange) + 1)
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).
