In our application in SAP we have a mail sending functionality. The problem is, its an old framework and it takes only 3 characters file types for attachments. We now want to send .xlsx files. But the framework only takes first 3 characters so it works with .xls. So when a user opens an attachment he gets the following message:
Now I know one solution is to go to Trust center and hide that kind of messages. The another framework that generates the .xlsx files can only generated .xlsx. But I can enhance it.
My question is: in the excel file structure (when extracted via 7zip) is there somewhere an information about what kind of file (filetype) is the file I just extracted?
Cause if the message in the excel is shown, I can imagine that there is a check that checks filetype of a file and some information in xml files in the excel file structure.
Thanks.

Based on knowledge gained through working with the OpenXML SDK, I have implemented an Excel generator in JS (using TypeScript with ReactJS and a custom JSX factory generating plain XML). The files generated open fine in Excel and one can also edit and save them fine in Excel, no errors.
However, if one tries to copy cells (even a single one) from such a generated Excel file to another worksheet in the same Excel instance, it fails with the error "The command cannot be used on multiple selections.". Just saving and reopening the file is enough to fix the problem. Copying to other applications (e.g. Notepad) works fine.
It seems that this particular error is shown by Excel in several edge cases where the data is not exactly meet the expected format, for instance I found reports of that happening when a sheet is hidden when manipulating it via VBA. However, in my case I'm not sure what could be causing the issue.
Just saving the file in Excel unfortunately significantly alters its parts, so that I couldn't get a meaningful diff out of it. I did not see what could be causing the problem. Maybe someone has some experience with the internals of Excel?
To get a sample file, copy the following into your browser address bar and save it as xlsx file:

Well, I don't know the particulars of how you are generating the xml file, but I can tell you how to edit the underlying xml files so that it will work, and then perhaps you can figure out how to use your implementation to change the property that's gunking things up.
First, an xlsx is a set of xml files. I'm sure you know that, but I'm just starting at the beginning. You can change the extension to zip and then extract the files, and then rezip them and change the extension back to xlsx.
So do this:
take the generated xlsx
change the extension to .zip
extract the files
find xl\worksheets\sheet1.xml
open it and find this property: worksheet>sheetViews>sheetView:tabSelected
set it to 0
save the file
go back to the unzipped folder
select all files and send to zip
change the extension on the new zip file to .xlsx
You should now be able to open the newly created xlsx, add a new sheet, and copy freely.
If this works for you, then you have diagnosed the problem, one property set to true when it shouldn't be, and it should be relatively simple for you to modify your export procedure.
I've had this issue multiple times in the past.
The way I solved it was by filling out (populating) a template (file, previously created in Office) with the exported data rather than generating a file from scratch. Office unfortunately does not fully comply with OpenXML, and for more complex exports you might even be unable to open the file.
I would also recommend Beyond Compare (now Scooter Software) for comparing the two files instead of just doing a diff.
I have done quite a bit of searching before posting this question so let me outline what I am trying to do.
1.) I do not want to use applications I have to download from a website or created custom commands (please no start Xls2Csv.exe here's a link to a website where you can download the program) I do not want to download a program to do this.
2.) I want to keep it in the batch file if possible - I have tried the vbc/vbs/vb files that is not what I am looking for.
3.) I found this an this is close to what I need but if I can stay within a batch file that would be best: Can a Batch File Tell a program to save a file as? (If so how)
Background
I have a bunch of test records stored in excel sheets within folders. Each test record has autoformatted name so the only real difference between any of the filenames is a serial number, otherwise each file name is formatted the exact same way.
I have written a batch file to search and find the files I need but I am stuck on obtaining a tiny bit of information in a .xls file.
What I am trying to do - I have excel files (.xls) and there is a word in a cell on one of many sheets that I would like to copy into a textfile. However I am unable to use findstr for an excel find because the command searches the file as if you opened it in notepad and the data I need is not present.
I am not concerned of data loss as long as I can get this tiny bit of information to a text file.
Otherwise what I have found to be the best solution is to convert an XLS to a CSV. I have manually done it by opening the file and saving as type .csv that worked.
What hasn't worked is:
example1.xls >> example2.csv
ren example1.xls example3.csv - this will save it as a csv file but still opens with the same formating of the xls file in both excel and notepad.
I was hoping that the was a command to recreate the manual process of opening the file and saving as csv.
If there are any other suggested solutions - maybe a command where I can search for a string within an excel file? That would be the simplest option.
We have a ms-excel xlsx file stored in SharePoint. This file can be edited in two ways: directly in SharePoint or through ms-access acting as a front-end of the xlsx file (as an external linked table). We want the xlsx file to be edited while the ms-access database is open.
While ms-access is open, the xlsx file appears as read-only. We want programmatically disable the read-only state, so that other people could edit the xlsx file while ms-access is open and, also, enable read-only again when necessary.
I think that the only way to get this is by sharing the xlsx file. My question is as follows:
I don't know whether the best way to share the xlsx file is using co-authoring or using the standard ms-excel sharing. We tried to do it manually using co-authoring, but the xlsx file could not be edited through ms-access.
If we manage to edit the xlsx file through ms-access, then, is it possible to change the shared status programmatically while ms-access is open throug VBA, .NET, VSTO, MS-Javascript API or any other language? I have searched in Google, but I have found nothing but some .NET library for ms-word (Microsoft.Office.Interop.Word.CoAuthoring), but, curiously, not for ms-excel and, as the great wise Confucius said, "if you search something in Google for more than three hours and you don't find it, this means that it doesn't exist".
But maybe someone has had this same odd problem and could help us.
Thanks in advance.
You can't. The first application to open the file will "hold" it, and the next will either could open it as read-only or not at all.
You may be able to let Access open the Excel file, import the data to a table, and then close the file. If the file already is opened in Excel, it may fail, and that you must, of course, take care of.
Another option could be to have a function in Excel that exports the data to another workbook, and then let Access read this.
I have VBA code that selects multiple PDF files in a user specified folder, parses through them, grabs specified data, and backfills it into a spreadsheet.
I have error handling for instances such as if the file is locked, but not for if the file is corrupt.
Within testing, the code actually manages to some how open the corrupted document and pull garbage, but I would like to just have a simple if statement that detects whether the file is corrupted or not.
Does anybody know if it is possible to check a non-excel file to see if it is corrupted using VBA?
My requirement is: I have been given an excel (the user uploads it to our server) and then my program should automatically add a macros code (defined in a text file maybe) to the excel file and then send it back to the user. I found a similar question but the solution only works in Windows but since our server is Linux based, I haven't found a way to do so.

Assuming you're being sent a file in xlsm format, you need to following capabilities:
Open the file as a zip file
Locate the .bin part path from the rels files - see Microsoft Open Packaging Conventions
Locate and open the VBA project's .bin stream
parse the .bin stream as a Compound Binary File Format file
Parse the binary streams that describe and list the module contents of the file, as documented in Office VBA File Format Structure
Add your module text as a new stream, and update the files from step 5 with the new contents.
It's not a small undertaking. The work has already been done in Python, and a lot of the libraries for working with zip files and compound binary format files are already in .NET for Windows. Otherwise, as far as I'm aware, there aren't any other pre-built tools, other than the tools from aspose
