Ok I have a excel template file which contains various headers, images etc.
I need to populate a number of excel files based on this template file using Microsoft.Office.Interop.Excel
I have seen plenty of examples online how to create and modify existing excel files (both xlt and xls) however none show how to create the xls from an xlt.
The only way I can see round the problem is to open the xlt, populate the data on the workbook then save the file as an xls....
Is this the only way that this can be done?
Thanks
Instead of using xlt and xls files you can create a standard xlsx file and use unique tokens for the content you want to replace. Then you can create a new xlsx file based on your "template".

We are generating large XLSX documents (only data) and we have template XLSX (styles, image, etc...).
I know XLSX is just zip, you can extract them look what is inside.
It's possible somehow to copy styles & formatting from template XLSX file to generated XLSX document (copy xl/styles.xml file and zip that again is not enough). Excel complains the file is not ok, so I think there are some consistency checks?...
Thanks
We built a Python-based tool to copy XLSX styles from one sheet to another, allowing you to essentially template the visual design of a spreadsheet and apply it to new data.

I'm creating an excel file using EPPlus from a datatable and saving it to a file, all fairly standard. This works without any hassles. However, if I create a vba project, and add any vba code, the resulting .xlsx file is suddenly corrupted. When try and open it with 2013, you get the standard error.
"Excel cannot open the file 'xyz.xlsx' because the file format or file
extension is not valid. Verify that the file extension matches the
format of the file.
If I change the extension to .xls, the file opens ok, and the script runs fine. I'm on the latest beta of Epplus (4.5.0.1). Should I just change the file extension and stick to .xls, or is there something amiss?
ExcelPackage.Workbook.CreateVBAProject()
ExcelPackage.Workbook.CodeModule.Code = "'Script is here"
Dim FInfo as new FileInfo("C:\Myfiles\ThisFile.xlsx")
ExcelPackage.SaveAs(FInfo)
You can not add VBA code to XLSX file format.
Take a look at here
.xlsx:
The default XML-based file format for Excel 2007-2013. Cannot store
Microsoft Visual Basic for Applications (VBA) macro code or Microsoft
Office Excel 4.0 macro sheets (.xlm).
Also take a look at here
to see differences between different formats:
XLSM If you include VBA macros in your XLSX file, you will be asked to
change the file extension to XLSM. Only that way you can save your
macro within the Excel file (there are other file types possible, e.g.
XLSB – but you can’t use XLSX for VBA macros)
Save your file as XLSM and it should work.
I have a google account that uses the save emails and attachments add-on.
https://chrome.google.com/webstore/detail/save-emails-and-attachmen/nflmnfjphdbeagnilbihcodcophecebc?hl=en
The email account only receives excel sheets as attachments, and those are saved to a specific folder automatically.
Is it possible to have those sheets converted automatically to google sheets upon save (or after save). Currently, I have to open the file with google sheets to convert it.
I have tried setting the folder to Convert uploaded files to Google Docs editor format, but that doesn't work for this.
Any suggestions would be greatly appreciated.

if you're wishing to do this with the Drive API, then you can do so using the examples given in Upload Files, see the section headed Importing to Google Docs types. Essentially, by setting the source file MIME type to application/vnd.openxmlformats-officedocument.spreadsheetml.sheet and that of the new file to application/vnd.google-apps.spreadsheet, this indicates that the conversion is required on upload.
I have my application reports in Excel sheet and PDF file. Now my requirement is I want compare my Excel sheet reports to PDF file, I am facing problem with comparing these two files.
My reports are in table format so I am unable identify the rows and columns in PDF. Please give some suggestions about this problem.
There is no a direct way to compare data in PDF and Excel files. You need to separately read data from both a PDF report and from an Excel sheet and compare this data in your test. Find some information on how to read content of a PDF file in Can I use TestComplete to compare PDF files? FAQ article and search the TestComplete forum - it contains a lot of discussions on how to work with PDF. Information on working with Excel files can be found in the Working With Microsoft Excel Files help topic.
Is anyone familiar with a library or tool that can determine which format an excel file is in? Or, failing that, documentation on the different formats that would allow me to write my own?
The Excel file format is called the Binary Interchange File Format (BIFF) there are different versions of Excel that use the same version of BIFF.
Open Office document on the Excel File Format.
Take a look at the Open Office API, this should help you.
Excel 97-2003 workbooks are known as Biff8. They are actually OLE Compound documents which are essentially a file system within a file. They store the main workbook in a stream named "Workbook" and they have other streams for VBA modules, OLE objects, document properties, etc...
Win32 includes APIs for reading OLE Compound Documents. They are far from trivial. Once you get the "Workbook" stream, the first Biff record identifies the file as being an Excel file.
You can find excellent documentation from Microsoft on the Biff8 file format on the Microsoft Office Binary File Formats page.
The new Excel 2007 Open XML (xlsx) format is actually a zip file with workbook parts and is documented at OpenXmlDeveloper.org.
I am not aware of a tool which will simply tell you the format of a workbook. You could take the easy, but not very reliable approach of just looking at the extension which will be right 99%+ of the time - if accuracy is not an issue.
There are many tools to read xls and xlsx workbooks, including SpreadsheetGear for .NET which reads both.
