Hi,


Thanks for your query.

Well, Aspose.Cells follows Ms Excel standards and specification while rendering XLS/XLSX files. Aspose.Cells does not support to create XLS file from XSLT schema. I think if your created XLS file (using Xslt schema) is opened fine into MS Excel manually and follows the standard specifications, Aspose.Cells should not have any issue while converting XLS to XLSX or other file formats.

If you still think there is some issue with the XLS (using your Xlst schema) to XLSX conversion via Aspose.Cells APIs where MS Excel does perform the job, share the template XLS file here, we will check it soon.

Thank you.

Hi,


Thanks for providing us template file.

After an intial test, I observed an exception: “Input string was not in a correct format.” while loading your so called XLS file which is actually a common HTML file (as you created from XSLT) and does not conform to MS Excel standards and specifications regarding HTML file format. For confirmation, you may simply try to open into MS Excel manually and MS Excel will prompt an error. Anyways, I tried the following sample code with your template file.
e.g
Sample code:

Workbook workbook = new Workbook(@“e:\test2\Job_243036.xls”, new LoadOptions(LoadFormat.Html));
workbook.Save(@“e:\test2\out1Job_2430361.xlsx”, SaveFormat.Xlsx);

I have logged a ticket with an id “CELLSNET-44179” for your issue. We will check and investigate if we could support loading such a file (which does not seem to conform to MS Excel standards and specifications) into Aspose.Cells’ object model.

Once we have an update on it, we will let you know here.

Thank you.

Hi,


If you need to create the XLS/XLSX files from the scratch using Aspose.Cells APIs, see the Aspose.Cells Wiki Conf. Docs for your reference (browse the section/sub-sections to check different documents/articles):
https://docs.aspose.com/display/cellsnet/Home

Hope, this helps a bit.

Thank you.
