Excel to HTML conversion. Quality

I am using Aspose.Cells to convert Excel files to HTML.
I have a couple of Excel files, the HTML for them looks broken.

You may try to set PresentationPreference option mode on to get better display with elegant quality regarding formattings. I tried the following sample code and it works fine:
Sample code:

     Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook("e:\\test2\\example_1.xls");
                HtmlSaveOptions options = new HtmlSaveOptions();
                options.PresentationPreference = true;
                options.ExportHiddenWorksheet = false;
                options.ExportPrintAreaOnly = true;
    workbook.Save("e:\\test2\\out1.html", options);

This code helps for the first file but does not help for the second one.


Yes, we noticed the issue. I am able to observe the issue even using PresentationPreference option. I found some multiline text in some cells (for “example_2.xlsx” file) is not rendered properly in Excel to HTML conversion. I have logged a ticket with an id “CELLSNET-49452” for your issue. We will look into it soon.

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