Hi,
Thanks for the sample file and screenshot.
I am afraid, this is not an issue with the product as Aspose.Cells saves Excel to HTML rendering as you manually do it via the following steps (in MS Excel):
- Open the Excel file into MS Excel.
- Save it as “Web Page” (either whole workbook or active worksheet).
I have tested using the above steps and check the output HTML file’s source, it does produce the same result as per the output HTML file by Aspose.Cells APIs. Aspose.Cells does not (by default) support to export an area in the sheet to HTML, so you will see those blank cells are not documented.
Thank you.
Based on the steps you provided I retested the same but getting the same results. You can refer to the image attached earlier. Make sure to compare the html source in text editor and not in the browser.
Thanks,
Neha
