Excel file > html loads very slow

The attached file has 3 tabs, when converting to HTML there are 2 very large tabs which take a very long time to open in a browser.
When converted a folder is created with 6 files within it.

Can you provide suggestions?

Hi,

Thanks for your posting and using Aspose.Cells.

It seems, the total size of your output html directory is around 30MB. However, we could not test your issue because the attachment (i.e vostok2011ecm.xlsx) is lost. Will you please re-attach your excel file?

Please also download and use the latest version:
Aspose.Cells for .NET (Latest Version) and see if it makes any difference and resolves your issue. Let us know your feedback.

I have uploaded the file here again.
thanks.

Hi,


Thanks for providing us template Excel file.

Well, I have checked your template Excel file which contains two big worksheets. I can see your third worksheet has over 150K records in it. So, when you do convert the workbook (with long list of data in second and third worksheets) to HTML file format via Aspose.Cells for .NET APIs, second and third worksheets (sheet002.htm and sheet003.htm) takes some time to be loaded into the browser (e.g IE). I also checked that the third sheet has over 26MB size which is obviously is a big file and the browser takes some time to load it completely. I then tried to accomplish the same task in MS Excel manually, I simply save your Excel file as a “Web Page”. Now when I open the output HTML file into the browser, the second and third worksheets also take similar (of more) time to be loaded when I clicked on the second or third (especially) tab in the browser. So, it is not an issue in Aspose.Cells APIs by any means as it does mimic the same as per MS Excel. For your information, Aspose.Cells does render HTML files from spreadsheets as you manually do it via MS Excel, Aspose.Cells follows MS Excel standards and specifications while rendering to HTML file format.

Thank you.
