Can't save xlsx file to html

Hi, i’m trying to save this xlsx file to html format and facing an issue.
The programm is trying to do it during a long time and eating a lot of memory (file is small), but can’t finish.
I think that it’s related with a table formating of whole sheet. But MS Excel is converting this file to html very fast (reducing empty rows at the end of sheet).
Source file:
TEST.zip (10.0 KB)

C# code sample:
Workbook wb = new Workbook(@“C:\TEST.xlsx”, new LoadOptions() { MemorySetting = MemorySetting.MemoryPreference });
HtmlSaveOptions so = new HtmlSaveOptions(SaveFormat.Html);
wb.Save(@“C:\TEST.html”, so);
How can I convert such file to html?
Thank you.

How soon we can get version with this fix from NuGet?


We only publish official releases on Nuget\maven repos. The hotfix, i.e., Aspose.Cells for .NET v18.7.4 is fully tested and includes all the features (full fledged) and previous fixes and enhancements, so you may use it on production server. It is safe to use the hotfix on the server. However, if you still want the version to be uploaded onto Nuget, then you have to wait for our next official release of the product. We will publish our next official release, i.e., Aspose.Cells for .NET v18.8 (which will also include your fix) in the third week of August, 2018.
