Long conversion time to HTML for certain DOC file in .NET

It takes about 120 seconds to convert a single page for the attached document.
LongPageConversionTime.zip (208.4 KB)

We were using GroupDocs.Viewer 21.3 in .NET with simple conversion to HTML:

       using (var viewer = new Viewer(documentPath))
       {
           var info = viewer.GetViewInfo(ViewInfoOptions.ForHtmlView());
           var options = ViewOpts.HtmlViewOptions.ForEmbeddedResources("output_viewer{0}.html");
           viewer.View(options);
       }

I also noticed that the GetViewInfo (“info”) shows only 143 pages, but when opening the file in Word there are 325 pages.

I tried to reproduce wrong pages count case, but Microsoft Word 2016 shows 143 pages too:

Which version of Microsoft Word are you using?

Thank you for checking the issue.
I’m surprised that it only has 143 pages for you, as I am also using Word 2016:

I think most of the “missing” pages are auto-generated, like table of contents or the index at the end

Does it generate the Index on your side?

@Clemens_Pestuka seems Microsoft Word counts pages wrongly.

Is background repagination is turned on?

Check it with this manual

Also to check a final number of pages, you can print document from Word to PDF and get an actual number of pages.

You are right, it’s really Word that counts the pages incorrectly.
Thank you :slight_smile:
