Hello,

As per my client requirement I have to convert word document to html string for that I m using Aspose.Words library . It is a trial version.
I m using following code for converting word doc to html string . It is converting 95 % doc content correctly . I have attached the sample doc . Please check at your end also.
After conversion I m loosing some formatting of word document.
Whether it is the limitation of Aspose.Words library or It is happening because using trial version-ed library.

string htmlString=string.Empty;
Aspose.Words.Saving.HtmlSaveOptions htmlSaveOptions = new Aspose.Words.Saving.HtmlSaveOptions();
htmlSaveOptions.ExportImagesAsBase64 = true;
htmlSaveOptions.ExportHeadersFooters = true;
htmlSaveOptions.ExportHeadersFootersMode = Aspose.Words.Saving.ExportHeadersFootersMode.PerSection;
htmlSaveOptions.SaveFormat = Aspose.Words.SaveFormat.Html;
htmlSaveOptions.PrettyFormat = true;
Aspose.Words.Document doc = new Aspose.Words.Document(sourceFilePath);
string destinationFileName = sourceFilePath.Split(’.’)[0] + ".html";
// Save the document in html format.
doc.Save(destinationFileName, htmlSaveOptions);
htmlString = System.IO.File.ReadAllText(destinationFileName);

Confirmation is needed on this so that I can inform same to my manager whether to purchase or not?

I will be waiting for your reply.

Thank you.

Hi there,

Thanks for sharing the detail. Please note that Aspose.Words mimics the same behavior as MS Word does. If you convert your document to Html using MS Word, you will get the same output.

To workaround this issue, please remove the hidden paragraphs and list items without text from the document. Please check following code example for your kind reference. Regarding shape position issue, we suggest you please change its position from left to right to fix this issue. Hope this helps you.

Document doc = new Document(MyDir + "in.doc");
foreach (Paragraph par in doc.GetChildNodes(NodeType.Paragraph, true))
{
    par.ParagraphFormat.LeftIndent = par.ParagraphFormat.LeftIndent + 40;
    if ((par.ParagraphBreakFont.Hidden && par.ToString(SaveFormat.Text).Trim() == "")
    || (par.IsListItem && par.ToString(SaveFormat.Text).Trim() == ""))
    {
        par.Remove();
        continue;
    }
    foreach (Run run in par.GetChildNodes(NodeType.Run, true).ToArray())
    {
        if (run.Font.Hidden)
            run.Remove();
    }
}
doc.Save(MyDir + "Out.html");

Thanks Tahir.
I tried posted code , up to some extent it is working fine but not converting word to html string with 100% accuracy. If this problem remains there after purchasing also it will problem to me.

I was converting word to html string conversion using OpenXML , with this I faced the same issue. Because of this reason we have planned to purchase third party tool for same purpose But Third Party tools also having limitation like ASPOSE.WORDS :).

This I have to discuss with my manager. If they accept it then We will purchase it.

Do you have any other solution for this issue.

If you have any other solution which converts word to html string with 100% accuracy please let me know.

Hi there,

Raju Arge:

For the sake of correction, we have logged this problem in our issue tracking system as WORDSNET-12734. You will be notified via this forum thread once this issue is resolved.

Hi there,

Thanks for your patience. It is to inform you that our product team has completed the work on this issue (WORDSNET-12734) and has come to a conclusion that this issue and the undesired behavior you’re observing is actually not a bug in Aspose.Words. So, we have closed this issue as ‘Not a Bug’. We are quoting developer’s comments here for your reference.

In customer’s document paragraph is list item and has highlight color in it’s rPr properties. When exporting to HTML with HtmlSaveOptions.ExportListLabels = ExportListLabels.ByHtmlTags we apply this highlight color as li’s background-color, so background color occupies all space to the right of the page. When exporting to HTML with HtmlSaveOptions.ExportListLabels = ExportListLabels.AsInlineText we apply highlight color as background-color only to span which represents list bullet.

Please use ExportListLabels.AsInlineText as shown in following code example to get the desired output.

Document doc = new Document(MyDir + “in.doc”);
Aspose.Words.Saving.HtmlSaveOptions options = new Aspose.Words.Saving.HtmlSaveOptions();
options.ExportListLabels = ExportListLabels.AsInlineText;
doc.Save(MyDir + “Out.html”, options);

Please let us know if you have any more queries.

Original content :

Aspose.Words .net library is not converting table content exactly into html string.

If you have solution for this problem please let me know.

Hi there,

Thanks for your inquiry. HtmlSaveOptions.ExportTocPageNumbers property specifies whether to write page numbers to table of contents when saving HTML, MHTML and EPUB. Default value is false. Please set the value of this property to true to get the required output.

Aspose.Words.Saving.HtmlSaveOptions options = new Aspose.Words.Saving.HtmlSaveOptions();
options.ExportListLabels = ExportListLabels.AsInlineText;
options.ExportTocPageNumbers = true;
doc.Save(MyDir + " Out.html", options);

Hi there,

Thanks for your inquiry. HtmlSaveOptions.ExportListLabels property controls how list labels are output to HTML, MHTML or EPUB.

AsInlineText : Outputs all list labels as inline text.
ByHtmlTags : Outputs all list labels as HTML native elements.

If you want to get the list labels as HTML native elements, please use ExportListLabels.ByHtmlTags. However, by using this option, the highlighted color issue appears. Please check this post for detail.

Please note that Aspose.Words mimics the same behavior as MS Word does. Upon processing HTML, some features of HTML might be lost. You can find a list of limitations upon HTML exporting/importing here:
Load in the HTML (.HTML, .XHTML, .MHTML) Format
Save in the HTML (.HTML, .XHTML, .MHTML) Format
