Hello!
I am trying to save docx to html. but im getting an exception while executing the below code

Document docMaster = new Document(System.IO.Path.Combine(storagePath, "abc.docx"));
MemoryStream stream = new MemoryStream();
HtmlSaveOptions options2 = new HtmlSaveOptions(SaveFormat.Html)
{
    ExportTextInputFormFieldAsText = true,
    ExportImagesAsBase64 = true,
    CssStyleSheetType = CssStyleSheetType.Embedded,
    ExportFontsAsBase64 = true,
    DocumentSplitCriteria = DocumentSplitCriteria.PageBreak,
    ExportPageMargins = true,
    ExportShapesAsSvg = true,
    HtmlVersion = HtmlVersion.Html5,
    UseHighQualityRendering = true,
    ExportTocPageNumbers = true,
    ExportRelativeFontSize = true,
    ExportDocumentProperties = true,
};
options2.ExportHeadersFootersMode = ExportHeadersFootersMode.PerSection;

docMaster.Save(stream, options2);

exception message: Document part file cannot be written. When saving the document either output file name should be specified or custom streams should be provided via DocumentPartSavingCallback. Please see documentation for details.

@vineeth.pv The problem occurs because you are using DocumentSplitCriteria = DocumentSplitCriteria.PageBreak and your input document contains page breaks. When DocumentSplitCriteria is used several HTML files might be generated, but in case of saving to a Stream Aspose.Words does not know where to save these document parts. So simple remove DocumentSplitCriteria = DocumentSplitCriteria.PageBreak from your HtmlSaveOptions and in this case Aspose.Words will save the whole document into once HTML file.

@alexey.noskov I tried the same but in the converted html file missing few contents of the word document

@vineeth.pv Could you please attach your input document here for testing and highlight what content is missed after conversion? We will check the issue and provide you more information.

@vineeth.pv Thank you for additional information. But could you please also specify what content is messed? As I can see all content is exported to HTML.
By the way, if you need an exact visual representation of your source document in HTML, you can consider using SaveFormat.HtmlFixed. In this case document is rendered to pages and looks the same as it looks in MS Word. But note this format is not designed for editing.

HtmlFixedSaveOptions options = new HtmlFixedSaveOptions()
{
    ExportEmbeddedCss = true,
    ExportEmbeddedFonts = true,
    ExportEmbeddedImages = true,
    ExportEmbeddedSvg = true
};
