Excel to HTML - Use PresentationPreference Option for Better Layout with JavaScript via C++
Contents

]
Aspose.Cells provides a useful HtmlSaveOptions.presentationPreference property for developers who need to render better layout when saving a Microsoft Excel file to HTML or MHT format. The default value of the property is false. We recommend setting this property to true to get a more attractive presentation of Excel reports.
Please see the sample code below that demonstrates how to render an HTML file from an Excel report with presentation preference on.

<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Run Example</button>
