Disable Downlevel Revealed Comments while saving to HTML

When an Excel file is converted to HTML, Aspose.Cells adds Downlevel-revealed conditional comments to the output HTML file. These conditional comments are mostly relevant to old versions of Internet Explorer and are irrelevant in modern browsers. For additional information on Downlevel-revealed conditional comments, please visit the following link:

Pythonjava: Exclude Unused Styles during Excel to HTML conversion

Mon, 01 Jan 0001 00:00:00 +0000

Exclude Unused Styles during Excel to HTML conversion

Microsoft Excel files may contain many unused styles. When these files are exported to HTML format, the unused styles are also exported. This results in an increased size of the output HTML. Aspose.Cells for Python via Java supports excluding these styles during the conversion of an Excel file to HTML. For this, the API provides the HtmlSaveOptions.ExcludeUnusedStyles property. Setting the value of HtmlSaveOptions.ExcludeUnusedStyles property to True will exclude all unused styles from the output HTML.

The following screenshot shows unused styles in the HTML file, which will be removed by setting the value of HtmlSaveOptions.ExcludeUnusedStyles property to True.

The following sample code demonstrates removing unused styles during Excel to HTML conversion.

Pythonjava: Get HTML5 string from Cell

Mon, 01 Jan 0001 00:00:00 +0000

Get HTML5 string from Cell

Using Aspose.Cells for Python via Java, you can get the HTML string from the cell. This can be achieved by using the getHtmlString(boolean html5) method provided by the API. If you pass false as a parameter, it will return normal HTML, but if you pass true, it will return an HTML5 string.

The following sample code creates a workbook object and adds some text in cell A1 of the first worksheet. It then gets the Normal HTML and HTML5 string from cell A1 using the getHtmlString(boolean html5) method and prints them.

Sample Code

The following is the output generated by the above-provided code snippet.

Output

 Normal:

<Font Style="FONT-FAMILY: Arial;FONT-SIZE: 10pt;COLOR: #000000;">This is some text.</Font>

HTML5:

<div Style="FONT-FAMILY: Arial;FONT-SIZE: 10pt;COLOR: #000000;">This is some text.</div>

When Excel is converted to HTML, comments are not exported. Aspose.Cells for Python via Java provides a feature to export comments when converting Excel to HTML. To achieve this, the API provides the HtmlSaveOptions.IsExportComments property. Setting the value of HtmlSaveOptions.IsExportComments property to True will export comments in the output HTML.

The following screenshot shows the output HTML file generated by the sample code snippet.

The following sample code demonstrates exporting comments during Excel to HTML conversion.

Pythonjava: Export print area range to HTML

Mon, 01 Jan 0001 00:00:00 +0000

Export print area range to HTML

Aspose.Cells for Python via Java supports exporting only the print area, i.e., a selected range of cells, instead of the entire sheet to HTML. For this, the API provides the HtmlSaveOptions.ExportPrintAreaOnly property. Setting this property to True will only export the print area.

The following sample code demonstrates the use of the HtmlSaveOptions.ExportPrintAreaOnly property to export only the print area to HTML.

Pythonjava: Excel with unsupported border style to HTML

Mon, 01 Jan 0001 00:00:00 +0000

Excel with unsupported border style to HTML

Microsoft Excel supports some types of dashed borders that are not supported by web browsers. When such files are converted to HTML using Aspose.Cells, those borders are removed. However, Aspose.Cells for Python via Java supports displaying similar borders with the HtmlSaveOptions.ExportSimilarBorderStyle property. You may set the value of the HtmlSaveOptions.ExportSimilarBorderStyle property to True to export unsupported borders.

The following sample code loads the sample Excel file that contains some unsupported borders as shown in the following screenshot. The screenshot further illustrates the effect of the HtmlSaveOptions.ExportSimilarBorderStyle property in the output HTML (outputExportSimilarBorderStyle.zip).
