Export Worksheet CSS Separately in Output HTML

Possible Usage Scenarios

Aspose.Cells for Python via .NET provides the feature to export worksheet CSS separately when you convert your Excel file to HTML. Please use HtmlSaveOptions.export_worksheet_css_separately property for this purpose and set it to true while saving Excel file to HTML format.

Export Worksheet CSS Separately in Output HTML

The following sample code creates an Excel file, adds some text in cell B5 in Red color and then saves it in HTML format using HtmlSaveOptions.export_worksheet_css_separately property. Please see the output HTML generated by the code for reference. You will find stylesheet.css inside it as an outcome of the sample code.

Sample Code

from aspose.cells import HtmlSaveOptions, Workbook
from aspose.pydrawing import Color


# Create workbook object
wb = Workbook()
# Access first worksheet
ws = wb.worksheets[0]
# Access cell B5 and put value inside it
cell = ws.cells.get("B5")
cell.put_value("This is some text.")
# Set the style of the cell - font color is Red
st = cell.get_style()
st.font.color = Color.red
cell.set_style(st)
# Specify html save options - export worksheet css separately
opts = HtmlSaveOptions()
opts.export_worksheet_css_separately = True
# Save the workbook in html
wb.save("outputExportWorksheetCSSSeparately.html", opts)

Export single sheet workbook to HTML

When a workbook with multiple sheets is converted to HTML using Aspose.Cells for Python via .NET, it creates an HTML file along with a folder containing CSS and multiple HTML files. When this HTML file is opened in the browser, the tabs are visible. The same behavior is required for a workbook with single worksheet when it is converted to HTML. Earlier no separate folder was created for single sheet workbooks and only HTML file was created. Such HTML file does not show tab when opened in browser. MS Excel creates proper folder and HTML for a single sheet also and hence same behavior is implemented using Aspose.Cells for Python via .NET APIs. The sample file can be downloaded from the following link for using in the sample code below:

sampleSingleSheet.xlsx

Sample Code

from aspose.cells import HtmlSaveOptions, Workbook

# Source directory
sourceDir = "./"
# Output directory
outputDir = "./"
#  Load the sample Excel file containing single sheet only
wb = Workbook(sourceDir + "sampleSingleSheet.xlsx")
#  Specify HTML save options
options = HtmlSaveOptions()
#  Set optional settings if required
options.encoding = "utf-8"
options.export_images_as_base64 = True
options.export_grid_lines = True
options.export_similar_border_style = True
options.export_bogus_row_data = True
options.exclude_unused_styles = True
options.export_hidden_worksheet = True
# Save the workbook in Html format with specified Html Save Options
wb.save(outputDir + "outputSampleSingleSheet.htm", options)
