Specify spreadsheet rendering options Leave feedback

GroupDocs.Viewer ships with the SpreadsheetOptions class that allows you to specify different spreadsheet rendering options (for example, you can display row and column headings in the output file, render grid lines, or adjust cell text overflow). To access these options, use the SpreadsheetOptions property for one of the following classes (depending on the output file format):
Rows and columns in a worksheet have unique names displayed on the worksheet’s left and top side. Rows are numbered (1, 2, 3, …, 1048576), and columns are lettered (A, B, C, …, XFD).
Enable the SpreadsheetOptions.RenderHeadings property to display row and column headings in the output file when you render your spreadsheet in HTML, PDF, PNG, or JPEG format.
The following example demonstrates how to convert an Excel workbook to PDF and display row and column headings in the output PDF file:
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PDF.
viewOptions = gvo.PdfViewOptions("output.pdf")
# Render row and column headings.
viewOptions.spreadsheet_options.render_headings = True
viewer.view(viewOptions)
The following image demonstrates the result:
Use the SpreadsheetOptions.RenderGridLines property to display gridlines (lines that separate worksheet rows and columns) in the output file.
The following code example demonstrates how to convert an Excel workbook to PDF and display gridlines in the output PDF file:
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PDF.
viewOptions = gvo.PdfViewOptions("output.pdf")
# Render grid lines.
viewOptions.spreadsheet_options.render_grid_lines = True
viewer.view(viewOptions)
The following image demonstrates the result:
The SpreadsheetOptions.TextOverflowMode option allows you to prevent text overflow in worksheet cells (see the image below) when you convert your spreadsheet file to HTML, PDF, or image format.
You can set the TextOverflowMode property to one of the following values:
TextOverflowMode.OverlayIfNextIsEmpty (default) — Allows text to overflow into adjacent cells if these cells have no data. If adjacent cells are not empty, the overflowing text is truncated.
TextOverflowMode.Overlay — Text always overflows into adjacent cells even if these cells contain data.
TextOverflowMode.AutoFitColumn — Increases the column width to fit cell text.
TextOverflowMode.HideText — Hides text that overflows the cell boundaries.
The following example demonstrates how to set this option in code:
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PDF.
viewOptions = gvo.PdfViewOptions("output.pdf")
# Specify the AutoFitColumn mode.
viewOptions.spreadsheet_options.text_overflow_mode = gvo.TextOverflowMode.AutoFitColumn
viewer.view(viewOptions)
Use the ViewOptions.SpreadsheetOptions.RenderHiddenRows and ViewOptions.SpreadsheetOptions.RenderHiddenColumns properties to display hidden rows and columns in the output file when you render your spreadsheet in HTML, PDF, PNG, or JPEG format.
The example below demonstrates how to set this option in code. The rows 20 and 21 and the column E are hidden in the source Excel workbook.
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PDF.
viewOptions = gvo.PdfViewOptions("output.pdf")
# Enable rendering hidden rows and columns.
viewOptions.spreadsheet_options.render_hidden_columns = True
viewOptions.spreadsheet_options.render_hidden_rows = True
viewer.view(viewOptions)
The image below demonstrates the result. Hidden rows and columns appear in the generated PDF file.
If your spreadsheet file contains hidden worksheets, enable the ViewOptions.RenderHiddenPages property to display data from hidden worksheets in the output HTML, PDF, or image files.
The following example demonstrates how to set this option in code:
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PDF.
viewOptions = gvo.PdfViewOptions("output.pdf")
# Enable rendering hidden pages.
viewOptions.render_hidden_pages = True
viewer.view(viewOptions)
GroupDocs.Viewer supports the SpreadsheetOptions.SkipEmptyRows and SpreadsheetOptions.SkipEmptyColumns properties that allow you to skip blank rows and columns when you convert your spreadsheet file to HTML, PDF, or image format.
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PDF.
viewOptions = gvo.PdfViewOptions("output.pdf")
# Enable skipping blank rows and columns.
viewOptions.spreadsheet_options.skip_empty_columns = True
viewOptions.spreadsheet_options.skip_empty_rows = True
viewer.view(viewOptions)
The following image demonstrates the result:
Use the ViewOptions.RenderComments option to display cell comments in the output file when you render your spreadsheet in HTML, PDF, PNG, or JPEG format.
with gv.Viewer("invoice.xlsx") as viewer:
# Convert the spreadsheet to PNG.
# {0} is replaced with the current page number in the file names.
viewOptions = gvo.PngViewOptions("output_{0}.png")
# Enable rendering comments.
viewOptions.render_comments = True
viewer.view(viewOptions)
The following image demonstrates the result:
Use the SpreadsheetOptions.RenderGridLines properties to set margins for worksheets in the output pdf. If margins are set to value less than 0 or not set then default value will be used.
The following code example demonstrates how to convert an Excel workbook to PDF and set optional margins for worksheets in the output PDF file:
with gv.Viewer("invoice.xlsx") as viewer:
viewOptions = gvo.PdfViewOptions("output.pdf")
# Set margins for worksheets in the output pdf pages
viewOptions.spreadsheet_options.left_margin = 0;
viewOptions.spreadsheet_options.right_margin = 0.5;
viewOptions.spreadsheet_options.top_margin = 1;
viewOptions.spreadsheet_options.bottom_margin = -10; # set to default value
viewer.view(viewOptions)
The following image demonstrates the result:
