Hiding or unhiding rows and columns in Excel gives you precise control over the visibility of specific data within a worksheet. By hiding rows or columns, you can temporarily remove irrelevant information from view, reducing visual clutter and creating a cleaner workspace. This makes it easier to work with the data that truly matters and enhances your productivity. On the other hand, unhiding rows or columns allows you to restore visibility and regain access to previously hidden information whenever you need it. This is advantageous when you have hidden data that requires further review, modification, or analysis.

Text wrapping and unwrapping are powerful formatting options in Microsoft Excel that offer flexibility in displaying text within cells. When text wrapping is enabled, long text is automatically wrapped into multiple lines within a cell, which ensures that the entire content is visible without truncation. This feature is particularly useful for presenting lengthy descriptions, notes, or paragraphs within a confined cell space. On the other hand, text unwrapping allows you to remove line breaks and display the text in a single line within the cell. This can be beneficial in scenarios where you need to fit the text into a specific layout or when exporting data to other applications or file formats that may not handle wrapped text correctly. In this article, we will demonstrate how to wrap or unwrap text in Excel cells in Python using Spire.XLS for Python.

Install Spire.XLS for Python

This scenario requires Spire.XLS for Python and plum-dispatch v1.7.4. They can be easily installed in your Windows through the following pip command.

pip install Spire.XLS

Wrap or Unwrap Text in Excel Cells in Python

Spire.XLS for Python provides the CellStyle.WrapText property to control whether the text should be wrapped or unwrapped within a cell. If you want to wrap text in a cell, you can set the property as True. Conversely, if you want to unwrap text in a cell, you can set the property as False.

The following steps explain how to wrap or unwrap text in an Excel cell using Spire.XLS for Python:

• Create a Workbook object.
• Load a sample Excel file using Workbook.LoadFromFile() method.
• Get a specified worksheet using Workbook.Worksheets[] property.
• Get a specified cell using Worksheet.Range[] property.
• Get the style of the specified cell using CellRange.Style property.
• Wrap the text in the cell by setting the CellStyle.WrapText property to True. Or unwrapping the text in the cell by setting the CellStyle.WrapText property to False.
• Save the resulting file using Workbook.SaveToFile() method.

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()
# Load a sample Excel file
workbook.LoadFromFile("Sample.xlsx")

# Get the first worksheet of the file
sheet = workbook.Worksheets[0]

# Wrap the text in cell B3
sheet.Range["B3"].Style.WrapText = True

# Unwrap the text in cell B7
sheet.Range["B7"].Style.WrapText = False

#Save the resulting file
workbook.SaveToFile("WrapOrUnwrapTextInCells.xlsx", ExcelVersion.Version2013)
workbook.Dispose()

Merging cells means combining multiple adjacent cells into a larger one. The merged cell will inherit all the properties and contents of the original cells. This feature is particularly useful when you need to create a larger cell to accommodate more content or create a header row. Unmerging cells, on the other hand, involves reverting the merged cells back to the original multiple cells. The unmerged cells will revert back to their original independent state, and you can input different content into each individual cell. Merging and unmerging cells are common operations in spreadsheet software, allowing you to adjust the layout and structure of a table as needed, making the data clearer and easier to understand. In this article, you will learn how to merge or unmerge cells in Excel in Python by using Spire.XLS for Python.
