Setting styles in Openpyxl

Question

I need advice on setting styles in Openpyxl.

I see that the NumberFormat of a cell can be set, but I also require setting of font colors and attributes (bold etc). T

Answer 1

As of openpyxl 2.0, setting cell styles is done by creating new style objects and by assigning them to properties of a cell.

There are several style objects: Font, PatternFill, Border, and Alignment. See the doc.

To change a style property of a cell, first you either have to copy the existing style object from the cell and change the value of the property or you have to create a new style object with the desired settings. Then, assign the new style object to the cell.

Example of setting the font to bold and italic of cell A1:

from openpyxl import Workbook
from openpyxl.styles import Font
# Create workbook
wb = Workbook()
# Select active sheet
ws = wb.active()
# Select cell A1
cell = ws['A1']
# Make the text of the cell bold and italic
cell.font = cell.font.copy(bold=True, italic=True)
