openpyxl.cell.cell module¶

The Cell class is required to know its value and type, display options, and any other features of an Excel cell. Utilities for referencing cells using Excel’s ‘A1’ column/row nomenclature are also provided.

class openpyxl.cell.cell. Cell ( worksheet, row=None, column=None, value=None, style_array=None ) [source] ¶

Describes cell associated properties.

Properties of interest include style, type, value, and address.

base_date ¶ check_error ( value ) [source] ¶

Tries to convert Error” else N/A

Check string coding, length, and line break character

The numerical index of the column

Column number of this cell (1-based)

Returns the comment associated with this cell

Type:	openpyxl.comments.Comment

coordinate ¶

This cell’s coordinate (ex. ‘A5’)

data_type ¶ encoding ¶ hyperlink ¶

Return the hyperlink target or an empty string

Always returns the value for excel.

True if the value is formatted as a date

Type:	bool

offset ( row=0, column=0 ) [source] ¶

Returns a cell location relative to this cell.

Row number of this cell (1-based)

Get or set the value held in the cell.

Type:	depends on the value (string, float, int or datetime.datetime )

class openpyxl.cell.cell. MergedCell ( worksheet, row=None, column=None ) [source] ¶

Describes the properties of a cell in a merged cell and helps to display the borders of the merged cell.

The value of a MergedCell is always None.

column ¶ comment = None¶ coordinate ¶

This cell’s coordinate (ex. ‘A5’)

data_type = ‘n’¶ hyperlink = None¶ row ¶ value = None¶ openpyxl.cell.cell. WriteOnlyCell ( ws=None, value=None ) [source] ¶ openpyxl.cell.cell. get_time_format ( t ) [source] ¶ openpyxl.cell.cell. get_type ( t, value ) [source] ¶

openpyxl.worksheet.dimensions module¶

class openpyxl.worksheet.dimensions. ColumnDimension ( worksheet, index=’A’, width=13, bestFit=False, hidden=False, outlineLevel=0, outline_level=None, collapsed=False, style=None, min=None, max=None, customWidth=False, visible=None, auto_size=None ) [source] ¶

Information about the display properties of a column.

Aliases can be used when either the desired attribute name is not allowed or confusing in Python (eg. “type”) or a more descriptive name is desired (eg. “underline” for “u”)

Always true if there is a width for the column

Set boundaries for column definition

class openpyxl.worksheet.dimensions. Dimension ( index, hidden, outlineLevel, collapsed, worksheet, visible=True, style=None ) [source] ¶

Information about the display properties of a row or column.

Aliases can be used when either the desired attribute name is not allowed or confusing in Python (eg. “type”) or a more descriptive name is desired (eg. “underline” for “u”)

class openpyxl.worksheet.dimensions. DimensionHolder ( worksheet, reference=’index’, default_factory=None ) [source] ¶

Allow columns to be grouped

allow grouping a range of consecutive rows or columns together

start – first row or column to be grouped (mandatory)
end – last row or column to be grouped (optional, default to start)
outline_level – outline level
hidden – should the group be hidden on workbook open or not

Information about the display properties of a row.

Always true if there is a style for the row

Always true if there is a height for the row

Aliases can be used when either the desired attribute name is not allowed or confusing in Python (eg. “type”) or a more descriptive name is desired (eg. “underline” for “u”)

class openpyxl.worksheet.dimensions. SheetDimension ( ref=None ) [source] ¶

tagname = ‘dimension’¶ class openpyxl.worksheet.dimensions. SheetFormatProperties ( baseColWidth=8, defaultColWidth=None, defaultRowHeight=15, customHeight=None, zeroHeight=None, thickTop=None, thickBottom=None, outlineLevelRow=None, outlineLevelCol=None ) [source] ¶

tagname = ‘sheetFormatPr’¶ thickBottom ¶

How to change or modify column width size in Openpyxl

Microsoft Excel is one of the most widely used tools today. Most software projects intend to use it for organizing data. Thus it becomes necessary to have easy ways to access Excel sheets without opening the application every time. Python provides you ways to operate on excel without directly opening the software, through the openpyxl library.
By now, you may be familiar with the various operations you can perform using openpyxl. ( iter_rows, fill cells with colors using openpyxl)
This tutorial will teach you how to modify column width size in openpyxl.

Installing openpyxl

First of all, you must make sure to install the openpyxl library. You can do the same by running the below command on your terminal.

To change or modify column width size

In order to change the column width size, you can make use of the column_dimesnsions method of the worksheet class.
Syntax: worksheet.column_dimensions[column name].width=size

Let us look into the same with example below.

Consider an existing excel file codespeedy.xlsx as shown below;

So, now let us change the column size of column A;

import openpyxl worksheet = openpyxl.load_workbook("codespeedy.xlsx") sheet = worksheet.active sheet.column_dimensions['A'].width = 20 worksheet.save("codespeedy1.xlsx")

As you can see, we have modified the column size of A to 20 and saved the file after modification as codespeedy1.xlsx.

Similarly, you can also modify the column width of many rows as shown;

import openpyxl worksheet = openpyxl.load_workbook("codespeedy.xlsx") sheet = worksheet.active sheet.column_dimensions['A'].width = 20 sheet.column_dimensions['C'].width = 20 sheet.column_dimensions['E'].width = 30 worksheet.save("codespeedy1.xlsx")

Well, isn’t it amazing how you can manage such significant changes with such simple, small lines of code? Well, that in itself is the beauty of Python.

Worksheet Tables¶

Worksheet tables are references to groups of cells. This makes certain operations such as styling the cells in a table easier.

Creating a table¶

from openpyxl import Workbook from openpyxl.worksheet.table import Table, TableStyleInfo wb = Workbook() ws = wb.active data = [ ['Apples', 10000, 5000, 8000, 6000], ['Pears', 2000, 3000, 4000, 5000], ['Bananas', 6000, 6000, 6500, 6000], ['Oranges', 500, 300, 200, 700], ] # add column headings. NB. these must be strings ws.append(["Fruit", "2011", "2012", "2013", "2014"]) for row in data: ws.append(row) tab = Table(displayName="Table1", ref="A1:E5") # Add a default style with striped rows and banded columns style = TableStyleInfo(name="TableStyleMedium9", showFirstColumn=False, showLastColumn=False, showRowStripes=True, showColumnStripes=True) tab.tableStyleInfo = style ''' Table must be added using ws.add_table() method to avoid duplicate names. Using this method ensures table name is unque through out defined names and all other table name. ''' ws.add_table(tab) wb.save("table.xlsx")

Table names must be unique within a workbook. By default tables are created with a header from the first row and filters for all the columns and table headers and column headings must always contain strings.

In write-only mode you must add column headings to tables manually and the values must always be the same as the values of the corresponding cells (ee below for an example of how to do this), otherwise Excel may consider the file invalid and remove the table.

Styles are managed using the the TableStyleInfo object. This allows you to stripe rows or columns and apply the different colour schemes.

Working with Tables¶

ws.tables is a dictionary-like object of all the tables in a particular worksheet:
