As a popular open source development project, Python has an activesupporting community of contributors and users that also make their softwareavailable for other Python developers to use under open source license terms.

I want to install openpyxl on my Mac for a survey project that I am doing, however I ran into some issues in the process. I think python 2.7 is the preinstalled. Openpyexcel is a fork of openpyxl that has some additional improvements, most notably the ability to write formula values. Openpyexcel is a Python library to read/write Excel 2010 xlsx/xlsm/xltx/xltm files. It was born from lack of existing library to read/write natively from Python the Office Open XML format. # Install C: pip install openpyxl Collecting openpyxl. Successfully built openpyxl Installing collected packages: openpyxl Successfully installed openpyxl-3.0.3 WARNING: You are using pip version 19.3.1; however, version 20.0.2 is available. You should consider upgrading via the 'python -m pip install -upgrade pip' command.

This allows Python users to share and collaborate effectively, benefitingfrom the solutions others have already created to common (and sometimeseven rare!) problems, as well as potentially contributing their ownsolutions to the common pool.

This guide covers the installation part of the process. For a guide tocreating and sharing your own Python projects, refer to thedistribution guide.

Note

For corporate and other institutional users, be aware that manyorganisations have their own policies around using and contributing toopen source software. Please take such policies into account when makinguse of the distribution and installation tools provided with Python.

Key terms¶

• pip is the preferred installer program. Starting with Python 3.4, itis included by default with the Python binary installers.

• A virtual environment is a semi-isolated Python environment that allowspackages to be installed for use by a particular application, rather thanbeing installed system wide.

• venv is the standard tool for creating virtual environments, and hasbeen part of Python since Python 3.3. Starting with Python 3.4, itdefaults to installing pip into all created virtual environments.

• virtualenv is a third party alternative (and predecessor) tovenv. It allows virtual environments to be used on versions ofPython prior to 3.4, which either don’t provide venv at all, oraren’t able to automatically install pip into created environments.

• The Python Packaging Index is a publicrepository of open source licensed packages made available for use byother Python users.

• the Python Packaging Authority is the group ofdevelopers and documentation authors responsible for the maintenance andevolution of the standard packaging tools and the associated metadata andfile format standards. They maintain a variety of tools, documentation,and issue trackers on both GitHub andBitbucket.

• distutils is the original build and distribution system first added tothe Python standard library in 1998. While direct use of distutils isbeing phased out, it still laid the foundation for the current packagingand distribution infrastructure, and it not only remains part of thestandard library, but its name lives on in other ways (such as the nameof the mailing list used to coordinate Python packaging standardsdevelopment).

Changed in version 3.5: The use of venv is now recommended for creating virtual environments.

Basic usage¶

The standard packaging tools are all designed to be used from the commandline.

The following command will install the latest version of a module and itsdependencies from the Python Packaging Index:

Note

For POSIX users (including Mac OS X and Linux users), the examples inthis guide assume the use of a virtual environment.

For Windows users, the examples in this guide assume that the option toadjust the system PATH environment variable was selected when installingPython.

It’s also possible to specify an exact or minimum version directly on thecommand line. When using comparator operators such as >, < or some otherspecial character which get interpreted by shell, the package name and theversion should be enclosed within double quotes:

Normally, if a suitable module is already installed, attempting to installit again will have no effect. Upgrading existing modules must be requestedexplicitly:

More information and resources regarding pip and its capabilities can befound in the Python Packaging User Guide.

Creation of virtual environments is done through the venv module.Installing packages into an active virtual environment uses the commands shownabove.

How do I …?¶

These are quick answers or links for some common tasks.

… install pip in versions of Python prior to Python 3.4?¶

Python only started bundling pip with Python 3.4. For earlier versions,pip needs to be “bootstrapped” as described in the Python PackagingUser Guide.

… install packages just for the current user?¶

Passing the --user option to python-mpipinstall will install apackage just for the current user, rather than for all users of the system.

… install scientific Python packages?¶

A number of scientific Python packages have complex binary dependencies, andaren’t currently easy to install using pip directly. At this point intime, it will often be easier for users to install these packages byother meansrather than attempting to install them with pip.

… work with multiple versions of Python installed in parallel?¶

On Linux, Mac OS X, and other POSIX systems, use the versioned Python commandsin combination with the -m switch to run the appropriate copy ofpip:

Appropriately versioned pip commands may also be available.

On Windows, use the py Python launcher in combination with the -mswitch:

Common installation issues¶

Installing into the system Python on Linux¶

On Linux systems, a Python installation will typically be included as partof the distribution. Installing into this Python installation requiresroot access to the system, and may interfere with the operation of thesystem package manager and other components of the system if a componentis unexpectedly upgraded using pip.

On such systems, it is often better to use a virtual environment or aper-user installation when installing packages with pip.

Pip not installed¶

It is possible that pip does not get installed by default. One potential fix is:

There are also additional resources for installing pip.

Installing binary extensions¶

Python has typically relied heavily on source based distribution, with endusers being expected to compile extension modules from source as part ofthe installation process.

With the introduction of support for the binary wheel format, and theability to publish wheels for at least Windows and Mac OS X through thePython Packaging Index, this problem is expected to diminish over time,as users are more regularly able to install pre-built extensions ratherthan needing to build them themselves.

Some of the solutions for installing scientific softwarethat are not yet available as pre-built wheel files may also help withobtaining other binary extensions without needing to build them locally.

Python Openpyxl Introduction

Python provides the Openpyxl module, which is used to deal with Excel files without involving third-party Microsoft application software. By using this module, we can have control over excel without open the application. It is used to perform excel tasks such as read data from excel file, or write data to the excel file, draw some charts, accessing excel sheet, renaming sheet, modification (adding and deleting) in excel sheet, formatting, styling in the sheet, and any other task. Openpyxl is very efficient to perform these tasks for you.

Data scientists often use the Openpyxl to perform different operations such as data copying to data mining as well as data analysis.

Openpyxl Working Process

The Openpyxl library is used to write or read the data in the excel file and many other tasks. An excel file that we use for operation is called Workbook that contains a minimum of one Sheet and a maximum of tens of sheets.

• Sheets consist of Rows (horizontal series) starting from 1 and Columns (vertical series) starting from A.
• Row and column together make a grid and form a cell that may store some data. Data can be of any type, such as numeric, string.
• Openpyxl provides flexibility to read data from the individual cell or write data to it.

Installation of Openpyxl

In the above section, we have discussed the openpyxl briefly and its working process. In order to use Openpyxl, one should have Python 3.7 and openpyxl 2.6.2 installed in the system. Let's start working with openpyxl by installing openpyxl using the following command:

The xlsx is the extension of the XML spreadsheet file. The xlsx file supports macros. Let's understand the basic operation related to the excel file. Consider the following code:

Output:

In the above code, we have written data into the five cells A1, A2, A3, A4, and A5. These cells consist of different types of values. We have imported Workbook class from the openpyxl module. A workbook class is a container that contains all parts of the document.

Here we have defined a new workbook. At least one sheet is always made with a workbook.

We get the location of the active sheet.

We have saved all data to the sample_file.xlsx file using the save() method.

Openpyxl Write Data to Cell

We can add data to the excel file using the following Python code. First, we will import the load_workbook function from the openpyxl module, then create the object of the file and pass filepath as an argument. Consider the following code:

Output:

Openpyxl Append values

Openpyxl provides an append() method, which is used to append the group of values. We can append any type of value. These values are appended at the bottom of the current working sheet. Consider the following code:

Output:

Openpyxl Read Data from cell

We can read the data that we have previously written in the cell. There are two methods to read a cell, firstly we can access it by cell name, and secondly, we can access it by the cell() function. For example, we are reading the data from the sample_file.xlrs file.

Output:

Openpyxl Read multiple cells

We can read the values from the multiple cells. In the following example, we have marks.xlsx named excel file and we will read each cell of file using the range operator. Let's have a look at the following program:

Output:

Openpyxl Iterate by rows

The openpyxl provides the iter_row() function, which is used to read data corresponding to rows. Consider the following example:

Output:

Openpyxl Iterate by Column

The openpyxl provides iter_col() method which return cells from the worksheet as columns. Consider the following example:

Output:

Openpyxl Sheets

As we know that each workbook can have multiple sheets. First, we need to create more than one sheet in a single workbook then we can access those excel sheets using Python. In the following example, we have created a workbook with three sheets:

Output:

It will look like the following image.

Openpyxl filter and sort data

The auto_filter attribute is used to set filtering and sorting conditions. Consider the following code:

Output:

Openpyxl Merging cell

We can merge the cell using the merge_cells() method. When we merge the cells, the top-left one is removed from the worksheet. The openpyxl also provides the unmerged_cells() method to unmerge the cell. Consider the following code:

Output:

The freezing panes are simply mean to freeze an area of worksheet as visible while scrolling to other parts of the worksheet. It is useful feature where we can display the top row or leftmost column on the screen. We can do this by passing the cell name to the freeze_panes variable. To unfreeze all panes, set freeze_panes to 'None'. Consider the following code:

Output:

Run the above code and scroll the worksheet.

Openpyxl formulas

We can write formula into the cell. These formulas are used to perform operations in excel file. After writing in the cell execute it from the workbook. Consider the following example:

Output:

Openpyxl Cell Inverter

The openpyxl cell inverter is used to invert the row and column of the cell in the spreadsheet. For example, the value at 3 rows will be inverted into 5 columns and row at row 5 will invert to column 3 (vice versa). You can see in the following images:

This program is written with the help of nested for loop. First the data structure writes in the sheetData[x][y] for the cell at column x and row y then the newly created spreadsheet in the spreadData[y][x] for the cell at column y and row x.

Adding Chart to Excel File

Charts are effective way to represent the data. Using the charts, it visualizes the data which can be easily untestable. There are various types of chart: pie chart, line chart, bar chart, and so on. We can draw a chart on a spreadsheet using an openpyxl module.

For building any chart on the spreadsheet, we need to define the chart type like BarChart, LineChart, and so on. We also import reference which represents data that is used for the chart. It is important to define what data we want to represent on the chart. Let's understand by the following example:

Output:

In the above code, we have created the sample data and drawn the bar chart corresponding to sample data.

Now we will create the line chart. Consider the following code:

Output:

In the above code, we are used from_rows = True as a parameter, it denotes chart plot row by row instead of the column by column.

Adding Image

Images are not generally used in a spreadsheet but sometimes we can use as per our requirement. We can use an image for the branding purposes or to make the spreadsheet more personal and attractive. For loading an image to spreadsheet, we need to install an additional module called pillow by the following command.
