Introduction

Spreadsheets are widely used for data manipulation and analysis in today’s world. Excel, being one of the most powerful tools for spreadsheet management, is used by millions of people across the globe. Python, on the other hand, is a powerful programming language that has been gaining popularity due to its versatility and ease of use. In this article, we will discuss how to effortlessly add rows to Excel using Openpyxl in Python.

Overview of Openpyxl

Openpyxl is a library in Python used for reading and writing Excel files. It is relatively easy to use and is considered one of the best libraries available for handling Excel files in Python. Openpyxl is compatible with Microsoft Excel 2007 onwards for both .xlsx and .xlsm formats. It allows a user to read and write cells, rows, columns, charts, images, comments, and worksheets.

Basic Code Implementation

The following code shows how you can create an Excel file with openpyxl:

“`pythonimport openpyxlwb = openpyxl.Workbook()wb.save(‘example.xlsx’)“`

To add a new worksheet in the Excel file created above, we can use the following code:

“`pythonimport openpyxlwb = openpyxl.Workbook()ws = wb.create_sheet(new_worksheet)wb.save(‘example.xlsx’)“`

Adding Rows to an Excel File

Now that we know how to create a basic Excel file and add a new worksheet in it, let’s move on to how we can add rows to an existing worksheet. The following code shows how to add a single row to a worksheet:

“`pythonimport openpyxlwb = openpyxl.load_workbook(‘example.xlsx’)ws = wb.activews.append([1, 2, 3, 4])wb.save(‘example.xlsx’)“`

Adding Multiple Rows at Once

Adding multiple rows to an Excel file can be tricky and time-consuming, especially if you have a large number of rows to add. Openpyxl provides a built-in feature where you can append multiple values at once using a list of lists:

“`pythonimport openpyxlwb = openpyxl.load_workbook(‘example.xlsx’)ws = wb.activedata = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]for row in data: ws.append(row)wb.save(‘example.xlsx’)“`

Adding Rows Above the Existing Rows

Sometimes, we need to add rows above the existing rows. Openpyxl provides the `insert_rows()` function that allows us to add rows above existing rows:

“`pythonimport openpyxlwb = openpyxl.load_workbook(‘example.xlsx’)ws = wb.active# Insert 2 rows above row 3ws.insert_rows(idx=3, amount=2)# Populate the cellsws.cell(row=3, column=1).value = ‘New Row 1’ws.cell(row=4, column=1).value = ‘New Row 2’wb.save(‘example.xlsx’)“`

Comparison with Other Libraries

There are several libraries available to handle Excel files in Python. Let’s compare Openpyxl with some of the popular libraries:

Library	Advantages	Disadvantages
Openpyxl	Easy to use, compatible with Excel 2007+, excellent documentation	Can be slow for large data sets, requires Microsoft Excel to be installed on the system
XlsxWriter	Fast, no external dependencies, supports charts and images	Does not support reading or modifying existing files, limited formatting options
Pandas	Fast, easy to use, powerful data manipulation features	Not a dedicated Excel library, requires additional steps to export data to Excel format

Conclusion

Adding rows to an Excel file can be challenging, especially when dealing with large data sets. Openpyxl provides an effective solution for adding rows to an existing worksheet, making it easier to handle Excel files in Python. In this article, we have discussed how to create an Excel file, add a new worksheet, and add rows to an existing worksheet using Openpyxl. We have also compared Openpyxl with other popular libraries available in Python. Overall, Openpyxl is a reliable library that can simplify your spreadsheet management tasks.

• Is it possible to add multiple rows at once in Openpyxl?
• What is the syntax for adding a row in Openpyxl?
• Can I add rows to a specific sheet in an Excel file using Openpyxl?

1. To add rows to an Excel file using Openpyxl, you can use the append() method of the worksheet object. This method allows you to add a single row at a time to the end of your worksheet.
2. Yes, it is possible to add multiple rows at once in Openpyxl. You can do this by creating a list of lists, where each inner list contains the values for a single row. Then, you can use the append() method with this list of lists as an argument to add all the rows at once.
3. The syntax for adding a row in Openpyxl is as follows: worksheet.append([value1, value2, value3]) Here, worksheet is the object representing the worksheet you want to add a row to, and value1, value2, and value3 are the values you want to add to the new row.
4. Yes, you can add rows to a specific sheet in an Excel file using Openpyxl. To do this, you first need to select the sheet you want to add rows to using the workbook object’s active property or by specifying the sheet name. Then, you can use the append() method to add rows to the selected sheet.
