Pandas 读取 Excel 替代方案(不使用 Interop) | IronXL for Python

Excel files are ubiquitous in data analysis and manipulation tasks, offering a convenient way to store and organize tabular data. In Python, there are multiple libraries available for reading Excel files, each with its own set of features and capabilities. Two prominent options are Pandas and IronXL, both offering efficient methods for reading Excel files in Python.

In this article, we'll compare the functionality and performance of Pandas and IronXL to Read Excel files in Python.

Pandas - Open Source Library

Pandas is a powerful open-source data analysis and manipulation library for Python. It introduces the DataFrame data structure, which is a two-dimensional labeled data structure with columns of potentially different types. Pandas offers a wide range of functionalities for data manipulation, including reading and writing data from various sources, such as CSV files, SQL databases, and Excel files.

Some key features of Pandas include:

DataFrame

Pandas introduces the DataFrame data structure, which is essentially a two-dimensional labeled data structure with columns of potentially different types. It's similar to a spreadsheet or SQL table, making it easy to perform operations like filtering, grouping, and aggregation on tabular data.

Data manipulation

Pandas offers a wide range of functions for data manipulation, including merging, reshaping, slicing, indexing, and pivoting data. These operations allow users to clean, transform, and prepare data for analysis or visualization efficiently.

Time series functionality

Pandas provides robust support for working with time series data, including tools for date/time indexing and resampling, and convenient methods for handling missing data and time zone conversion.

Integration with libraries

Pandas can seamlessly collaborate with various Python libraries frequently employed in data analysis and scientific computations, including NumPy, Matplotlib, and Scikit-learn. This interoperability allows users to leverage the strengths of different libraries within a single analysis workflow.

Overall, Pandas is a powerful tool for data manipulation and analysis in Python, and it's widely used in various domains, including finance, economics, biology, and social sciences.

  3. Install OpenPyXL via pip: OpenPyXL is the library that helps read and write Excel files. It is one of the dependencies used by Pandas. When you install Pandas, OpenPyXL is automatically installed if not present already. If somehow it isn't installed, then you can install it using the following command in the terminal:

    pip install openpyxl
    pip install openpyxl
    SHELL

Installing IronXL

To install IronXL in a Python project, follow these steps:

  1. Ensure Prerequisites: Before installing IronXL, make sure you have the necessary prerequisites installed on your system.

    .NET 6.0 SDK: IronXL relies on the IronXL .NET library, specifically .NET 6.0, as its underlying technology. Ensure that you have the .NET 6.0 SDK installed on your machine. You can download it from the official .NET website.

  2. Open Command Prompt or Terminal: Do the same as before.
  3. Install IronXL via pip: IronXL can be installed using the pip package manager. Run the following command:

    
    :ProductInstall
    W```
    
    This command will collect, download, and install the IronXL library and its dependencies from the Python Package Index (PyPI).

Reading Excel Files using Pandas and IronXL

As we have set up everything, we'll move on to reading Excel files using both libraries. The demo Excel file that we are going to read has the following values with header rows as Name, Marks, and Res:

Using Pandas

Step 1

Import the Pandas library and use the read_excel() function to read column data from the Excel file.

import pandas as pd

# Read the Excel file
df = pd.read_excel("file.xlsx")
import pandas as pd

# Read the Excel file
df = pd.read_excel("file.xlsx")
PYTHON

When using Pandas' read_excel() function, you can specify several options for displaying as required:

  • header: Specifies which row in the Excel file to use as column names. You can set it to None to indicate that there is no header row, or you can provide an integer indicating the row number. If skipped, the headers are set to True by default, and the first row positions get displayed as header row labels.
  • index_col: Specifies which column or columns to use as the index of the DataFrame. You can pass a single column name or column index, or you can pass a list of column names or column indices to create a MultiIndex.

  • sheet_name: Specifies the sheet(s) to read from the Excel file. You can provide the sheet name as a string or an integer indicating the zero-indexed sheet positions.
  • usecols: Specifies which columns to read from the Excel file. You can pass either a single column name or a column index, or you could pass a list of column names or column indices to read specific columns.
  • dtype: Specifies the data types for columns. You can pass a dictionary where keys are column names or column indices and values are the desired data types.
  • converters: Specifies functions to apply to columns for custom parsing. You can pass a dictionary where keys are column names or column indices and values are functions.

  • na_values: Specifies additional strings to recognize as NaN (Not a Number) values. You can pass a list of strings to be treated as NaN.
  • parse_dates: Specifies which columns to parse as dates. You can pass either a single column name or a column index, or you could pass a list of column names or indices to parse as dates.
  • date_parser: Specifies a function to use for parsing dates. You can pass a function that accepts a string and returns a datetime object.
  • skiprows: Specifies the number of rows to skip at the beginning of the Excel file.

These options provide flexibility when reading Excel files with Pandas, allowing you to customize the reading process according to your specific requirements.

Step 2

Display the contents of the DataFrame.

print(df)
print(df)
PYTHON

Here is the output of the above code:

Using IronXL

Step 1: Import the IronXL library and use the WorkBook.Load() method to load the Excel file. In the Load method parameter, you can pass the valid file URL, local file path object, or filename if it is in the same directory as the script.

from ironxl import WorkBook

# Load the Excel file as a WorkBook object
workbook = WorkBook.Load("file.xlsx")
from ironxl import WorkBook

# Load the Excel file as a WorkBook object
workbook = WorkBook.Load("file.xlsx")
PYTHON

Step 2: With IronXL, you can access multiple sheets and print column labels. Access the worksheets and cells to read the column-stored data. The cells can be of any data type like numeric columns or string columns. The cell values can be converted to int by parsing string columns to numeric values using the IntValue property and vice versa.

# Access the first worksheet
worksheet = workbook.DefaultWorkSheet

# Select a specific cell and return the converted value
cell_value = worksheet["A2"].IntValue
print(cell_value)

# Read from the entire worksheet and print each cell's address and value
for cell in worksheet:
    print(f"Cell {cell.AddressString} has value '{cell.Text}'")
# Access the first worksheet
worksheet = workbook.DefaultWorkSheet

# Select a specific cell and return the converted value
cell_value = worksheet["A2"].IntValue
print(cell_value)

# Read from the entire worksheet and print each cell's address and value
for cell in worksheet:
    print(f"Cell {cell.AddressString} has value '{cell.Text}'")
PYTHON

Here is the output of the above code with a proper display format showcasing the versatility of IronXL:
