Excel files remain one of the most popular formats for managing structured data. In Python, the pandas DataFrame is the go-to structure for organizing and analyzing that data efficiently. Once converted into a DataFrame, Excel data can be seamlessly combined with databases, APIs, or machine learning models for deeper analysis and insights. In this article, we’ll explore practical ways to convert Excel to pandas DataFrames with clear examples to help you get started.

What is a Pandas DataFrame?

A DataFrame is a 2D data structure provided by the pandas library. It looks similar to an Excel spreadsheet with rows and columns. Each column can hold different data types, such as strings, integers, or floats.

DataFrames are ideal for:

  • Importing and cleaning data.
  • Performing mathematical operations.
  • Filtering, grouping, and aggregating data.
  • Exporting results to Excel, CSV, or databases.

When you convert Excel files into DataFrames, you can immediately apply powerful pandas operations for analysis.

Python Library to Convert Excel to Pandas DataFrame

Aspose.Cells for Python via .NET is often considered the best Python Excel library for developers who need more than basic spreadsheet handling. It lets you create, read, edit, and convert Excel files programmatically without installing Microsoft Excel.

For DataFrame conversions, this library shines because it fully supports advanced Excel features such as formulas, merged cells, charts, pivot tables, and conditional formatting. It works with multiple formats, including XLS, XLSX, XLSB, ODS, CSV, and JSON.

When you use Aspose.Cells to bring Excel data into pandas, you get a smooth conversion into DataFrames with high fidelity. This means your Excel structure, formatting, and values remain accurate, while pandas gives you the tools to analyze and transform that data efficiently.

Convert Excel to Pandas DataFrame

You can create a new spreadsheet, generate data programmatically, and convert Excel to a pandas DataFrame in Python. This gives you full control over the structure of the file while making it ready for immediate analysis in pandas.

Follow the steps below to convert Excel to a Pandas DataFrame:

  1. Create an instance of the Workbook class.
  2. Access the first worksheet and its cells.
  3. Add values to the worksheet cells.
  4. Extract rows and headers.
  5. Convert the extracted data into a pandas DataFrame.

The following Python code example demonstrates how to convert Excel to a pandas DataFrame:

Output

      Name  Age           City
0    Alice   25       New York
1      Bob   30  San Francisco
2  Charlie   35    Los Angeles

Convert an Existing Excel File to Pandas DataFrame

If you already have an Excel file, you can load it and convert Excel to a pandas DataFrame in Python directly. This allows you to preserve the original sheet structure while working with the data more efficiently in pandas.

Follow the steps below to load and convert an existing Excel file into a Pandas DataFrame:

  1. Open an existing Excel file using the Workbook class.
  2. Select a worksheet by name or index.
  3. Read all rows and columns.
  4. Extract headers if available.
  5. Convert the result into a pandas DataFrame.

The following Python code shows how to convert an existing Excel file into a pandas DataFrame:
