What it is

Openpyxl is a powerful library that allows developers to read from and write to Excel files using Python, making it an essential tool for data manipulation and analysis tasks involving Excel spreadsheets.

Openpyxl stands out for its simplicity and efficiency in handling Excel files directly from Python code without the need for Microsoft Office or other proprietary software.

When it fits — and when it doesn’t

A good fit for

  • Developers who need to automate tasks involving Excel files without requiring Microsoft Office installed

  • Data scientists working with datasets stored in Excel format for analysis and reporting

  • Automation scripts that require reading from or writing to Excel spreadsheets

Look elsewhere if

  • Projects requiring real-time collaboration features within Excel documents

  • Users who need advanced Excel functionalities not supported by openpyxl, such as macros execution

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited documentation and examples

    The official documentation lacks comprehensive examples and explanations, making it difficult to understand advanced usage without trial and error or external resources.

  2. 02

    Performance issues with large Excel files

    Openpyxl can be slow when processing very large Excel files due to its in-memory handling of data, which may lead to high memory usage and long processing times.

  3. 03

    Complex setup for advanced features like charts and formatting

    Creating complex Excel features such as charts or rich text formatting requires a deep understanding of the library's API, which can be cumbersome to set up correctly.

What it does well

  • Read and write Excel files (.xlsx, .xlsm, .xltx, .xltm)

  • Support for rich text formatting

  • Ability to create charts within Excel spreadsheets

  • Support for named ranges
