XLSX files are Excel files that use the Office Open XML format, introduced with Microsoft Excel 2007.

XLSX files can contain multiple sheets, and each sheet can contain multiple rows and columns of data. They offer several advantages over the older XLS format.

Key features of XLSX files include:

  • Improved compression, resulting in smaller file sizes
  • Enhanced security features, including password protection and digital signatures
  • Better recovery from file corruption
  • Support for more rows (1,048,576) and columns (16,384) per sheet
  • Compatibility with a wide range of applications and programming languages

XLSX files are based on XML and ZIP technologies, making them more accessible for third-party software to read and write.


Apache Arrow is a cross-language development platform for in-memory data that specifies a standardized language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware like CPUs and GPUs.

Arrow is designed to support complex nested data structures and enables efficient querying and manipulation of specific columns without reading the entire dataset.

Key Features

  • Columnar memory format for flat and hierarchical data
  • Language-agnostic specification
  • Optimized for analytical processing and modern hardware
  • Support for complex nested data structures
  • Efficient zero-copy reads

Use Cases

Apache Arrow is particularly useful in scenarios involving:

  • Big data processing and analytics
  • Machine learning and AI pipelines
  • Data interchange between different systems and languages
  • High-performance computing applications

Its efficient memory layout and standardized format make it an excellent choice for applications requiring fast data processing and interoperability between different tools and languages.
