XLSX

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

Like XLS files, XLSX files can have 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:

Better 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
Works with a wide range of applications and programming languages

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

Parquet

Parquet is a columnar storage file format designed for efficiency with big data processing frameworks like Apache Hadoop and Spark.

Technical Details

Parquet organizes data by columns rather than rows, which enables better compression and more efficient queries for analytical workloads. It supports nested data structures and is optimized for handling complex data.
