Convert XLSX to Excel

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.

Microsoft Excel is a powerful spreadsheet application developed by Microsoft for Windows, macOS, Android, and iOS. It offers calculation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).

Excel files can have multiple sheets, and each sheet can contain multiple rows and columns of data. Excel supports various file formats, including XLS, XLSX, and CSV.

Key features of Microsoft Excel include:

• Data analysis tools like sorting, filtering, and conditional formatting
• Ability to create complex formulas and use built-in functions
• Charting and graphing capabilities for data visualization
• Pivot tables for summarizing and analyzing large datasets
