Understanding XLS and XLSX Formats

The XLS format is a binary file format used by Microsoft Excel prior to 2007. It is less efficient in terms of file size and lacks some of the advanced features available in the XLSX format. On the other hand, XLSX is an XML-based format introduced with Excel 2007, providing better data recovery and compression.

Key Differences Between XLS and XLSX

• File Structure: XLS files are binary, whereas XLSX files are XML-based.
• File Size: XLSX files are generally smaller due to better compression.
• Features: XLSX supports more advanced features, such as improved charts and tables.

Benefits of Converting XLS to XLSX

Converting your files from XLS to XLSX offers numerous advantages:

• Enhanced Compatibility: XLSX files are supported by newer versions of Excel and other spreadsheet applications.
• Improved Performance: XLSX files load faster and can handle larger data sets more efficiently.
• Data Recovery: The XML structure of XLSX files makes it easier to recover corrupted data.

How to Convert XLS to XLSX Using Microsoft Excel

One of the easiest ways to convert XLS files to XLSX is by using Microsoft Excel itself. Follow these steps:

1. Open the XLS file in Microsoft Excel.
2. Click on "File" in the top menu.
3. Select "Save As" and choose the desired location.
4. In the "Save as type" dropdown menu, select "Excel Workbook (*.xlsx)".
5. Click "Save".
