What is XHTML?

XHTML, or Extensible Hypertext Markup Language, is a web coding standard that combines the strengths of HTML and XML. It is stricter in syntax than HTML and is designed to be more readable by machines, ensuring better compatibility and accessibility. XHTML is often needed when creating websites that require a higher level of compliance with web standards, especially for mobile and modern web applications.

Improper Tag Closure

XHTML requires that all tags be properly closed. Inconsistent tag usage from Excel may lead to rendering issues in browsers.

Attribute Case Sensitivity

XHTML attributes are case-sensitive. Excel-generated HTML may use attributes in incorrect casing, resulting in validation errors.

Missing DOCTYPE Declaration

When converting to XHTML, it is essential to include a proper DOCTYPE declaration to ensure the document is processed correctly across different browsers.

Entities for Special Characters

XHTML requires some special characters to be represented by entities (e.g., & becomes &). Excel output may not always conform, leading to display issues.

What are the differences between XLSX and XLS?

File Format

XLSX is the modern file format used by Microsoft Excel, introduced with Excel 2007, and is based on the Open XML standard. In contrast, XLS is the older binary file format used by earlier versions of Excel up to 2003.

File Size

XLSX files are generally smaller in size compared to XLS files because they use Zipping compression, making it more efficient for storage and sharing.

Data Capacity

XLSX supports a significantly larger amount of data, allowing for up to 1,048,576 rows and 16,384 columns per worksheet, while XLS is limited to 65,536 rows and 256 columns.

Features and Functions

XLSX files support newer features and functions available in Excel 2007 and later versions, such as improved charting tools, Sparklines, and enhanced formulas. XLS files do not have access to these advanced features.
