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 XLSM?

File Extension

XLSX is the standard file format for Excel workbooks that do not contain macros, while XLSM is the format used for workbooks that include macros.

Macro Support

XLSX files cannot store macros, making them safer for users who want to avoid running potentially harmful code. In contrast, XLSM files can harbor macros, allowing for automated tasks and advanced functionalities.

File Size

Generally, XLSM files may have a larger file size compared to XLSX files because they store macro information in addition to regular data, which can increase complexity.

Processing Speed

Workbooks saved in the XLSX format tend to open and process faster than XLSM files since they do not have to load any macro-enabled content, possibly improving performance for users not utilizing macros.
