Convert XLSX to Markdown Table

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.

Markdown is a lightweight markup language with plain-text formatting syntax. It's designed to be easy to read, write, and convert to HTML and other formats.

Key features of Markdown include:

• Simple syntax for headings, lists, links, and emphasis
• Support for inline HTML
• Easy to learn and use, even for non-technical users
• Widely supported across various platforms and applications

Markdown is commonly used for:

• Documentation and README files
• Forum and blog posts
• Note-taking and writing
• Creating content for static site generators

While the core syntax is standardized, there are several flavors of Markdown with extended features, such as GitHub Flavored Markdown (GFM) and CommonMark.
