What is the difference between XLS and XLSX file? How to Open and Share them

In today’s digital world, Excel files are one of the most widely used formats for data storage, analysis, and sharing. If you’ve ever worked with spreadsheets, chances are you’ve encountered both XLS and XLSX files. But what’s the difference between these two formats, and why should you care?

In this article, we will walk you through the essentials of XLS vs. XLSX, explain the key differences, and show you how you can easily open, read, and share these files with Tiiny Host. Let’s dive in!

What Are XLS and XLSX?

Both XLS and XLSX are file formats used by Microsoft Excel, a popular spreadsheet software. While they serve the same general purpose—storing data in a tabular format—there are important differences between them.

  • XLS (Excel Spreadsheet) : This is the older format used by Excel. It was introduced in 1985 with Excel 2.0 and continued to be the standard until Excel 2007. XLS files are based on a binary format, meaning the data is stored in a compact, non-text format that can only be opened with software that understands it, like Excel or other spreadsheet applications.
  • XLSX (Excel Open XML Spreadsheet) : Starting with Excel 2007, Microsoft introduced the XLSX format, which is based on the open XML standard. Unlike XLS, XLSX files store data in a compressed XML format, making it more accessible and versatile. These files are typically smaller in size and more easily integrated with other software tools.

Both XLS and XLSX files, along with CSV files, are commonly used for data analysis, reporting, and creating graphical representations of data. Whether you’re creating annual reports or visualizing complex datasets, these file formats are valuable tools for both professionals and casual users alike.

Key Differences Between XLS and XLSX

Let’s break down the main differences to help you understand how they affect your work with Excel files:

  • File Size: XLS files tend to be larger due to their binary format, whereas XLSX files are smaller in size because of the compressed XML structure.
  • Compatibility: XLS files have limited compatibility with older software and versions of Excel, while XLSX files are more compatible with modern tools, including Excel 2007 and later, as well as open-source software like Google Sheets and LibreOffice.
  • Features: XLS does not support newer Excel features introduced after Excel 2007, such as more rows and columns or improved charting, whereas XLSX supports all these modern features.
  • Security: XLS files have fewer security features, while XLSX offers enhanced security options, including the ability to set passwords and disable macros for better protection.
  • Readability: XLS files are harder to read programmatically because of their binary format, but XLSX files, based on XML, are easier for other software to parse and manipulate.
  • Flexibility: XLS files offer less flexibility for integration with third-party apps, whereas XLSX files are more flexible and easily integrated into modern tools and workflows.

Why Choose XLSX Over XLS?

Given the differences above, it’s clear that the XLSX format offers several advantages over XLS. Whether you are working on a personal project or collaborating in a professional setting, XLSX is the way to go. Here’s why:

  • Smaller file sizes make it easier to share and store, particularly when you’re dealing with large files.
  • Better compatibility with modern tools and software allows for more seamless integration, especially when working with cloud-based applications like Google Sheets.
  • Advanced features like enhanced charting, formatting options, and the ability to handle more rows and columns.
  • Increased security ensures that your data is protected with modern encryption methods.
