The difference between XLS and HTML formats

A simple overview of the features and benefits of the formats

What is XLS?

XLS is a binary spreadsheet format developed by Microsoft for Excel. It was the standard file type before being replaced by XLSX in 2007. XLS files store data in numbered cells organized into columns and rows, supporting formulas, charts, macros, and rich text formatting. The format remains widely used for budgeting, reporting, and data analysis. Despite being a legacy format, XLS files are still compatible with modern versions of Excel, Google Sheets, Apple Numbers, and LibreOffice Calc.

What is HTML?

HTML (HyperText Markup Language) is an international open standard used to create structured web pages and formatted emails. HTML files use command tags in angular brackets to define page elements such as headings, paragraphs, links, images, and tables. Browsers like Chrome, Firefox, Safari, and Edge process the HTML code to display content as intended, while the tags remain hidden from the user. HTML files can be previewed in any browser, and the source code can be viewed or edited using any text editor.
