What is HTML?

HTML (HyperText Markup Language) is the standard markup language used to create and design documents on the World Wide Web. HTML structures the content on the web, including text, images, links, and other multimedia, making it essential for web development and design.

Loss of Formatting

When converting Excel to HTML, the original formatting such as fonts, colors, and cell styles may not be preserved, leading to a plain and less visually appealing output.

Data Overflow

Excel sheets can contain a lot of data, and when converting to HTML, large datasets may not fit well within the web page layout, causing overflow or readability issues.

Link and Reference Issues

Links and references within Excel (such as hyperlinks or formulas referencing other cells) may not convert properly to HTML, which can disrupt navigation and data integrity.

Compatibility Problems

Different web browsers may render HTML documents generated from Excel differently, leading to inconsistencies in how the content is displayed, which can affect user experience.
