What Is CSV to HTML Table?

All content is HTML-entity escaped to prevent XSS and rendering issues. The output is clean, indented HTML that you can paste directly into web pages, blog posts, documentation, or content management systems. This tool is perfect for quickly publishing tabular data on the web without manual HTML coding.

Technical Guide

The converter generates standard HTML5 table markup with semantic elements. The first CSV row becomes th elements within a thead section. Subsequent rows become td elements within tbody rows.

All cell content is escaped using HTML entities: & becomes &, < becomes <, > becomes >, and " becomes ". This prevents cross-site scripting (XSS) vulnerabilities and ensures special characters display correctly in browsers.

The output HTML is indented with 2 spaces per level for readability. The table element has no inline styles — you can apply your own CSS for styling. The structure follows accessibility best practices with th elements in thead for screen readers.

For styling, wrap the table in a div with overflow-x: auto for responsive horizontal scrolling on mobile devices.
