Generating HTML tables from CSV is useful for embedding tabular data in web pages, documentation, and content management systems. This tool converts CSV data into either standard HTML <table> markup or MediaWiki table syntax. The standard HTML output includes proper <table>, <thead>, <tbody>, <tr>, <th>, and <td> elements with optional CSS class attributes for styling. The MediaWiki output uses pipe-delimited wiki table syntax for direct pasting into Wikipedia, MediaWiki, or DokuWiki pages. You can configure the input delimiter, toggle whether the first row contains headers, and set a custom CSS class for the table element. The converter produces clean, semantic HTML that validates against the HTML5 specification. All processing happens in your browser using PapaParse for CSV parsing and custom HTML generation logic. The output is ready for copy-paste into any HTML editor, CMS, or documentation platform.
