JavaScript is required for this interactive tool.Static Reference / Engine Logic:const lines = input.value.trim().split('\n'); if(lines.length === 0 || lines[0] === '') { output.textContent = 'Please enter CSV data.'; return; } let html = '<table>\n <thead>\n <tr>\n'; const headers = lines[0].split(','); headers.forEach(h => html += ` <th>${h.trim()}</th>\n`); html += ' </tr>\n </thead>\n <tbody>\n'; for(let i = 1; i < lines.length; i++) { const cols = lines[i].split(','); html += ' <tr>\n'; cols.forEach(c => html += ` <td>${c.trim()}</td>\n`); html += ' </tr>\n'; } html += ' </tbody>\n</table>'; // Render as actual HTML since it's a table generator tool, not just text Content. output.innerHTML = ''; output.insertAdjacentHTML('beforeend', html);
