<?php

require 'vendor/autoload.php';

use \PhpOffice\PhpSpreadsheet\IOFactory;
use \PhpOffice\PhpSpreadsheet\Writer\Html;

// Load the workbook, keeping styles so the HTML can carry them.
$spreadsheet = IOFactory::load('sales.xlsx');

$writer = new Html($spreadsheet);

// Write every sheet, not just the active one.
$writer->writeAllSheets();

// Put the CSS on each element instead of in a <style> block, so the
// table survives being pasted into a page or an email.
$writer->setUseInlineCss(true);

// A whole HTML document: <html>, <head>, the styles, and the tables.
$writer->save('sales.html');

// Just the <table> markup, for dropping into a page you already have.
$writer->setSheetIndex(0);
$tableOnly = $writer->generateSheetData();

file_put_contents('table-only.html', $tableOnly);

echo 'Done. Wrote sales.html (' . strlen(file_get_contents('sales.html')) . " bytes, all sheets)\n";
echo 'and table-only.html (' . strlen($tableOnly) . " bytes, the table markup alone).\n";
