How to get html of a cell using PHPExcel? - php

Question

I've tried to import an xlsx file to array, but noticed, that it contains simple text whereas if I open it in OpenOffice, I can see some words in the cell are bold.
#items: array:2 [
"url" => "theurl"
"meta_title" => "text with one bold word"
]
Is there a way to get somehow text with <b>one</b> bold word?
PHPExcel wiki says nothing about it. Its valueBinder applies only to csv and html files.

Thanks to Mark Baker. The HTML Writer code helps to create simple converter. Usage:
$richtextService = new RichTextService();
$value = $reader->getActiveSheet()->getCell('F2')->getValue();
$html = $richtextService->getHTML($value); // html in it
And the class:
namespace App\Services;
use PHPExcel_RichText;
use PHPExcel_RichText_Run;
use PHPExcel_Style_Font;
class RichTextService{
/**
* Takes array where of CSS properties / values and converts to CSS stri$
*
* #param array
* #return string
*/
private function assembleCSS($pValue = array())
{
$pairs = array();
foreach ($pValue as $property => $value) {
$pairs[] = $property . ':' . $value;
}
$string = implode('; ', $pairs);
return $string;
}
/**
* Create CSS style (PHPExcel_Style_Font)
*
* #param PHPExcel_Style_Font $pStyle PHPExcel_Style_Font
* #return array
*/
private function createCSSStyleFont(PHPExcel_Style_Font $pStyle)
{
// Construct CSS
$css = array();
// Create CSS
if ($pStyle->getBold()) {
$css['font-weight'] = 'bold';
}
if ($pStyle->getUnderline() != PHPExcel_Style_Font::UNDERLINE_NONE && $pStyle->getStrikethrough()) {
$css['text-decoration'] = 'underline line-through';
} elseif ($pStyle->getUnderline() != PHPExcel_Style_Font::UNDERLINE_NONE) {
$css['text-decoration'] = 'underline';
} elseif ($pStyle->getStrikethrough()) {
$css['text-decoration'] = 'line-through';
}
if ($pStyle->getItalic()) {
$css['font-style'] = 'italic';
}
$css['color'] = '#' . $pStyle->getColor()->getRGB();
$css['font-family'] = '\'' . $pStyle->getName() . '\'';
$css['font-size'] = $pStyle->getSize() . 'pt';
return $css;
}
/**
*
* #param PHPExcel_RichText|string $value
* #return string
*/
public function getHTML($value) {
if(is_string($value)) {
return $value;
}
$cellData = '';
if ($value instanceof PHPExcel_RichText) {
// Loop through rich text elements
$elements = $value->getRichTextElements();
foreach ($elements as $element) {
// Rich text start?
if ($element instanceof PHPExcel_RichText_Run) {
$cellData .= '<span style="' . $this->assembleCSS($this->createCSSStyleFont($element->getFont())) . '">';
if ($element->getFont()->getSuperScript()) {
$cellData .= '<sup>';
} elseif ($element->getFont()->getSubScript()) {
$cellData .= '<sub>';
}
}
// Convert UTF8 data to PCDATA
$cellText = $element->getText();
$cellData .= htmlspecialchars($cellText);
if ($element instanceof PHPExcel_RichText_Run) {
if ($element->getFont()->getSuperScript()) {
$cellData .= '</sup>';
} elseif ($element->getFont()->getSubScript()) {
$cellData .= '</sub>';
}
$cellData .= '</span>';
}
}
}
return str_replace("\n", "<br>\n", $cellData);
}
}

With this small adaptions this solution works with the successor PhpSpreadsheet:
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\RichText;
use PhpOffice\PhpSpreadsheet\RichText\Run;
use PhpOffice\PhpSpreadsheet\Style\Font;
class RichTextService {
/**
* Takes array where of CSS properties / values and converts to CSS stri$
*
* #param array
* #return string
*/
private function assembleCSS($pValue = array())
{
$pairs = array();
foreach ($pValue as $property => $value) {
$pairs[] = $property . ':' . $value;
}
$string = implode('; ', $pairs);
return $string;
}
/**
* Create CSS style (Font)
*
* #param Font $pStyle Font
* #return array
*/
private function createCSSStyleFont(Font $pStyle)
{
// Construct CSS
$css = array();
// Create CSS
if ($pStyle->getBold()) {
$css['font-weight'] = 'bold';
}
if ($pStyle->getUnderline() != Font::UNDERLINE_NONE && $pStyle->getStrikethrough()) {
$css['text-decoration'] = 'underline line-through';
} elseif ($pStyle->getUnderline() != Font::UNDERLINE_NONE) {
$css['text-decoration'] = 'underline';
} elseif ($pStyle->getStrikethrough()) {
$css['text-decoration'] = 'line-through';
}
if ($pStyle->getItalic()) {
$css['font-style'] = 'italic';
}
$css['color'] = '#' . $pStyle->getColor()->getRGB();
$css['font-family'] = '\'' . $pStyle->getName() . '\'';
$css['font-size'] = $pStyle->getSize() . 'pt';
return $css;
}
/**

public function getHTML($value) {

return $value;
}
$cellData = '';
if ($value instanceof PhpOffice\PhpSpreadsheet\RichText\RichText) {
// Loop through rich text elements
$elements = $value->getRichTextElements();
foreach ($elements as $element) {
// Rich text start?
print_r($element);
if ($element instanceof PhpOffice\PhpSpreadsheet\RichText\Run) {
$cellData .= '<span style="' . $this->assembleCSS($this->createCSSStyleFont($element->getFont())) . '">';
if ($element->getFont()->getSuperScript()) {

return str_replace("\n", "<br>\n", $cellData);
