Convert CSV to HTML in PHP with a Free Cloudmersive API – Step-by-Step Guide

Converting CSV data to HTML with PHP can be challenging because it requires solid PHP skills and understanding of both file formats. This article outlines a practical solution using the free Cloudmersive Document Convert API.

Install the API client

First, install the Cloudmersive PHP client via Composer:

composer require cloudmersive/cloudmersive_document_convert_api_client

Configure the API key

Replace the placeholder YOUR_API_KEY with your free Cloudmersive API key. The configuration code sets the key for subsequent requests.

<?php
require_once(__DIR__ . '/vendor/autoload.php');

// Set API key
$config = Swagger\Client\Configuration::getDefaultConfiguration()
    ->setApiKey('Apikey', 'YOUR_API_KEY');

$apiInstance = new Swagger\Client\Api\ConvertDocumentApi(
    new GuzzleHttp\Client(),
    $config
);

$input_file = "/path/to/inputfile"; // Path to the CSV file

try {
    $result = $apiInstance->convertDocumentCsvToHtml($input_file);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling ConvertDocumentApi->convertDocumentCsvToHtml: ', $e->getMessage(), PHP_EOL;
}
?>

Run the conversion

Executing the script sends the CSV file to the Cloudmersive service, which returns the HTML representation. The free tier allows up to 800 conversions per month without any commitment.

With only a few lines of PHP, developers can reliably convert CSV data into polished HTML output.
