Converting CSV Files to HTML Using PHP and Cloudmersive API

Writing PHP code to convert CSV files to HTML can be challenging, requiring solid PHP skills and understanding of CSV and HTML formats, as well as handling data delimiters and ensuring accurate, efficient conversion.

Fortunately, a free CSV‑to‑HTML conversion API (Cloudmersive) is available, offering a simple and efficient way to boost productivity.

The API can be used with a free Cloudmersive API key that allows up to 800 conversions per month without any commitment.

First, install the Cloudmersive PHP client via Composer:

composer require cloudmersive/cloudmersive_document_convert_api_client

Then, replace the placeholder YOUR_API_KEY with your own key and call the provided CSV‑to‑HTML function.

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

// Configure API key authorization: Apikey
$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"; // \SplFileObject | input file to process

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

With just a few lines of PHP, you can easily convert CSV data into well‑formatted HTML.
