Writing PHP code to convert our CSV files to HTML can be a bit of a challenge.

Thankfully, to make our conversions consistently quicker and easier, we can simply take advantage of a free CSV to HTML conversion API.

We can structure our API calls using the complementary, ready-to-run PHP code examples provided below, and we can make up to 800 conversions per month (with zero commitments) using a free Cloudmersive API key.

First, we need to execute the following command to install the PHP client:

composer require cloudmersive/cloudmersive_document_convert_api_client

Right after that, we can call the CSV to HTML function using the following code. We can replace the ‘YOUR_API_KEY’ placeholder string in the $config snippet with our own free API key:

<?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 perform the operation on.

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

That’s all there is to it — now we can easily convert our CSV data to HTML format using minimal PHP code.
