Now we need to obtain our personalized API credentials(i.e. Client ID and Client Secret). Please follow the instructions specified in this short tutorial explaining the details on how to get the API credentials.

Convert Comma Delimited File to HTML in C# .NET

Let’s explore the details of using GroupDocs.Conversion Cloud for .NET, as it ensures high-fidelity conversion results, preserving the structure, formatting, and data integrity of the original CSV files.

Create an instance of Configuration class where we pass client credentials as arguments.

var configurations = new Configuration(clientId, clientSecret1);

Initialize the ConvertApi where we pass Configuration object as an input argument.

var apiInstance = new ConvertApi(configurations);

Upload the input CSV file to the cloud storage.

fileUpload.UploadFile(new UploadFileRequest("input.csv", stream));

Create an instance ConvertSettings where we specify the name for input CSV, resultant format as html and the name for output HTML as arguments.

var settings = new ConvertSettings{...}

Call the ConvertDocumentRequest API to convert CSV to HTML and save the resultant HTML to the cloud storage.

var response = apiInstance.ConvertDocument(new ConvertDocumentRequest(settings));

	// More examples over https://github.com/groupdocs-conversion-cloud/groupdocs-conversion-cloud-dotnet
	// Obtain your API credentials
	string clientId = "4bdefca3-f08c-4088-9ca0-55c38f4b7f22";
	string clientSecret1 = "a43c8b4365246a062688a259abe5b469";

	// Create an instance of the Configuration class and initialize it with the Client ID & Client Secret.
	var configurations = new GroupDocs.Conversion.Cloud.Sdk.Client.Configuration(clientId, clientSecret1);
	// Define the value of ApiBaseUrl to set the base url for CSV to HTML conversion API.
	configuration.ApiBaseUrl = "https://api.groupdocs.cloud";

	// Initialize an instance of the ConvertApi class with the object of the Configuration class.
	var apiInstance = new GroupDocs.Conversion.Cloud.Sdk.Api.ConvertApi(configurations);

	// load the input Excel workbook from local drive
	using (var stream = System.IO.File.OpenRead("sourceFile.csv"))
	{
	// create an instance of FileApi
	var fileUpload = new FileApi(configurations);
	// upload the input CSV to cloud storage
	fileUpload.UploadFile(new UploadFileRequest("input.csv", stream));

	// create ConvertSettings where we define the name of source CSV and the name for resultant HTML file
	var settings = new ConvertSettings
	{
	StorageName = "internal",
	FilePath = "input.csv",
	Format = "html",
	OutputPath = "ConvertedFile.html"
	};

	// Invoke the ConvertDocument method for CSV to HTML conversion.
	var response = apiInstance.ConvertDocument(new GroupDocs.Conversion.Cloud.Sdk.Model.Requests.ConvertDocumentRequest(settings));
	if (response != null && response.Equals("OK"))
	{
	// print success message
	Console.WriteLine("The Web page successfully saved as Excel workbook !");
	}
	}

The input CSV file used in the above example can be downloaded from input.csv.

CSV to HTML Conversion using cURL Commands

You may also leverage the power and flexibility of using GroupDocs.Conversion Cloud and cURL commands for CSV files to HTML conversion. This approach offers a convenient and efficient way to transform CSV data into HTML documents, catering to various use cases such as data presentation, web publishing, and more. So, let’s explore the details on how we can initiate and control the conversion process seamlessly either through command-line interface or within the scripts.

The first step is to generate a JWT access token based on client credentials and once we have generated the JWT token, please execute the following cURL command to convert CSV to HTML table and save the resultant HTML in cloud storage.

curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"internal\",  \"FilePath\": \"{sourceFile}\",  \"Format\": \"html\",  \"LoadOptions\": {    \"Format\": \"csv\"  },  \"OutputPath\": \"{resultantFile}\"}" -v

Please replace sourceFile with the name of input CSV file, resultantFile with the name of resultant HTML and accessToken with personalized JWT access token.

Now, instead of saving the resultant HTML to Cloud storage, you may also save it to the local drive. Please try using following cURL command:

curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"internal\",  \"FilePath\": \"{sourceFile}\",  \"Format\": \"html\",  \"LoadOptions\": {    \"Format\": \"csv\"  }}" \
-o "ConvertedFile.html"
