Convert Excel to HTML in C# .NET

In order to display MS Excel online, the easiest and simple procedure is to transform the Microsoft Excel online to HTML format. This section explains the details on how we can accomplish this feature using C# .NET.

CellsApi cellsInstance = new CellsApi(clientID, clientSecret);

Create an object of CellsApi class where we pass client credentials as arguments.

 cellsInstance.UploadFile("sourceFile.xls", inputFile);

Upload the input Excel workbook to cloud storage.

var response = cellsInstance.CellsWorkbookGetWorkbook("sourceFile.xls", null, format: "HTML", isAutoFit: true, null, null, null, "resultant.html", null);

Call the API to initiate the Excel to HTML conversion operation. After successful operation, the resultant HTML is stored in cloud storage.

The input Excel workbook and the resultant HTML generated in the above example can be downloaded from:

After downloading the resultant HTML, please rename the extension to .html, because due to security reasons, the file with .html extension could not be uploaded.

XLS to HTML using cURL Commands

Aspose.Cells Cloud offers a cloud-based environment where you can leverage its robust API to perform various Excel operations, including the transformation of Excel data into HTML. When it’s coupled with cURL commands, this process becomes scriptable and adaptable, allowing for easy integration into various development environments. This method not only simplifies the integration of Excel to HTML conversion into your workflow, but also ensures a consistent and reliable process.

The first step in this approach is to generate a JWT access token using the following command:

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=921363a8-b195-426c-85f7-7d458b112383&client_secret=2bf81fca2f3ca1790e405c904b94d233" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Now, please execute the following command to convert XLS to HTML online. This method expects the input Excel to be already available in cloud storage and after conversion, the resultant HTML is also stored in cloud storage.

curl -v "https://api.aspose.cloud/v3.0/cells/{sourceFile}?format=HTML&isAutoFit=true&onlySaveTable=false&outPath={Resultant}&checkExcelRestriction=true&pageWideFitOnPerSheet=true&pageTallFitOnPerSheet=true" \
-X GET \
-H  "accept: application/json" \
-H  "authorization: Bearer {accessToken}"

Replace sourceFile with the name of input Excel workbook available in cloud storage, Resultant with the name of resultant HTML to be generated andaccessToken with a JWT access token generated above.

In case we need to save the resultant HTML on local drive, please use the following cURL command. Notice we have skipped the output file name in the GET request and have used -o argument to save the output on local drive.

curl -v "https://api.aspose.cloud/v3.0/cells/{sourceFile}?format=HTML&isAutoFit=true&onlySaveTable=false&checkExcelRestriction=true&pageWideFitOnPerSheet=true&pageTallFitOnPerSheet=true" \
-X GET \
-H  "accept: application/json" \
-H  "authorization: Bearer {accessToken}" \
-o "myOutput.html"


In conclusion, the conversion of Excel to HTML is marked by two versatile approaches, i.e. leveraging the Aspose.Cells Cloud SDK for .NET and harnessing the power of cURL commands with Aspose.Cells Cloud API. So , whether you opt for the comprehensive toolkit and granular control offered by the SDK or the scriptable efficiency and cross-platform compatibility of cURL commands, both approaches effortlessly export Excel data into responsive and visually appealing HTML files.
