Whether you’re dealing with complex spreadsheets or straightforward data sets, the SDK ensures efficiency, accuracy, and ease of integration into your .NET applications. So in this section, we are going to convert an XLS to JSON format using C# .NET.

CellsApi cellsInstance = new CellsApi(clientID, clientSecret);

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

using (var file = System.IO.File.OpenRead(input_CSV))

Read the content of input Excel workbook into stream instance.

cellsInstance.CellsWorkbookPutConvertWorkbook(file, format: "JSON", outPath: resultant_file);

Finally, call the API to convert Excel workbook to JSON and upload the resultant file to cloud storage.

Converting XLSX to JSON using cURL Commands

Another interesting option for seamless conversion of XLSX to JSON, that can easily integrates into your workflow is a powerful combination of Aspose.Cells Cloud and cURL commands. The flexibility provided by Aspose.Cells Cloud API allows you to interact with the service through simple cURL commands, offering a scriptable solution that transcends platforms.

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

curl -v "" \
 -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 an XLSX to JSON format. Please note that the following request method requires the input Excel workbook to be already available in the cloud storage.

curl -v "{sourceFile}?format=JSON&isAutoFit=true&onlySaveTable=true&outPath={output}&checkExcelRestriction=true" \
-X GET \
-H  "accept: application/json" \
-H  "authorization: Bearer {accessToken}" \
-d {}

Replace sourceFile with the name of source Excel workbook, output with the name of resultant JSON file and accessToken with a JWT access token generated above.


In conclusion, the capability to convert XLSX to JSON either using Aspose.Cells Cloud SDK for .NET or by using Aspose.Cells Cloud, coupled with cURL commands, stands as a fundamental asset in modern data processing workflows. This feature not only bridges the gap between Excel and JSON, but also unlocks a realm of possibilities for seamless integration and data interchange. Nonetheless, this feature also empowers you to adapt to evolving data requirements, streamline collaboration, and enhance the versatility of their applications.
