C# and VB.NET Code to Split Worksheets of an Excel Workbook to TIFF or PNG in Cloud

This technical tip shows how developers can split worksheets of a workbook to a separate workbook, TIFF, PNG or any supported image format in the cloud.  This example allows you to split all or specific worksheets of a workbook file and save each worksheet as a new workbook, TIFF or any supported image format using Aspose.Cells for Cloud API in your applications. You can use our REST API with any language: .NET, Java, PHP, Ruby, Rails, Python, jQuery and many more. Some of the code samples are provided for the above languages.

Please take a look over the following code snippet to Split all Worksheets to PNGs

[C# Code]

AsposeApp.AppSID  = "77***********************************";
AsposeApp.AppKey = "9a*******************************";
string outputPath = "C:\\TempFiles\\";

//build URI to split workbook
string strURI = "http://api.aspose.com/v1.1/cells/Sample.xlsx/split?format=png";
//sign URI
string signedURI = Utils.Sign(strURI);
StreamReader reader = new StreamReader(Utils.ProcessCommand(signedURI, "POST"));
//further process JSON response
string strJSON = reader.ReadToEnd();
//Parse the json string to JObject
JObject parsedJSON = JObject.Parse(strJSON);
SplitWorkbookResponse responseStream = JsonConvert.DeserializeObject<SplitWorkbookResponse>(parsedJSON.ToString());

foreach (DocumentResponse splitSheet in responseStream.Result.Documents)
{
    string splitFileName = System.IO.Path.GetFileName(splitSheet.link.Href);
    //build URI to download split worksheets
    strURI = "http://api.aspose.com/v1.1/storage/file/" + splitFileName;
    //sign URI
    signedURI = Utils.Sign(strURI);
    //save split worksheets
    using (Stream fileStream = System.IO.File.OpenWrite(outputPath + splitFileName))
    {
        Utils.CopyStream(Utils.ProcessCommand(signedURI, "GET"), fileStream);
    }
}

    // class definitions
    public class SplitWorkbookResponse : Aspose.Cloud.Common.BaseResponse
    {
        public SplitWorkbook Result { get; set; }
    }
    public class SplitWorkbook
