Integrated Storage API

Since version 19.9, the SDK includes support of storage operations for better user experience and unification, so now there's no need to use 2 different SDKs!

It gives you an ability to:

  • Upload, download, copy, move and delete files, including versions handling (if you are using Cloud storage that supports this feature - true by default).
  • Create, copy, move and delete folders.
  • Copy and move files and folders across separate storages in scope of a single operation.
  • Check if certain file, folder or storage exists.

Get Started with Aspose.Cells Cloud SDK for .NET

You do not need to install anything to get started with Aspose.Cells Cloud SDK for .NET. Just create an account at Aspose for Cloud and get your application information.

Next, execute Install-Package Aspose.Cells-Cloud from the Package Manager Console in Visual Studio to fetch & reference Aspose.Cells Cloud SDK assembly in your project. If you already have Aspose.Cells Cloud SDK for .NET and want to upgrade it, please execute Update-Package Aspose.Cells-Cloud to get the latest version.

Add a Worksheet to an Excel File in the Cloud

The following code snippet demonstrates how to add a new worksheet to a Microsoft Excel document using C# code:

CellsApi cellsApi =CellsApi(clientId, clientSecret);
string localName = "Book1.xlsx";
string remoteName = "Book1.xlsx";

this.UploadFile( localName, remoteFolder + "/" + remoteName, "");

var request = new PutAddNewWorksheetRequest(
    name: remoteName,
    sheetName: "Sheet1",
    position: 0,
    sheettype: "VB",
    folder: remoteFolder,
    storageName: ""

Convert Excel Files via C# Code

The following code example elaborates Aspose.Cells REST API to convert an Excel file to another format in the cloud:

CellsApi cellsApi =CellsApi(clientId, clientSecret);
// Upload source file to aspose cloud storage
string localName = "Book1.xlsx";
string remoteName = "Book1.xlsx";

this.UploadFile( localName, remoteFolder + "/" + remoteName, "");

var saveOptions = new PdfSaveOptions()
    SaveFormat = format
var request = new PostWorkbookSaveAsRequest(
    name: remoteName,
    newfilename: newfilename,
    saveOptions: saveOptions,
    folder: remoteFolder
