/ Published in: C#
Save to your folder(s)
This technical tip shows how developers can split worksheets of an Excel 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.
