Remove Image Background in Excel using C# REST API

Master the process of removing an image background in Excel using a C# REST API quickly and efficiently. In this tutorial you’ll leverage the .NET‑based Aspose.Cells Cloud SDK to remove picture backgrounds in Excel via the REST interface, and you’ll also see how to clear the background of a single worksheet.

Prerequisite

Steps to Remove Picture Background in Excel using C# REST Interface

  1. Set up the CellsApi object using your client ID, client secret, and the Aspose Cloud base URL
  2. Open the target Excel file and create an UploadFileRequest to upload it to Aspose Cloud storage
  3. Send the upload request to the cloud using the UploadFile() method of the CellsApi class
  4. Construct a DeleteWorkbookBackgroundRequest object with the file name and default storage/folder settings
  5. Call DeleteWorkbookBackground() with the prepared request to remove the workbook’s background
  6. Use DownloadFileRequest and DownloadFile() to retrieve the modified Excel file from the cloud
  7. Write the downloaded stream to a new local file using FileStream

These steps summarize the process of how to remove image background in Excel using C# RESTful Service. This process connects to Aspose.Cells Cloud using API credentials, uploads an Excel file, and removes its background using a dedicated API request. After the background is removed, the updated file is downloaded and saved locally.

Code to Remove Image Background in Excel using C# REST API

The example code walks you through removing a photo background from an entire Excel workbook with the C# .NET API. If you need to clear the background on just one worksheet—or on a specific set of sheets—simply call DeleteWorksheetBackground() and pass the desired sheet name(s) to delete that sheet’s background image.
