Remove Watermarks from Excel Documents Using .NET

GroupDocs.Watermark simplifies the task of removing watermarks from business documents. Empower your .NET application by integrating our library and follow these simple steps:

  1. Begin by instantiating the main class, Watermarker, with the Excel document. Our API supports processing documents provided as either a stream or a local path.
  2. Utilize SearchCriteria to narrow down the set of watermarks to be processed. You can use various parameters such as images, text, or formatting features. The more specific the search parameters you provide, the more precise the results you obtain.
  3. Process the list of document watermarks obtained as a search result and remove them from the document.
  4. After removing the watermarks, save the resulting document as a local file or a byte stream.
