Unmask Hidden XLSX Spreadsheets Watermarks Instantly

Quickly unmask and manage hidden watermarks with GroupDocs.Watermark for .NET.

Efficiently Find Xlsx Watermarks with .NET

GroupDocs.Watermark offers a robust solution for programmatically finding watermarks within various business document formats. Integrate our package into your .NET applications to empower them with watermark finding capabilities.

To exploit the functionalities of our library, instantiate the Watermarker class and provide the Xlsx file path, file stream, or byte stream as input. This action loads the document for watermark analysis.
For targeted watermark identification, leverage the SearchCriteria object. Specify an image for locating similar image watermarks. Alternatively, for textual watermarks, define the text content, font properties, color attributes, and other pertinent parameters to refine the search criteria.
Employ the Search method of the Watermarker object to initiate the watermark detection process within the loaded document. This function returns a collection of objects representing potential watermarks, enabling further processing.
The retrieved collection of watermark objects grants you precise control. You can programmatically remove unwanted watermarks or dynamically modify their properties, such as adjusting their size or text content, to suit your specific requirements.
