Effortlessly Delete Watermarks from Xlsx by Node.js via Java

GroupDocs.Watermark streamlines the process of removing watermarks from business documents. Elevate your Node.js via Java application by seamlessly integrating our library and following these straightforward steps:

Initiate the process by instantiating the core class, Watermarker, with the Xlsx document. Our versatile API seamlessly processes documents, whether provided as a stream or a local path.
Leverage SearchCriteria to precisely pinpoint the watermarks to be addressed. Utilize various parameters such as images, text, or formatting features to refine your search. The more detailed your criteria, the more accurate your results.
Execute the removal process on the list of document watermarks retrieved through your search. Effortlessly delete them from the document.
Upon successfully deleting the watermarks, securely save the resulting document as a local file or a byte stream, preserving its integrity.
