Edit watermarks in Excel documents using .NET

GroupDocs.Watermark for .NET empowers .NET developers to effortlessly edit watermarks within various Excel documents. Here’s a simplified guide how to use our API in your application:

Begin by passing your Excel file as a parameter to the Watermarker class constructor. You can provide the file either as a byte stream, a file stream, or a local disk path.
Next, locate the specific watermarks that require editing. Utilize the SearchCriteria to identify watermarks with the corresponding properties previously added to the document.
Following the search, you’ll obtain a list of relevant watermarks. You can then customize their properties, such as size, page alignment, text, color, image content, and more. This grants you extensive control over your data.
Once you’ve completed editing the watermarks, save the updated document. You can utilize a local file path or a stream to store the final result.

Copy

// Edit EXCEL text watermark

// Make Watermarker providing EXCEL file
using (Watermarker watermarker = new Watermarker("input.xslx"))
{
    // Construct the TextSearchCriteria and get text watermarks
    TextSearchCriteria searchCriteria = new TextSearchCriteria("test", false);
    PossibleWatermarkCollection watermarks = watermarker.Search(searchCriteria);

    foreach (PossibleWatermark watermark in watermarks)
    {
         // Edit text watermark
         watermark.FormattedTextFragments.Clear();
         watermark.FormattedTextFragments.Add("passed", 
            new Font("Calibri", 19, FontStyle.Bold), Color.Red, Color.Aqua);
    }

    // Save the document
    watermarker.Save("output.xslx");
}
