Excel to HTML uses global styles in .NET


using GroupDocs.Viewer 24.2 to convert the any XLSX to HTML, adds styles for TR and TD.

Those global styles interfere with our web application and it would be great, if they could be removed / renamed.

        using (var viewer = new View.Viewer(documentPath))
            var options = ViewOpts.HtmlViewOptions.ForEmbeddedResources("output_viewer{0}.html");
            //options.SpreadsheetOptions = ViewOpts.SpreadsheetOptions.ForOnePagePerSheet();
            //options.SpreadsheetOptions.RenderGridLines = true;
            //options.SpreadsheetOptions.RenderHeadings = true;

The problem seems to happen in both cases, with and without the commented out code.
