Additional code

public static void ExportHtml(string inputPath, string htmlOutputPath)
{
    Workbook wbc = null;
    using (var ms = new FileStream(inputPath, FileMode.Open))
    {
        wbc = new Workbook(ms, new LoadOptions(LoadFormat.Xlsx));
    }

    var range = wbc.GetRangeByNamedRange("To_Publish");
    var worksheet = range.Worksheet;
    worksheet.PageSetup.PrintArea = range.Address;
    wbc.Worksheets.ActiveSheetIndex = worksheet.Index;
    using var html = new MemoryStream();
    wbc.Save(html, _htmlSaveOptions);
    File.WriteAllBytes(htmlOutputPath, html.ToArray());

@aleksandr.l,

Thanks for the template Excel file and code snippet.

We require thorough evaluation of your issue in your mentioned environment. By the way, if you render to HTML (Web page) via MS Excel, does it also break the layout on MacBook in Safari? In any case, we have opened the following new ticket(s) in our internal issue tracking system and will deliver their fixes according to the terms mentioned in Free Support Policies.

We tried to do as you said, but we took worse layout.

HTML page works fine on windows in Google Chrome and on Macbook 16’ in Google Chrome, but layout “floats” on Macbook 16’ in Safari. I think there’s a problem with spaces.

@aleksandr.l,

Thanks for sharing further details with screenshot.

It means, the issue you’re experiencing with the layout breaking or becoming distorted on a MacBook in Safari may not be directly related to Aspose.Cells, as the component adheres to Microsoft Excel standards and specifications when rendering to the HTML file format. It’s possible that the issue lies with the Safari browser. We’ll thoroughly evaluate your issue and provide you with an update soon.
