Repro of an issue with Syncfusion XlsIO upgrade.

Fixed.cs

using (var excel = new ExcelEngine())
{
    var workbook = excel.Excel.Workbooks.Open(fileName);
    var sheet = workbook.Worksheets[sheetName];

    var exportWorkbook = excel.Excel.Workbooks.Add(ExcelVersion.Excel2013); // Increases the maximum number of allowed rows.
    var exportSheet = exportWorkbook.Worksheets.Create();
    exportSheet.IsStringsPreserved = true; // Prevents leading zeroes from being dropped.

    sheet.UsedRange.CopyTo(exportSheet.Range["A1"]);
}

FollowUp.cs

// Replacing the CopyTo call with the following block:
foreach (IRange cell in sheet.UsedRange)
    exportSheet.Range[cell.AddressLocal].Value = cell.Value;

// Has 3 issues:
// - Not as quick
// - Drops leading zeroes, for instance zipcode 02360 becomes 2360
// - In .xlsx files, throws an ArgumentOutOfRangeException on the 65537th row. (UInt16.MaxValue + 2??)

SyncfusionSnippet.cs

using (var excel = new ExcelEngine())
{
    // Open the Excel document and retrieve the appropriate work sheet.
    var workbook = excel.Excel.Workbooks.Open(@"C:\Path\To\Some\File.xlsx");
    var sheet = workbook.Worksheets["Sheet1"];

    // Create a new work sheet to export.
    var exportWorkbook = excel.Excel.Workbooks.Add();
    var exportSheet = exportWorkbook.Worksheets.Create();

    // Copy the data to the export work sheet.
    // "A1" is the first cell in the work sheet,
    // the copy will expand into more cells to
    // fit the size of the data source.
    sheet.UsedRange.CopyTo(exportSheet.Range["A1"]);
    // The line above throws an ArgumentOutOfRangeException in v11.3035.0.30, worked in v8.403.0.10.
    
    // ...
