Aspose.Cells for .NET 7.7.2 hangs when trying to open Excel file

Please see attached file and coding used. Program stops when instantiating new Workbook(oldName).

static bool SaveExcelFile(string oldName)


bool saveStatus;

var newName = oldName.Replace(“Inbox”, “Batch”);

var newFileInfo = new FileInfo(newName);

newName = newName.Replace(newFileInfo.Extension, “_pgnum.tif”);



var imgOptions = new Aspose.Cells.Rendering.ImageOrPrintOptions


ImageFormat = ImageFormat.Tiff,

HorizontalResolution = 200,

VerticalResolution = 200,

TiffCompression = Aspose.Cells.Rendering.TiffCompression.CompressionCCITT4,

OnePagePerSheet = true


var saveExcelWorkbook = new Aspose.Cells.Workbook(oldName);

var saveWorksheetColl = saveExcelWorkbook.Worksheets;

var wsCount = saveWorksheetColl.Count;

for (int ws = 0; ws

var sheet = saveWorksheetColl[ws];

if (sheet.Cells.Count == 0 || sheet.CodeName == “Look ups”

|| sheet.CodeName == “Instructions for use”

|| sheet.CodeName == “Internal Instructions”

|| sheet.CodeName == “Autouploader” || !sheet.IsVisible)




sheet.ViewType = Aspose.Cells.ViewType.NormalView;

var wsRender = new Aspose.Cells.Rendering.SheetRender(sheet, imgOptions);

var saveName = newName.Replace(“pgnum", "” + ws.ToString(“00”));



saveStatus = true;


catch (Exception exc)


Console.WriteLine(“Exception converting Excel Doc to TIF - {0}”, exc.Message);

Log.Error(oldName, “Exception converting Excel Doc to TIF”, exc.Message);

saveStatus = false;



return saveStatus;
