Saving Excel workbook even the tool collapsed or thrown an error in C#

I've code like below;

            if (CreateExcelFile(output_file))
            {
                var workbook = new ClosedXML.Excel.XLWorkbook(output_file);

// Additional to-do will list in here

                GenTplParams(workbook); //This writes something in excel

                workbook.SaveAs(output_file);
            }
        }

Select allOpen in new window

GenTplParams() is writing some values on that excel file from 3rd party tool and sometimes it can crash or thrown an error while processing and when i'm getting at the end a blank excel file.

But i'd like to get the file with already written values until the crash/error occurs also it'll give me an advantage to find out which value gives an error. I can easily read the excel file and check the last value and figure out the next value has a problem.

P.S. values are getting from 3rd party softwares COM objects.

Any help makes me glad. Thank you.
