Upload the Excel File

Reproduce Steps

I open a file with formulas in it. I change the value of 2 cells and after I call XSSFFormulaEvaluator.EvaluateAllFormulaCells(newWorkbook);

after that I open the file with the MS Excel Interop (here is my code)

"Excel.Application excelApp = new();

Excel.Workbook wb = excelApp.Workbooks.Open(fileName,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);

Excel.Worksheet ws = (Excel.Worksheet)wb.Worksheets[1];"

And on the last line the application crash with error code : 0x800A03EC

Issue Description

If I open the file in Excel, Excel says the file is corrupt and he fix it the the message : "remove /xl/calcChain.xml"

I rollback to 2.6.2 and the Excel files are not corrupt anymore.

thank you.

It seems to be smth wrong with shared formulas...
Can you please also provide your code to modificate the original file?

Hi, here the code. I clean up it because there is a connection to DB

string filename = "" //the filename goes here.

XSSFWorkbook newWorkbook = new();
XSSFSheet excelSheet = new();

initializeWorkbook(ref filename, ref newWorkbook, ref excelSheet);
int rowIndex = 1;

IRow row = excelSheet.CreateRow(rowIndex);

row.CreateCell(0).SetCellValue(12002219);
row.CreateCell(1).SetCellValue((double)2.2);

XSSFFormulaEvaluator.EvaluateAllFormulaCells(newWorkbook);

using FileStream fs = new(filename, FileMode.Create, FileAccess.Write);
newWorkbook.Write(fs);
fs.Close();

PrintMyExcelFile(filename);

//this code initialize the document
private void initializeWorkbook(ref string filename, ref XSSFWorkbook newWorkbook, ref XSSFSheet excelSheet)
{
newWorkbook = new();

 using (FileStream filestream = new(filename, FileMode.Open, FileAccess.Read))
 {
     newWorkbook = new XSSFWorkbook(filestream);
     filestream.Close();
 }

 int rowIndex = 0;

 excelSheet = (XSSFSheet)newWorkbook.GetSheet("A PRODUIRE");

 if (excelSheet != null)
 {
     while (excelSheet.GetRow(rowIndex) != null)
     {
         excelSheet.GetRow(rowIndex).GetCell(0)?.SetCellValue(0);
         excelSheet.GetRow(rowIndex).GetCell(1)?.SetCellValue(0);
         rowIndex++;
     }
 }
 else
 {
     excelSheet = (XSSFSheet)newWorkbook.CreateSheet("A PRODUIRE");
 }
 

 IRow row = excelSheet.CreateRow(0);

 row.CreateCell(0).SetCellValue("ItemId");
 row.CreateCell(1).SetCellValue("Qté à produire");
 row.CreateCell(2).SetCellValue(SelectedDate.Date);

}

//this code is for printing but crash at the line : Excel.Worksheet ws = (Excel.Worksheet)wb.Worksheets[1];
private void PrintMyExcelFile(string fileName)
{
Excel.Application excelApp = new();

 Excel.Workbook wb = excelApp.Workbooks.Open(fileName,
     Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
     Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
     Type.Missing, Type.Missing, Type.Missing, Type.Missing);

 Excel.Worksheet ws = (Excel.Worksheet)wb.Worksheets[1];
 for (int i = 1; i <= wb.Worksheets.Count; i++)
 {
     if (((Excel.Worksheet)wb.Worksheets[i]).Name == "MAIN")
     {
         ws = (Excel.Worksheet)wb.Worksheets[i];
         ws.PrintOut(Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
         break;
     }
 }

 // Cleanup:
 GC.Collect();
 GC.WaitForPendingFinalizers();

 Marshal.FinalReleaseComObject(ws);

 wb.Close(false, Type.Missing, Type.Missing);
 Marshal.FinalReleaseComObject(wb);

 excelApp.Quit();
 Marshal.FinalReleaseComObject(excelApp);

}

Hope you will have the possibility to reproduce the error and fix it.
