So, I have this method which exports some data into an Excel file:

` public void exportToExcel(string filePath, string sheetName)
{
Microsoft.Office.Interop.Excel.Application excelApplication = new Microsoft.Office.Interop.Excel.Application();
Workbook workBook = excelApplication.Workbooks.Open(filePath, ReadOnly : false);
Worksheet workSheet = (Worksheet)workBook.Worksheets[sheetName];

        int x = 1;

        foreach (string plotName in plotNames)
        {
            x += 2;

            foreach (string property in plotProperties[plotName])
            {
                x += 1;

                foreach (Area area in AreasOrganizer[plotName][property])
                {
                    try
                    {
                        Range cellRangeString = workSheet.Range[$"A{x}", $"B{x}"];
                        Range cellRangeDouble = workSheet.Range[$"C{x}", $"X{x}"];

                        /* configuring data to be written */

                        string[] areaStringData = new[] { areaNumber, areaName };
                        double[] areasDoubleData = new[] { areaArea, areaSubjected, ACGA, ACOR, ACLE, ACLO, ACHE, ACRO, ACSP, ACST, ACZO, ACCO, C1C2, areaCommonPercent, areaCommonArea, areaTotalArea, areaPermitPercent, areaRLPPercentage, areaRLP };

                        cellRangeString.set_Value(XlRangeValueDataType.xlRangeValueDefault, areaStringData);
                        cellRangeDouble.set_Value(XlRangeValueDataType.xlRangeValueDefault, areasDoubleData);                            
                    }
                    catch
                    {
                        Range cellRangeString = workSheet.Range[$"A{x}", $"B{x}"];
                        string[] cellsStrings = new[] { "X", "Y" };
                        cellRangeString.set_Value(XlRangeValueDataType.xlRangeValueDefault, cellsStrings);
                    }

                    x += 1;
                }
            }
        }

        workBook.Save();
        workBook.Close();
    }`

The method works just fine, but once I try to open the file manually afterwards, it asks to be opened in Safe Mode:

It’s not a big deal, but it’s just a bit annoying, so if anyone knows how to fix this, that would be awesome! It’s the first time I’m using Microsoft.Office.Interop.Excel. And I don’t think the problem comes from internal Excel configuration, as it only happens when I edit the file from my plug in and never when doing it manually 🙂 thanks in advance!
