Exception From Hresult 0x800a03ec Opening Excel File

running Excel add-in with following code: Excel.Range rng = ActiveSheet.Cells[x, y] as Excel.Range; string before = rng.Value2; string cleanV = System.Text.RegularExpressions.Regex.Replace(before, @"\s+", ""); rng.set_Value(cleanV); When error happens X and Y are set to 1, thus Excel range is not violated. I searched extensively and tried a number of ways of setting the cell value (eg. Cells[x,y], range.set_Value()) but am at loss why this error happens and how to avoid it. Any help is greatly appreciated. Below are exception details: System.Runtime.InteropServices.COMException was unhandled by user code HResult=-2146827284 Message=Exception from HRESULT: 0x800A03EC Source="" ErrorCode=-2146827284 StackTrace: at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData) at Microsoft.Office.Interop.Excel.Range.set_Value(Object RangeValueDataType, Object value) at ImportValidation.ThisAddIn.removeAnySpaces(Int32 x, Int32 y) in c:\Users\dshevelev\Documents\Visual Studio 2012\Projects\ImportValidation\ImportValidation\ThisAddIn.cs:line 354 at ImportValidation.ThisAddIn.ReadHeaders(Hashtable columnAddress) in c:\Users\dshevelev\Documents\Visual Studio 2012\Projects\ImportValidation\ImportValidation\ThisAddIn.cs:line 123 at ImportValidation.ThisAddIn.mapColumns() in c:\Users\dshevelev\Documents\Visual Studio 2012\Projects\ImportValidation\ImportValidation\ThisAddIn.cs:line 493 at ImportValidation.Ribbon1.button6_Click(Object sender, RibbonControlEventArgs e) in c:\Users\dshevelev\Documents\Visual Studio 2012\Projects\Import

Also you can try to open it normally and see what happens. But if you just want to know, whether the file is corrupt or not, this exception gives you the information: yes, the file is corrupt. share|improve this answer edited Mar 16 '15 at 12:26 answered Mar 16 '15 at 7:45 Vojtěch Dohnal 4,01411338 what is this books how can i merge this with my code –Bheeshamteche Mar 16 '15 at 11:56 @Bheeshamteche books is a local variable that you have declared in your code....
