I need to programmatically insert a row into an Excel Spreadsheet multiple times. I need to actually insert a new row and not insert data, that is, I need to actually shift all other rows down by one.
I am currently using OleDB to insert the data itself like so:
//Note I have missed some code out for simplicities sake, this all works fine however
OleDbConnection oledbConn = null;
OleDbCommand cmd = null;
OleDbConnection = new OleDbConnection(connString);
OleDbConnection.Open();
string connString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0; \"", TargetFile);
sting InsertCommand = string.Format("INSERT INTO [{0}${1}:{1}] Values({2})", WorksheetName, Coord, valuestring);
cmd = new OleDbCommand(InsertCommand, oledbConn);
cmd.ExecuteNonQuery();
//close etc
I want to be able to insert a row in a similar fashion. Is this possible?
At a glance, you need to specify read write, the default is read only. Perhaps: "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:\\Docs\\Test.xls;" & _ "Mode=ReadWrite;Extended Properties=""Excel 8.0;HDR=No"""
At a second glance and re comments, I think Interop might be the best bet.
ipavlic is right, you will be better off using an external third-party library for this. There are several available. OfficeWriter is one example:
Once you open a workbook with OfficeWriter, you can use this method on the Worksheet class to insert rows. It mimics Excel's behavior, including updating/stretching formulas and other updates:
public void InsertRows(int rowNumber, int rowCount)
