To create new records, use INSERT statements.

INSERT Syntax

The INSERT statement specifies the columns to be inserted and the new column values. You can specify the column values in a comma-separated list in the VALUES clause, as shown in the following example:

INSERT INTO <table_name> 
( <column_reference> [ , ... ] )
VALUES 
( { <expression> | NULL } [ , ... ] ) 
  

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the rows affected, as shown in the following example:

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;";
using (ExcelOnlineConnection connection = new ExcelOnlineConnection(connectionString)) {
  int rowsAffected;
  ExcelOnlineCommand cmd = new ExcelOnlineCommand("INSERT INTO Test_xlsx_Sheet1 (Column1) VALUES ('John')", connection);
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;"
Using connection As New ExcelOnlineConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ExcelOnlineCommand("INSERT INTO Test_xlsx_Sheet1 (Column1) VALUES ('John')", connection)
  rowsAffected = cmd.ExecuteNonQuery()
End Using
