I have a large excel worksheet that I want to add to my database.

Can I generate an SQL insert script from this excel worksheet?

Answer 1

You can use the below C# Method to generate the insert scripts using Excel sheet just you need import OfficeOpenXml Package from NuGet Package Manager before executing the method.

public string GenerateSQLInsertScripts() {

        var outputQuery = new StringBuilder();
        var tableName = "Your Table Name";
        if (file != null)
        {
            var filePath = @"D:\FileName.xsls";

            using (OfficeOpenXml.ExcelPackage xlPackage = new OfficeOpenXml.ExcelPackage(new FileInfo(filePath)))
            {
                var myWorksheet = xlPackage.Workbook.Worksheets.First(); //select the first sheet here
                var totalRows = myWorksheet.Dimension.End.Row;
                var totalColumns = myWorksheet.Dimension.End.Column;

                var columns = new StringBuilder(); //this is your columns

                var columnRows = myWorksheet.Cells[1, 1, 1, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());

                columns.Append("INSERT INTO["+ tableName +"] (");
                foreach (var colrow in columnRows)
                {
                    columns.Append("[");
                    columns.Append(colrow);
                    columns.Append("]");
                    columns.Append(",");
                }
                columns.Length--;
                columns.Append(") VALUES (");
                for (int rowNum = 2; rowNum <= totalRows; rowNum++) //selet starting row here
                {
                    var dataRows = myWorksheet.Cells[rowNum, 1, rowNum, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());

                    var finalQuery = new StringBuilder(); 
                    finalQuery.Append(columns);

                    foreach (var dataRow in dataRows)
                    {
                        finalQuery.Append("'");
                        finalQuery.Append(dataRow);
                        finalQuery.Append("'");
                        finalQuery.Append(",");
                    }
                    finalQuery.Length--;

                    finalQuery.Append(");");

                    outputQuery.Append(finalQuery);

                  }

            }
        }

return outputQuery.ToString();}
