To add AWS ToolKit for visual studio follow this link Using the AWS Lambda Templates in the AWS Toolkit for Visual Studio

Installing AWS ToolKit into Visual studio enables you to create AWS Lambda Function Project. You Can Learn how to Create AWS Lambda Function Project using Visual studio using This Link

Working AWS Lambda Function Code Example

After Creating New AWS Lambda Function project you try this code snippet

    namespace AWSLambdaIronXL
    {
        public class Function
        {

        /// <summary>
        /// A simple function that takes a string and does a ToUpper
        /// </summary>
        /// <param name="input"></param>
        /// <param name="context"></param>
        /// <returns></returns>
        public string FunctionHandler(string input, ILambdaContext context)
        {
            WorkBook workBook = WorkBook.Create(ExcelFileFormat.XLS);

            var newSheet = workBook.CreateWorkSheet("new_sheet");
            string ColumnsNames = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
            foreach (char col in ColumnsNames)
            {
                for (int row = 1; row <= 50; row++)
                {
                    var cellName = $"{col}{row}";
                    newSheet[cellName].Value = $"Cell : {cellName}";
                }
            }

            return Convert.ToBase64String( workBook.ToByteArray());
        }
        }
    }
