Read and write Excel XLS, XLSX, CSV files |
Bytescout Spreadsheet SDK is a clean and simple API to read and write Excel files.
Almost in every business application we need to have the ability to read and write Excel files. Using Bytescout Spreadsheet SDK is a simple way of reading and writing Excel files using C# (CSharp).
Sample source code – write data to Excel file in C#:
using System; using System.Collections.Generic; using System.Text; using Bytescout.Spreadsheet; using System.IO; using System.Diagnostics; <span data-scayt_word="namespace" data-scaytid="5">namespace</span> <span data-scayt_word="HelloWorld" data-scaytid="6">HelloWorld</span> { class Program { static void Main(string[] <span data-scayt_word="args" data-scaytid="8">args</span>) { // Create new Spreadsheet Spreadsheet document = new Spreadsheet(); // Add new worksheet Worksheet worksheet = document.Workbook.Worksheets.Add("<span data-scayt_word="HelloWorld" data-scaytid="7">HelloWorld</span>"); // Set cell value worksheet.Cell(0, 0).Value = "Hello, World!"; // delete output file if exists already if (File.Exists("Output.xls")){ File.Delete("Output.xls"); } // Save document document.SaveAs("Output.xls"); // Close Spreadsheet document.Close(); // open generated <span data-scayt_word="XLS" data-scaytid="4">XLS</span> document in default program Process.Start("Output.xls"); } } }
Sample source code – read data from Excel file in C#:
using System; using System.Collections.Generic; using System.Text; using Bytescout.Spreadsheet; <span data-scayt_word="namespace" data-scaytid="10">namespace</span> <span data-scayt_word="HelloWorld" data-scaytid="11">HelloWorld</span> { class Program { static void Main(string[] <span data-scayt_word="args" data-scaytid="12">args</span>) { // Create new Spreadsheet Spreadsheet document = new Spreadsheet(); document.LoadFromFile("Hello_world.xlsx"); // Get worksheet Worksheet worksheet = document.Workbook.Worksheets.ByName("<span data-scayt_word="Sheet1" data-scaytid="16">Sheet1</span>"); // Read cell value Console.WriteLine("Cell (0,0) value: {0}", worksheet.Cell(0, 0).ValueAsString); // Write message Console.Write("Press any key to continue..."); // Wait user input Console.ReadKey(); } } }
