这篇文章主要介绍了C# 将CSV转为Excel,转换之后可执行更多关于数据编辑、格式设置等操作，代码简单易懂，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友参考下吧
CSV(Comma Separated Values)文件是一种纯文本文件，包含用逗号分隔的数据，常用于将数据从一个应用程序导入或导出到另一个应用程序。通过将CSV文件转为EXCEL，可执行更多关于数据编辑、格式设置等操作。下面，将通过C#及VB.NET代码展示如何来实现转换。
一、程序环境
可通过以下途径来安装Excel库：
1. 通过NuGet安装Spire.XLS；
2. 官方下载包，解压安装到本地指定路径。在Visual Studio中打开“解决方案资源管理器”，将本地安装路径下Bin文件夹下的dll添加引用至程序。
二、将CSV转为Excel
C#
using Spire.Xls;
namespace CSVtoExcel_XLS
{
class Program
{
static void Main(string[] args)
{
//加载CSV文件
Workbook workbook = new Workbook();
workbook.LoadFromFile("test.csv", ",", 1, 1);
//获取第一个工作表
Worksheet sheet = workbook.Worksheets[0];
//访问工作表中使用的范围
CellRange usedRange = sheet.AllocatedRange;
//当将范围内的数字保存为文本时，忽略错误
usedRange.IgnoreErrorOptions = IgnoreErrorType.NumberAsText;
//自适应行高、列宽
usedRange.AutoFitColumns();
usedRange.AutoFitRows();
//保存文档
workbook.SaveToFile("result.xlsx", ExcelVersion.Version2013);
System.Diagnostics.Process.Start("result.xlsx");
}
}
}VB.NET
Imports Spire.Xls
Namespace CSVtoExcel_XLS
Class Program
Private Shared Sub Main(args As String())
'加载CSV文件
Dim workbook As New Workbook()
workbook.LoadFromFile("test.csv", ",", 1, 1)
'获取第一个工作表
Dim sheet As Worksheet = workbook.Worksheets(0)
'访问工作表中使用的范围
Dim usedRange As CellRange = sheet.AllocatedRange
'当将范围内的数字保存为文本时，忽略错误
usedRange.IgnoreErrorOptions = IgnoreErrorType.NumberAsText
'自适应行高、列宽
usedRange.AutoFitColumns()
usedRange.AutoFitRows()
'保存文档
workbook.SaveToFile("result.xlsx", ExcelVersion.Version2013)
System.Diagnostics.Process.Start("result.xlsx")
End Sub
End Class
End Namespace
补充知识：C# .csv文件转为Excel格式；Excel格式转换为.csv，代码如下所示：
using System;
using System.Diagnostics;
using System.IO;
using System.Reflection;
using System.Windows.Forms;
using Excel=Microsoft.Office.Interop.Excel;
namespace WinFromAPP
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
/// <summary>
/// 将Csv文件转换为XLS文件
/// </summary>
/// <param name="FilePath">文件全路路径</param>
/// <returns>返回转换后的Xls文件名</returns>
public static string CSVSaveasXLS(string FilePath)
QuertExcel();
string _NewFilePath = "";
Excel.Application excelApplication;
Excel.Workbooks excelWorkBooks = null;
Excel.Workbook excelWorkBook = null;
Excel.Worksheet excelWorkSheet = null;
try
{
excelApplication = new Excel.ApplicationClass();
excelWorkBooks = excelApplication.Workbooks;
excelWorkBook = ((Excel.Workbook)excelWorkBooks.Open(FilePath, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value));
excelWorkSheet = (Excel.Worksheet)excelWorkBook.Worksheets[1];
excelApplication.Visible = false;
excelApplication.DisplayAlerts = false;
_NewFilePath = FilePath.Replace(".csv", ".xls");
excelWorkBook.SaveAs(_NewFilePath, Excel.XlFileFormat.xlAddIn, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
excelWorkBook.Close();
QuertExcel();
// ExcelFormatHelper.DeleteFile(FilePath);
//可以不用杀掉进程QuertExcel();
GC.Collect(System.GC.GetGeneration(excelWorkSheet));
GC.Collect(System.GC.GetGeneration(excelWorkBook));
GC.Collect(System.GC.GetGeneration(excelApplication));
}
catch (Exception exc)
throw new Exception(exc.Message);
finally
GC.Collect();
return _NewFilePath;
/// 将xls文件转换为csv文件
/// <returns>返回转换后的csv文件名</returns>
public static string XLSSavesaCSV(string FilePath)
_NewFilePath = FilePath.Replace(".xls", ".csv");
// excelWorkSheet._SaveAs(FilePath, Excel.XlFileFormat.xlCSVWindows, Missing.Value, Missing.Value, Missing.Value,Missing.Value,Missing.Value, Missing.Value, Missing.Value);
excelWorkBook.SaveAs(_NewFilePath, Excel.XlFileFormat.xlCSV, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
//ExcelFormatHelper.DeleteFile(FilePath);
/// 删除一个指定的文件
/// <param name="FilePath">文件路径</param>
/// <returns></returns>
public static bool DeleteFile(string FilePath)
bool IsFind = File.Exists(FilePath);
if (IsFind)
{
File.Delete(FilePath);
}
else
throw new IOException("指定的文件不存在");
return true;
/// 执行过程中可能会打开多个EXCEL文件 所以杀掉
private static void QuertExcel()
Process[] excels = Process.GetProcessesByName("EXCEL");
foreach (var item in excels)
item.Kill();
private void btnConvert_Click(object sender, EventArgs e)
//CSVSaveasXLS(textBox1.Text);
XLSSavesaCSV(textBox1.Text);
}
