ExcelR.DotNetCore

Simple dotnet core library contains to create/read xlsx/csv files in an easy way.

Why ExcelR

With the help of ExcelR you can

• Read or write file from/to disk or stream
• Write you list of objects to file
• Read data from file to your model
• Control the color/font of column write to the xlsx file
• Set diffrent heading style
• Can read custom property name with help of excelprop attribute

Examples:-

• Lets we have test class and some sample data as follow

    public class TestModel
   {
       [ExcelRProp(Name = "First Name")]
       public string FirstName { get; set; }
  
  
       [ExcelRProp(ColTextColor = "Red", Name = "Last Name")]
       public string LastName { get; set; }
  
       [ExcelRProp(SkipExport = true)]
       public bool IsMale { get; set; }
  
       [ExcelRProp(HeadTextColor = "Blue" ,Name = "Date Of Birth")]
       public DateTime? Dob { get; set; }
  
   }
   var sampleData =   var list = new List<TestModel>
           {
               new TestModel {IsMale = true, Dob = DateTime.Now, FirstName = "Braat", LastName = "Lee"},
               new TestModel {IsMale = true,  FirstName = "Flintop"},
               new TestModel {IsMale = true, Dob = DateTime.Now.AddDays(15), FirstName = "Michel"},
               new TestModel {IsMale = true, Dob = DateTime.Now, FirstName = "Michel", LastName = "John"},
               new TestModel {IsMale = false, FirstName = "john", LastName = "Cena"}
           };
  

Write and save data to xlsx file

Method1:-

sampleData.ToExcel().Save(filePath);

Method2:-

• Get worksheet and write data to sheet as follow

        var sheet = ExcelExporter.GetWorkSheet();//you can pass custom sheet 
        name 
       //File data in the sheet
        sheet.Write(dataToWrite);
  

• Save sheet to stream or disk

   var stream = sheet.ToStream();
   sheet.Save(filePath);
  

Write and save data to csv file

sampleData.ToCsv(filePath);

Read data from xlsx file or stream

• Get worksheet from file or stream

  var workSheet=ExcelImporter.GetWorkSheet(filePath)
                    Or
   var workSheet=ExcelImporter.GetWorkSheet(stream)
  

• Read data from sheet

  var data= ExcelImporter.Read<TestModel>(sheet);
  

Read data from csv file

 var data = CsvHelper.ReadFromFile<TestModel>(sourceFilePath);

Manually creating xlsx from complex models

     var sheet = ExcelExporter.GetWorkSheet();//you can pass custom sheet name 
      var rowNo=0;
      //create header row
      var headerRow = sheet.CreateRow(rowNo++,Style.H1);
      //Set header values
      headerRow.SetValue(0,"String property")
      //Create data rows and fill data
      foreach(var item in sampleData){
      var dataRow = sheet.CreateRow(rowNo++,Style.H1);
      dataRow.SetValue(0,item.StringProp);
      }
      
      //Save to  file
      sheet.Woorkbook.Save(filePath);
      //Output to stream
       sheet.Woorkbook.ToStream();
