DataJuggler.ExcelerateWinApp

ExcelerateWinApp is a WinForms app designed to make it easy to load and save Excel objects that were created using

Blazor Excelerate

https://excelerate.datajuggler.com
Code Generate C# Classes From Excel Header Rows

Instructions to run this project:

To Install Via Nuget and DOT NET CLI, navigate to the folder you wish to create your project in

cd c:\Projects\ExcelerateWinApp
dotnet new install DataJuggler.ExcelerateWinApp
dotnet new DataJuggler.ExcelerateWinApp

or

Clone this project from GitHub https://github.com/DataJuggler/ExcelerateWinApp

Setup Instructions

1. Create one or more classes from Excel Header Rows at
   
   

Blazor Excelerate
https://excelerate.datajuggler.com

Download the file MemberData.xlsx from the above site to see an example. Use ExcelerateWinApp.Objects for the namespace or rename this project to your liking

2. Copy the classes created into the Objects folder of ExcelerateWinApp

3. Load Excel Worksheet(s) - Example is included in the UpdateButton_Click event

   // load your object(s)
   string workbookPath = FileSelector.Text;
   
   // Example WorksheetInfo objects           
   WorksheetInfo info = new WorksheetInfo();
   info.LoadColumnOptions = LoadColumnOptionsEnum.LoadAllColumnsExceptExcluded;
   info.Path = workbookPath;	
   
   // Set your SheetName
   info.SheetName = "Address";
   
   // Example WorksheetInfo objects           
   WorksheetInfo info2 = new WorksheetInfo();
   info2.LoadColumnOptions = LoadColumnOptionsEnum.LoadAllColumnsExceptExcluded;
   info2.Path = workbookPath;
   
   // Set the SheetName for info2
   info2.SheetName = 'States";
   
   // Example load Worksheets
   Worksheet addressWorksheet = ExcelDataLoader.LoadWorksheet(workbookPath, info);
   Worksheet statesWorksheet = ExcelDataLoader.LoadWorksheet(workbookPath, info2);
   

4. Load your list of objects

    // Examples loading the Address and States sheet from MemberData.xlsx
    List<Address> addresses = Address.Load(addressWorksheet);
    List<States> states = States.Load(statesWorksheet);
   

5. Perform updates on your List of objects

   For this example, I inserted a column StateName into the Address sheet in Excel and added a few state names manually. You must add a few entries so the data type can be attempted to be determined. Then I code generated Address and States classes using Blazor Excelerate
   https://excelerate.datajuggler.com

   This method set the Address.StateName for each row by looking up the State Name by StateId

   /// <summary>
   /// Lookup the StateName for each Address object by StateId
   /// </summary>
   public void FixStateNames(ref List<Address> addresses, List<States> states)
   {
       // verify both lists exists and have at least one item
       if (ListHelper.HasOneOrMoreItems(addresses, states))
       {
          // Iterate the collection of Address objects
          foreach (Address address in addresses)
          {
              // get a local copy
              int stateId = address.StateId;
   
              // set the stateName
              address.StateName = states.Where(x => x.Id == stateId).FirstOrDefault().Name;
   
              // Increment the value for Graph
              Graph.Value++;
   
              // update the UI every 100
              if (Graph.Value % 100 == 0)
              {
                  Refresh();
                  Application.DoEvents();
               }
          }
       }
    }
   

6. Save your worksheet back to Excel

   // resetup the graph                    
   Graph.Maximum = addresses.Count;
   Graph.Value = 0;
   
   // change the text
   StatusLabel.Text = "Saving Addresses please wait...";
   
   // you must convert the list objects to List<IExcelerateObject> before it can be saved
   List<IExcelerateObject> excelerateObjectList = addresses.Cast<IExcelerateObject>().ToList();
   
   // Now save the worksheet
   SaveWorksheetResponse response = ExcelHelper.SaveWorksheet(excelerateObjectList, addressWorksheet, info, SaveWorksheetCallback, 500);
