Open and Save

The native data format for Spreadsheet is JSON. You can load and store JSON data with Spreadsheet. In Spreadsheet we have saveAsJSON and loadFromJSON method which is used to save Spreadsheet as JSON and same JSON used to render Spreadsheet.

  • javascript
  • function saveAsJSON() {
        var excelObj = $("#Spreadsheet").data("ejSpreadsheet");
        window.excelData = excelObj.saveAsJSON();
    }
    
    function loadFromJSON() {
        var excelObj = $("#Spreadsheet").data("ejSpreadsheet");
        excelObj.loadFromJSON(window.excelData);
    }

    When you open excel file, it need to be read and converted to client side Spreadsheet model. The converted client side Spreadsheet model is sent as JSON which is used to render Spreadsheet. Similarly, when you save the Spreadsheet, the client Spreadsheet model is sent to the server as JSON for processing and saved. Server configuration is used for this process.

    Open

    The Spreadsheet can open excel documents as like excel application with its data, style, format. To enable open option in Spreadsheet set AllowImport option to true. Since Spreadsheet uses a server side helper to open document, set ImportMapper in ImportSettings to map server action.

    @(Html.EJ().Spreadsheet<object>("Spreadsheet")
        .AllowImport(true)
        .ImportSettings(import =>
        {
            import.ImportMapper("Import");
        })
    )
    namespace MVCSampleBrowser.Controllers
    {
        public partial class SpreadsheetController : Controller
        {
            public ActionResult Default()
            {
                return View();
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public ActionResult Import(ImportRequest importRequest)
            {
                return importRequest.SpreadsheetActions();
            }
        }
    }

    Following file types can be opened in Spreadsheet

    • XLS
    • XLSX
    • CSV

    Click here to view online demo sample. You can open excel documents in following ways

    1. Initial settings
    2. Methods
    3. User Interface

    Initial settings

    The Spreadsheet can load excel documents initially. The document can be specified either from client side or in server side. To load excel documents initially from client side, set ImportUrl in ImportSettings. The code snippets for document initial load on client side are as follows,

    @(Html.EJ().Spreadsheet<object>("Spreadsheet")
        .ImportSettings(import =>
        {
            import.ImportMapper("Import").ImportUrl("http://mvc.syncfusion.com/Spreadsheet/LargeData.xlsx");
        })
    )
    namespace MVCSampleBrowser.Controllers
    {
        public partial class SpreadsheetController : Controller
        {
            public ActionResult Default()
            {
                return View();
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public ActionResult Import(ImportRequest importRequest)
            {
                return importRequest.SpreadsheetActions();
            }
        }
    }

    To load excel documents initially from server side, set ImportOnLoadas true and assign document stream or URL in the server. The code snippets for document initial load from server side are as follows,

    @(Html.EJ().Spreadsheet<object>("Spreadsheet")
        .ImportSettings(import =>
        {
            import.ImportOnLoad(true).ImportMapper("Import");
        })
    )
    namespace MVCSampleBrowser.Controllers
    {
        public partial class SpreadsheetController : Controller
        {
            public ActionResult Default()
            {
                return View();
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public ActionResult Import(ImportRequest importRequest)
            {
                importRequest.Url = "http://mvc.syncfusion.com/Spreadsheet/LargeData.xlsx";
                return importRequest.SpreadsheetActions();
            }
        }
    }

    Loading excel documents

    Methods

    To open an excel document, import method should be called with import options as a parameter. The Spreadsheet can open excel document as a stream or file URL.

    Stream

    Spreadsheet can open excel document as a stream and the document stream was either from the client side or it can be specified in server side. The code snippets to open excel document as a stream from client side are as follows,

  • javascript
  • function fileOpen(args) {
        var excelObj = $("#Spreadsheet").data("ejSpreadsheet"),
        stream = args.files[0]; // file stream from ejUploadbox
        excelObj["import"]({ file: stream });
    }

    The Code snippets to specify excel document as stream in server side are as follows,

  • c#
  • namespace MVCSampleBrowser.Controllers
    {
        public partial class SpreadsheetController : Controller
        {
            public ActionResult Default()
            {
                var DataSource = new OrderItemsDataContext().GetAllItemDetails.ToList();
                ViewBag.Datasource = DataSource;
                return View();
            }
     
            [AcceptVerbs(HttpVerbs.Post)]
            public ActionResult Import(ImportRequest importRequest)
            {
                importRequest.FileStream = getFileStream(); // assign file stream
                return importRequest.SpreadsheetActions();
            }
        }
    }

    File URL

    Spreadsheet can open excel document from specified URL. The URL can be specified either from client side or in server side. The code snippets to open excel document as URL from client side are as follows,

  • javascript
  • function fileOpen() {
        var excelObj = $("#Spreadsheet").data("ejSpreadsheet");
        excelObj["import"]({Url: "http://mvc.syncfusion.com/Spreadsheet/LargeData.xlsx"});
    }

    The Code snippets to specify excel document as URL in server side are as follows,

  • c#
  • namespace MVCSampleBrowser.Controllers
    {
        public partial class SpreadsheetController : Controller
        {
            public ActionResult Default()
            {
                return View();
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public ActionResult Import(ImportRequest importRequest)
            {
                importRequest.Url = "http://mvc.syncfusion.com/Spreadsheet/LargeData.xlsx";
                return importRequest.SpreadsheetActions();
            }
        }
    }

    User Interface

    You can dynamically open excel document by clicking the file menu in ribbon and choose Open to upload excel file.

    Save

    The Spreadsheet can save its data, style, format into an excel file. To enable save option in Spreadsheet set AllowExporting option in ExportSettings as true. Since Spreadsheet uses server side helper to save documents set ExcelUrl in ExportSettings option.

    @(Html.EJ().Spreadsheet<object>("Spreadsheet")
        .ExportSettings(export =>
        {
            export.AllowExporting(true).ExcelUrl("ExportToExcel").CsvUrl("ExportToCSV").PdfUrl("ExportToPDF");
        })
    )
    namespace MVCSampleBrowser.Controllers
    {
        public partial class SpreadsheetController : Controller
        {
            public ActionResult Default()
            {
                return View();
            }
            
            [AcceptVerbs(HttpVerbs.Post)]
            public void ExportToExcel(string sheetModel, string sheetData, string password)
            {
                if (String.IsNullOrEmpty(password))
                    Spreadsheet.Save(sheetModel, sheetData, "sample", ExportFormat.XLSX, ExcelVersion.Excel2013);
                else
                    Spreadsheet.Save(sheetModel, sheetData, "sample", ExportFormat.XLSX, ExcelVersion.Excel2013, password);
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public void ExportToCsv(string sheetModel, string sheetData)
            {
                Spreadsheet.Save(sheetModel, sheetData, "sample", ExportFormat.CSV);
            }
    
            [AcceptVerbs(HttpVerbs.Post)]
            public void ExportToPdf(string sheetModel, string sheetData)
            {
                Spreadsheet.Save(sheetModel, sheetData, "sample", ExportFormat.PDF);
            }
        }
    }
