Methods

cancelAsync

  • cancelAsync(done?: Object): void

  • Cancels the export started by the saveAsync method.

    Parameters

    • Optional done: Object

      Callback invoked when the method finishes executing.

    Returns void

load

  • load(data: string | ArrayBuffer, includeStyles?: boolean): void

  • Loads from ArrayBuffer, base-64 string or data url. This method works with JSZip version 2.* only.

    For example:

    // This sample opens an xlsx file chosen from Open File
// dialog and creates a workbook instance to load the file.
 
// HTML
<input type="file"
    id="importFile"
    accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
/>
 
// JavaScript
var workbook, // receives imported IWorkbook
    importFile = document.getElementById('importFile');
 
importFile.addEventListener('change', function () {
    loadWorkbook();
});
 
function loadWorkbook() {
    var reader,
        workbook,
        file = importFile.files[0];
    if (file) {
        reader = new FileReader();
        reader.onload = function (e) {
           workbook = new wijmo.xlsx.Workbook(),
           workbook.load(reader.result);
        };
        reader.readAsDataURL(file);
    }
}

    Parameters

    • data: string | ArrayBuffer

      ArrayBuffer or base-64 string that contains the xlsx file content.

    • Optional includeStyles: boolean

      Indicates whether styles should be imported from xlsx file. The default value is true.

    Returns void

loadAsync

  • loadAsync(data: string | ArrayBuffer, onLoaded: Object, onError?: Object, includeStyles?: boolean): void

  • Loads from ArrayBuffer or base-64 string or data url asynchronously. This method works with JSZip version 3.* only.

    Parameters

    • data: string | ArrayBuffer

      ArrayBuffer or base-64 string that contains the xlsx file content.

    • onLoaded: Object

      This callback provides an approach to get an instance of the loaded workbook. Since this method is an asynchronous method, user is not able to get instance of the loaded workbook immediately. User has to get the instance through this callback. This has a single parameter, instance of the loaded workbook. It will be passed to user.

    • Optional onError: Object

      This callback catches error information when loading. This has a single parameter, the failure reason. Return value is be passed to user, if he wants to catch the load failure reason.

      For example:

      workbook.loadAsync(base64, function (workbook) {
     // User can access the loaded workbook instance in this callback.
     var app = worksheet.application ;
     ...
}, function (reason) {
     // User can catch the failure reason in this callback.
     console.log('The reason of load failure is ' + reason);
});
    • Optional includeStyles: boolean

      Indicates whether styles should be imported from xlsx file. The default value is true.

    Returns void

save

  • save(fileName?: string): string

  • Saves the book to a file and returns a base-64 string representation of the book. This method works with JSZip version 2.* only.

    For example, this sample creates an xlsx file with a single cell:

    function exportXlsx(fileName) {
    var book = new wijmo.xlsx.Workbook(),
        sheet = new wijmo.xlsx.WorkSheet(),
        bookRow = new wijmo.xlsx.WorkbookRow(),
        bookCell = new wijmo.xlsx.WorkbookCell();
    bookCell.value = 'Hello, Excel!';
    bookRow.cells.push(bookCell);
    sheet.rows.push(bookRow);
    book.sheets.push(sheet);
    book.save(fileName);
}

    The file name is optional. If not provided, the method still returns a base-64 string representing the book. This string can be used for further processing on the client or on the server.

    Parameters

    • Optional fileName: string

      Name of the xlsx file to save.

    Returns string

    A base-64 string that represents the content of the file.

saveAsync

  • saveAsync(fileName?: string, onSaved?: Object, onError?: Object, onProgress?: Object): void

  • Saves the book to a file asynchronously. This method works with JSZip version 3.* only.

    Parameters

    • Optional fileName: string

      Name of the xlsx file to save.

    • Optional onSaved: Object

      This callback provides an approach to get the base-64 string that represents the content of the saved workbook. Since this method is an asynchronous method, user does not get the base-64 string immediately. User has to get the base-64 string via this callback. This has a single parameter, the base-64 string of the saved workbook. It will be passed to user.

    • Optional onError: Object

      This callback catches error information when saving. This has a single parameter, the failure reason. Return value will be passed to user, if he wants to catch the save failure reason.

    • Optional onProgress: Object

      Callback function that gives feedback about the progress of a task. The function accepts a single argument, the current progress as a number between 0 and 100.

      For example:

      workbook.saveAsync('', function (base64){
     // User can access the base64 string in this callback.
     document.getElementByID('export').href = 'data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' + 'base64,' + base64;
}, function (reason){
     // User can catch the failure reason in this callback.
     console.log('The reason of save failure is ' + reason);
});

    Returns void
