The PivotGrid control extends the FlexGrid, so you can export its contents to XLSX files in the same way you would export regular FlexGrid controls.

We'll create a client-side JavaScript function to build the XLSX file you want. You have complete control of the output. For example, you may add sheets containing the current view, any pre-defined views, and the raw data. Here’s an example:

 function exportToXlsx() {
        // create book with current view
        var book =, {
            includeColumnHeaders: true,
            includeRowHeaders: true
        book.sheets[0].name = 'Main View';
        // add sheet with raw data
        if (theRawGrid.rows.length <= 20000) {
            var raw =, {
                includeColumnHeaders: true,
                includeRowHeaders: false
            raw.sheets[0].name = 'Raw Data';
        // save book'olap.xlsx');
