saveJSON

Serializes the workbook in the format that is defined in the configuration. This method does not return the JSON, but a Promise object which will yield the JSON data when it is available.

This method is functionally similar to toJSON, but it is also able to save the embedded images (this is the reason why it must be asynchronous).

Returns

Promise - A Promise object which will be resolved with the JSON data.

Example

<div id="spreadsheet"></div>
<pre id="result"></pre>
<script>
    var spreadsheet = $("#spreadsheet").kendoSpreadsheet().getKendoSpreadsheet();
    spreadsheet
        .saveJSON()
        .then(function(data){
            var json = JSON.stringify(data, null, 2);
            $("#result").text(json);
        });
</script>
