ms-office - Best way to export a csv file in Excel Addin

Question

I'm a fairly new coder and trying to write a simple add-in to export an Excel table to csv format. Whilst this is easily possible using VBA, I would like to be forward thinking and use the add-in model if I can. I've looked through the API docs, but can't find anything to do it (such as SaveAs)- could anyone please offer me some pointers?

Many thanks

Tim

I'd suggest grabbing the table's range, loading its values and doing the conversion to CSV yourself.

Your code should look something like this :

Excel.run(function (ctx) { 
    var table = ctx.workbook.tables.getItem(tableName);
    var tableRange = table.getRange();
    tableRange.load('values'); 
    return ctx.sync().then(function() {
        ConvertToCSV(tableRange.values);
    });
}).catch(function(error) {
    console.log("Error: " + error);
    if (error instanceof OfficeExtension.Error) {
        console.log("Debug info: " + JSON.stringify(error.debugInfo));
    }
});

Please let me know how this works out for you.
