Just wanted to post an actual answer for people struggling with this.

If you are exporting using the excel button, you can use the customizeData button property to format the data going to excel a moment before it exports.

I used this to make a synchronous api call to my server to get the data, return it, massage it, and then let it continue on it's way. Code below.

                           {
                extend: 'excel',
                customizeData: function (p)
                {
                    //get the params for the last datatables ajax call
                    var params = JSON.parse(options.dataTable.ajax.params());
                    //flag to tell the server to ignore paging info and get everything that matches the filter
                    params.export = true;
                    UC.Api(options.api.read.getHook(), params, function (data)
                    {
                        p.body = new Array();
                        $.each(data.data, function (i, d)
                        {
                            var item = [d.serial, UC.FormatDateToLocal(d.meta.Date), d.transmission.title, d.transmission.type, d.transmission.information];
                            p.body.push(item);
                        });
                    }, null, { async: false });
                }
            },
