You will want to use Office.context.document.getFileAsync(...) .

See http://dev.office.com/reference/add-ins/shared/document.getfileasync for more info.

Copying one of the samples from that page:

function getDocumentAsCompressed() {
    Office.context.document.getFileAsync(Office.FileType.Compressed, { sliceSize: 65536 /*64 KB*/ }, 
        function (result) {
            if (result.status == "succeeded") {
                // If the getFileAsync call succeeded, then
                // result.value will return a valid File Object.
                var myFile = result.value;
                var sliceCount = myFile.sliceCount;
                var slicesReceived = 0, gotAllSlices = true, docdataSlices = [];
                app.showNotification("File size:" + myFile.size + " #Slices: " + sliceCount);

                // Get the file slices.
                getSliceAsync(myFile, 0, sliceCount, gotAllSlices, docdataSlices, slicesReceived);
            }
            else {
                app.showNotification("Error:", result.error.message);
            }
    });
}

function getSliceAsync(file, nextSlice, sliceCount, gotAllSlices, docdataSlices, slicesReceived) {
    file.getSliceAsync(nextSlice, function (sliceResult) {
        if (sliceResult.status == "succeeded") {
            if (!gotAllSlices) { // Failed to get all slices, no need to continue.
                return;
            }

            // Got one slice, store it in a temporary array.
            // (Or you can do something else, such as
            // send it to a third-party server.)
            docdataSlices[sliceResult.value.index] = sliceResult.value.data;
            if (++slicesReceived == sliceCount) {
               // All slices have been received.
               file.closeAsync();
               onGotAllSlices(docdataSlices);
            }
            else {
                getSliceAsync(file, ++nextSlice, sliceCount, gotAllSlices, docdataSlices, slicesReceived);
            }
        }
            else {
                gotAllSlices = false;
                file.closeAsync();
                app.showNotification("getSliceAsync Error:", sliceResult.error.message);
            }
    });
}

function onGotAllSlices(docdataSlices) {
    var docdata = [];
    for (var i = 0; i < docdataSlices.length; i++) {
        docdata = docdata.concat(docdataSlices[i]);
    }

    var fileContent = new String();
    for (var j = 0; j < docdata.length; j++) {
        fileContent += String.fromCharCode(docdata[j]);
    }

    // Now all the file content is stored in 'fileContent' variable,
    // you can do something with it, such as print, fax...
}
