Prepare the apples: Toss the cubed apples with the lemon juice to prevent browning.
Make the dressing: In a large bowl, whisk together the mayonnaise and brown sugar until smooth.
Combine ingredients: Add the apples, celery, grapes, pecans, and cranberries to the bowl. Stir until everything is evenly coated with the dressing.
Chill: Cover the salad and refrigerate for at least 30 minutes before serving to allow the flavors to meld.
