Mongodb sort with case insensitive manner

Create the collection with a default collation by this way you can order by any property with case insensitive.

db.createCollection("collection_name", { collation: { locale: 'en_US', strength: 2 } } )

db.getCollection('collection_name').find({}).sort( { 'property_name': -1 } )

More info: https://docs.mongodb.com/manual/core/index-case-insensitive/

You need to use collation here with locale: "en"

db.collection.find({}).collation({ locale: "en" }).sort({ name: 1 })

So for the below document

{ "_id" : 1, "name" : "Bhavik" }
{ "_id" : 2, "name" : "Jay" }
{ "_id" : 3, "name" : "atul" }

You will get

{ "_id" : 3, "name" : "atul" }
{ "_id" : 1, "name" : "Bhavik" }
{ "_id" : 2, "name" : "Jay" }
