What is a MongoDB ObjectId?
A MongoDB ObjectId is a 12-byte identifier commonly displayed as 24 hexadecimal characters. Its structure includes a four-byte timestamp, five bytes of process-unique random data, and a three-byte counter. This structure makes ObjectIds compact and roughly ordered by creation time.
Can I use these in MongoDB?
These values follow the standard ObjectId byte layout and are suitable as ObjectId-shaped values. This page does not connect to your database or insert records; check your application's requirements before using generated values in production.
Frequently asked questions
Are ObjectIds completely random?
No. They include a timestamp and counter alongside random bytes, so they are not purely random and should not be treated as secret tokens.
Can I export multiple ObjectIds?
Yes. Generate up to 500 values, copy them, or download CSV and Excel files. Generation happens locally in your browser; the spreadsheet library is loaded only when Excel export is requested.
