Can I get an ObjectId for a specific date?

Yes. Turn on "Use specific date" and pick a date and time. Only the timestamp portion of the ObjectId is fixed to that moment; the rest stays random, since a real ObjectId always has some randomness built in.

What does "Wrap as ObjectId(\"...\")" do?

It wraps each value in the constructor syntax used by the MongoDB shell and most drivers, so you can paste the result straight into a query or script instead of just the raw hex string.

Can I generate more than one at a time?

Yes, set Count to however many you need (up to 1000 per batch) and click Generate.

Is my data stored anywhere?

No. ObjectIds are generated on request and are not logged or saved.

Generated ObjectIds

What is a MongoDB ObjectId generator?

Generate one or many MongoDB ObjectIds at once, optionally pinned to a specific date, and copy them either as plain hex strings or wrapped in the ObjectId("...") constructor syntax used by the Mongo shell and drivers.

Useful for seeding test data, building queries that filter by a date range (since the timestamp is embedded in every ObjectId), or just checking what an ObjectId for a given day looks like.

Already have an ObjectId and want to see what's inside it instead? Try the ObjectId decoder.
