Generate a valid MongoDB ObjectId with a root timestamp. We handle timezone offsets automatically (e.g., Z or +05:30).

Mock MongoDB ObjectId

Wait, what is this?
The first 4 bytes of an ObjectId represent the seconds since the Unix epoch. The remaining 8 bytes are typically a machine identifier, process id, and counter. This tool generates a totally random 8-byte hexadecimal string for the tail to provide a structurally valid ObjectId you can use for mocking or database manipulation.
