ObjectId Input

Decoded Details

Timestamp, random value and counter for each ObjectId will appear here

Date to Boundary ObjectId

MongoDB's _id sorts chronologically, so a query like { _id: { $gte: minId, $lt: maxId } } filters by creation time with no index scan. These boundaries have the real timestamp and an all-zero or all-f remainder.

About MongoDB ObjectId Decoder

Decode a MongoDB ObjectId into its creation timestamp, per-process random value and counter, or work out the boundary ObjectId for a date to use in a range query.

Key Features

Extracts the embedded creation timestamp from the first 4 bytes of any ObjectId
Reads the 5-byte random value and 3-byte counter from the current unified driver spec
Accepts bare hex or the ObjectId("...") format pasted from the mongo shell or Compass
Decodes many ObjectIds at once, with the invalid ones flagged inline
Computes the min and max boundary ObjectId for a date, ready to paste into a range query

Use Cases

Find out when a document was created with no created_at field
Build an efficient _id-based range query for a date without scanning a secondary index
Confirm a client library is generating well-formed ObjectIds rather than a lookalike string
