MongoID to Timestamp Converter Guide

🔍 What is a MongoDB ObjectId?

A MongoDB ObjectId is a 12-byte unique identifier used as the default `_id` for documents. The first 4 bytes represent a timestamp, making it possible to extract the document’s creation time directly from the ObjectId.

⏳ Why Convert ObjectId to Timestamp?

  • To find when a MongoDB document was created
  • Debug and audit document creation times
  • Track data insertions and trends
  • Extract creation time without querying the database

🧪 How Does This Tool Work?

  • You paste a valid MongoDB ObjectId (24-character hex string)
  • The tool extracts the first 8 characters (timestamp in hex)
  • It converts that hex to a Unix timestamp
  • Displays the readable date and time in your local format

📥 What is a Valid MongoDB ObjectId?

A valid ObjectId must be a 24-character hexadecimal string. Any deviation (e.g. extra characters, non-hex digits) will be rejected by this tool for accuracy.
