What Is BSON to JSON Converter?

This tool converts MongoDB extended JSON (BSON representation) back to standard JSON. It unwraps $numberInt, $numberDouble, $numberLong, $date, $oid, and other BSON type wrappers, restoring plain JSON values.

How to Use

  1. Paste your MongoDB extended JSON into the input field.
  2. Click "Convert to JSON" to transform it back to standard JSON.
  3. Copy the clean JSON for use in other tools or applications.

Frequently Asked Questions

What BSON types are supported?

The converter handles $numberInt, $numberDouble, $numberLong, $date, $oid, $binary, $timestamp, $regex, $undefined, $null, $minKey, $maxKey, and $symbol.

Will I lose precision with large numbers?

The converter preserves numeric values as numbers. Extremely large integers from $numberLong may use string representation to avoid precision loss in JSON.
