Import, export, copy between instances, and generate test data that looks real.

Getting data in and out is the part of a database client people use every week and nobody writes about. Extended JSON, CSV, Excel and NDJSON, with the BSON types preserved end to end.

The export dialog with a format choice, a document limit, and a MongoDB filter, with the format options expanded

What it does

  • Export the loaded result or every matching document, as JSON, Extended JSON, NDJSON or CSV. Excel and whole-database import and export need Pro
  • Copy a collection to another instance, and duplicate a whole database, both on Pro
  • Schema analysis samples a collection and maps every field, its types, how often it occurs, and its detected enums. Free samples 500 documents
  • Generate documents from 17 Faker categories, previewed before anything is written. Up to 100,000 on Pro, 500 on Free
  • ObjectId, Date, Long, Decimal128, UUID and Binary survive the round trip
The Copy Collection dialog copying Production / shop / orders into Staging / shop / orders, with a write mode of insert and a copy-indexes option
