Importing and Exporting Data (CSV, JSON)
Explore how to manage MongoDB data by importing from CSV and JSON files and exporting collections back to these formats. Understand commands and options to efficiently load, share, and back up data.
Why do we import and export data?
Importing allows us to load data into MongoDB (or any other database) from files created in other systems like spreadsheets, other databases, or APIs that export JSON or CSV. This is useful when we want to:
Start a new project using existing data.
Combine data from different sources into MongoDB.
Quickly populate a collection for testing or development.
On the other hand, exporting lets us save MongoDB data into files that can be:
Shared with teammates or stakeholders.
Used for backups.
Analyzed using external tools like Excel, Python, or R. ... ...
