Importing and Exporting Data (CSV, JSON)
Understand the essential techniques to import and export data in MongoDB using CSV and JSON file formats. Learn to use mongoimport and mongoexport command-line tools to load data into MongoDB or save collections for backup, analysis, or sharing.
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. ... ...
