# Introduction
The Canvas Student Data Export Tool can export nearly all of a student's data from Instructure Canvas Learning Management System (Canvas LMS).
This is useful when you are graduating or leaving your college or university, and would like to have a backup of all the data you had in canvas.
The tool exports all of the following data:
- Course Assignments
- Course Announcements
- Course Discussions
- Course Pages
- Course Files
- Course Modules
The tool will export your data in JSON format, and will organize it nicely into folders named for every term of every year.
Example:
- Fall 2013
- Econ 101
- files
- modules
- Econ 101.json
- English 101
- files
- modules
- English 101.json
- Fall 2014
- Fall 2015
- Fall 2016
- Spring 2014
- Spring 2015
- Spring 2016
- Spring 2017
- Winter 2014
- Winter 2015
- Winter 2016
- Winter 2017
- all_output.json
# Getting Started
## Dependencies
To run the program, you will need the following dependencies:
`pip install requests`
`pip install jsonpickle`
`pip install canvasapi`
Then run from the command line:
`python export.py`
## Configuration
These are the configuration parameters for the program:
- Canvas API URL
- Canvas API key
- Canvas User ID
- Directory in which to download course information to (will be created if not present)
- List of Course IDs that should be skipped
# Contribute
I would love to see this script's functionality expanded and improved! I welcome all pull requests :) Thank you!
