This project is a Python script that exports data from a CosmosDB container to a CSV file.

• Python 3.6 or higher
• Access to a CosmosDB instance
• Azure Cosmos DB SQL API SDK for Python
• python-dotenv module

Install the Azure Cosmos DB SQL API SDK for Python:

pip install azure-cosmos

Install the python-dotenv module:

pip install python-dotenv

This project uses python-dotenv to load environment variables. Create a .env file in the project root and add the following variables:

• COSMOS_DB_ENDPOINT: Your CosmosDB endpoint.
• COSMOS_DB_KEY: Your CosmosDB key.
• COSMOS_DB_DATABASE: The database to export data from.
• COSMOS_DB_CONTAINER: The container to export data from.
• OUTPUT_FILE: The name of the output CSV file. If not provided, the default is 'cosmos_data.csv'.

Clone this repository to your local machine.

Navigate to the directory containing the cosmos_exporter.py script. Set the environment variables in the .env file.

Run the script using Python.

python cosmos_exporter.py

This will create a CSV file (named as per the OUTPUT_FILE environment variable or 'cosmos_data.csv' by default) in the same directory, containing the exported data from the CosmosDB container.

The script determines all unique fields in the documents and writes the data to the CSV file accordingly. The CSV file is written in 'utf-8' encoding.
