How To Export Azure Cosmos DB Data to CSV
Get deep insights into your CSV data with Sourcetable AI. Create custom charts, formulas, and reports. No Excel skills required.
Introduction
Exporting data from Azure Cosmos DB to a CSV file is a crucial step for data analysis and reporting. This process involves using tools and scripts to extract and convert data into the widely-supported CSV format.
In this guide, we will walk you through the steps required to export your Azure Cosmos DB data efficiently. You'll also learn how Sourcetable can help you analyze your exported data with AI using a user-friendly spreadsheet interface.
Exporting Azure Cosmos DB Data to CSV Format
- Azure Storage Explorer is a free, Microsoft-supported tool that facilitates the export of Azure Cosmos DB data to CSV. Users can browse the storage account, click on the table storage they wish to export, and look for the export option to initiate the process.
- The Azure.Data.Tables SDK enables developers to export Azure Cosmos DB data to CSV using code. This method allows data to be exported either to a local file or directly to Azure BLOB Storage. The SDK can accomplish this task in just a few lines of code, making it a highly efficient solution.
- The Azure DocumentDB Data Migration Tool can be used to export data from Azure Cosmos DB. This tool allows users to export data as a JSON file, but it is best for when exporting data from DocumentDB collections. Users must select "JSON file" as the target format during the export process.
- Creating a custom export application using one of the existing language SDKs or making direct REST API calls is another method to export data from Azure Cosmos DB. Additionally, libraries like CsvHelper can be utilized to programmatically write the exported data to a CSV file.
- Azure Data Factory can be employed for data movement activities, driving the migration of data from DocumentDB to various other destinations. This is particularly useful for complex data export tasks requiring extensive control and customization.

How to Export Azure Cosmos DB Data to CSV Format
Using Azure Storage Explorer
Azure Storage Explorer is a free and Microsoft-supported tool that allows you to export data from Azure Cosmos DB to CSV files. To use it, open Azure Storage Explorer and browse to your storage account. Click on the table storage you want to export, and look for the export option in the explorer toolbar.
Using the Azure.Data.Tables SDK
The Azure.Data.Tables SDK provides a code-based solution to export Azure Cosmos DB data to CSV. This SDK can export data in a few lines of code, either to a local file or directly to Azure BLOB Storage. This method is efficient and customizable for developers familiar with coding.
Additional Tools and Libraries
You can also use other libraries like CsvHelper along with the Azure.Data.Tables SDK to write custom code for exporting data from Azure Cosmos DB. This approach can offer flexibility and additional functionality, catering to specific export requirements.
Data Migration Tool
The Azure DocumentDB Data Migration Tool is another option for exporting data from Azure Cosmos DB. Although it primarily exports data as JSON files, this tool can be part of a larger workflow where JSON data is subsequently converted to CSV format.
Azure Data Factory
Azure Data Factory is a robust solution for moving data from Cosmos DB to various destinations. While it doesn't directly export data to CSV, it can be used to transfer data to environments where CSV export is possible. Coupled with other tools, it provides a comprehensive data movement strategy.
Custom Export Applications
Developers can write custom export applications using existing language SDKs or direct REST API calls to export data from Azure Cosmos DB. This offers the most flexibility and can cater to specific business requirements.
