Exporting SQLite Database Data to JSON in Python

If you’re working with an SQLite database and want to export your data into a JSON format, this guide is your guide. We’ll walk you through how to collect data from multiple tables in your SQLite database and write it into a well-structured JSON file using Python. Here's what you need to know!

Understanding the Challenge

The Solution

Step 1: Setting Up Your Environment

Before beginning, make sure you have Python installed on your system. You will also need to install the SQLite library (this comes built-in with Python) and the JSON library to work with JSON data.

Step 2: Writing the Code

Code Explanation

Import Required Libraries: The code starts by importing the sqlite3 and json modules necessary for database connection and JSON file handling, respectively.

Creating a Dictionary Factory: The dict_factory function allows us to convert each row fetched from the SQL query into a dictionary, where the keys are column names, making the data more accessible and structured.

Iterating Through Tables: We loop through each defined table, execute a SELECT query to fetch all records, and store the results in a dictionary under the corresponding table's name.

Conclusion

With just a few lines of code, you can extract data from multiple tables in an SQLite database and save it in a JSON format. This process not only streamlines data handling but makes it easier to share and work with outside of the database context. Now, you can confidently format your SQLite data into JSON for further applications or analysis!

Feel free to adapt this code to fit your specific requirements or expand it to include error handling or data filtering based on your needs. Happy coding!
