Automate SQL queries with a Python Lambda Function.

View Codebase »


This is a lambda function which queries an RDS database, writes the results to an Excel file, and saves the file to an S3 bucket.

Built With

Getting Started


  1. An AWS account
  2. An RDS database to run the queries against
  3. Permissions for RDS, Lambda, S3, and EventBridge (CloudWatch Events)


  1. Clone the repo
  2. Modify to match your specific environment: database connection details, queries you want to run, name your Excel sheets, name the file, and specify the S3 bucket name.
  3. If you wish to have this run on a schedule, add an EventBridge trigger and specify an interval number of days when this function is executed.


This function is very useful if you have a need to re-run the same SQL queries on a set schedule, like every week or two, or even every day. The Excel file generated could be useful to a business analyst to track any kind of change to your database: number of users, emails for a newsletter, telemetry, etc.
