Daily Reporting Automation
Python ETL pipeline replacing manual CSV merging.
Overview
A Python script that automates a daily, repetitive routine: collecting raw data, merging it with the previous days’ history, generating a summary, and sending the report by email. It’s built to run on a cron schedule and is configured per use case so the same pipeline can handle different sources and recipients.
Why it exists
Most marketing teams have a “morning report”: a spreadsheet someone updates every day before the standup. The work is mechanical, the schedule is unforgiving, and the output is the same shape every time. That’s exactly the kind of work scripts are good at.
Stack
Python with Pandas and NumPy for data shaping, smtplib for delivery, and a small YAML config that lets non-engineers point the script at new sources or change recipients without touching the code.
