Text-to-Database Upload Automation

I have a sizeable batch of raw text files that need to live in a structured database so they can be queried and analysed down the line. The core of the job is to design and execute a clean import process: parse the text, map the relevant fields, then load everything into a well-organised schema. I’m flexible on technology—MySQL, PostgreSQL, even MongoDB are all on the table—as long as the final setup is stable and easy for me to maintain or rerun if the dataset grows.

A simple command-line or Python script that:
• reads the source files from a given folder,
• validates and normalises the content,
• inserts the records without duplicates,
• logs any errors for review

will be perfect. A concise read-me explaining how to configure and execute the import rounds out the deliverable. If you’ve handled similar ETL work before and can turn this around quickly, let’s get started.
