Do you combine new CSV exports and repeat the same checks every week or month?


I will build a reusable Python script for one clearly defined CSV workflow: merge files, clean agreed fields, check required values, and flag duplicates. Run it again when new files arrive using the same agreed structure and rules.


You will receive:

- Python source code for your agreed file format

- A cleaned CSV and separate reports for duplicates and invalid rows

- A processing summary and an example run

- Setup and usage instructions


The starter package covers up to 5 CSV files per run, 25,000 rows combined, one shared column structure, one duplicate key, and up to 3 agreed cleaning or validation rules. Your original files remain unchanged.


Please contact me before ordering with a small anonymized sample and the output you expect. I will confirm the scope and delivery before we start.


One revision covers adjustments to the agreed workflow. New file formats, additional workflows, GUIs, web scraping, API connections, and hosting require a separate scope.
