CSV Data Cleaning and Python Automation
Taiwan
About me
Turn messy CSV files into consistent, usable data. My service covers duplicate detection, formatting standardization, validation, and small Python tools for repeatable file-processing tasks. Deliverables can include cleaned files, an exception list, a change log, and a reusable script with clear instructions. Ambiguous values are flagged for your review rather than guessed. Share a sample and your rules so we can agree on scope and acceptance checks before starting.
