Messy CSV exports should not slow down analysis or system imports.I built the CSV Cleanup & Validation Toolkit to standardize headers, trim inconsistent spacing, remove exact duplicates, check required fields, flag duplicate keys, and generate a clear issue report. It runs with Python 3.9+ and requires no third-party packages.Explore the toolkit: https://contra.com/products/hD2ajF0B-csv-cleanup-and-validation-toolkit#Python #DataCleaning #Automation #CSV

Hi, I'm Kauê, a full stack developer from Brazil 👋
I build Python automations, web scrapers and complete web apps: REST APIs in Go and Python with React or Vue on the front end.
If you have a task someone on your team does by hand every week, there's a good chance a script can do it in minutes.
Open for new projects. Send me a message with what you need!
Great
Multi-source web scraper with fallback
Exact duplicates and conflicting IDs need different treatment.
CSV Exact Audit is now available: a local Python toolkit for analysts and freelancers who need a repeatable check on CSV exports.
The synthetic demo has 12 input records: 5 in cleaned.csv, 5 flagged for review, and 2 exact duplicates logged separately. Leading zeros are preserved as cell strings. Conflicting or blank IDs are flagged for review; values are not guessed or silently merged.
Included: reusable Python source, run instructions, tests, synthetic examples, three result CSVs, a JSON audit, and an original-byte backup. Processing stays on your machine; no API key or extra packages are needed.
$19 one-time. Requires Python 3.10+ and a terminal. Verified on macOS; Windows and Linux are not natively tested for this release. Scope is one UTF-8 CSV at a time, exact duplicates and optional ID review.
AI assisted code development and testing. The example is synthetic, not customer data.
