You will get cleaned and validated CSV or Excel data with Python


Project details
Get a usable cleaned file plus separated issue and duplicate records, so you can see what changed and reconcile every source row.
Starter solves one immediate cleaning need and returns checked output plus exception evidence. Standard adds repeatability through a reusable Python script and run note. Advanced handles either a larger reusable multi-file automation or one defined summary report/dashboard with up to ten rules and five focused tests; the buyer chooses the primary outcome before purchase.
Send a sanitized sample, the expected columns, and your key rules so I can confirm the right output package.
This service does not include API integration, database connection, web crawling or scraping, authentication or permission systems, server deployment, OCR, manual research, password recovery, unsupported macros, or paid-source enrichment. Those are separate custom scopes, not hidden extensions of a tier.

About Junsoo
Python Data Cleaning & Automation | Web & Spring Boot
Seoul, South Korea - 8:45 am local time
I turn messy CSV or Excel files and repetitive intake work into checked outputs you can use: clean data, separated issues and duplicates, reconciliation counts, and reusable automation when the package includes it. I also build launch-ready responsive sites and diagnose focused Spring Boot failures.
I can help with:
- Python and pandas CSV/Excel cleaning with clean, issue, duplicate, and reconciliation outputs
- Inquiry workflows that validate, route to a client-owned Sheet or notification tool, and log failures
- Responsive HTML, CSS, and JavaScript business websites with a working CTA and launch publication
- Spring Boot issue diagnosis with reproduction evidence, fix feasibility, and a clear next action
My delivery process:
1. Confirm the target result, representative input, and acceptance examples
2. Build the agreed complete output or reproduce the supplied defect
3. Validate output counts, workflow paths, responsive behavior, or API responses
4. Deliver the result, source/configuration where included, evidence, and a concise handover
Portfolio note: the public examples in my profile are self-initiated demonstration projects using fictional or anonymized data, not claims of paid client work. The inquiry-triage demo uses transparent rule-based logic and no external AI service. Production integrations involving third-party APIs, AI, email, messaging, databases, or deployment are separately scoped and use client-owned accounts and credentials.
Send me a sanitized sample file, current workflow, page list, or reproducible error. I will reply with the best-matched package, the complete result it includes, and anything needed to start safely.
