You will get clean, standardized, and deduplicated Excel or CSV data
Project details
I will clean, standardize, validate, and deduplicate your CSV or Excel data using a structured Python-based workflow.
Depending on the package, I can fix inconsistent formatting, extra spaces, missing-value markers, duplicate records, inconsistent dates, phone numbers, emails, and other rule-based data issues.
You will receive clearly organized output files and a summary of the cleaning performed. For advanced projects, I can also provide validation results, removed-record logs, change logs, and a reusable workflow for recurring datasets.
Your original files are not modified in place. Cleaning rules are confirmed before processing to avoid unintended changes to valid business, research, or operational data.

Frequently asked questions
About Ke
Next.js & Supabase Backend Developer | Stripe & API Integrations
Chinahecun, China - 12:39 pm local time
My current public implementation work includes:
• Secure webhook signature verification using raw request bodies, replay-window protection, and constant-time comparison
• Idempotent Stripe payment success and failure handling
• Supabase/PostgreSQL migrations and atomic state transitions
• Next.js and TypeScript API integration
• Automated tests, type checking, production builds, and GitHub Actions CI
• Investigation and repair of existing software projects
I am best suited for bounded backend tasks such as:
• Fixing a broken webhook or API integration
• Connecting Stripe payments to Supabase
• Repairing inconsistent database states
• Adding tests and CI to an existing project
• Debugging an inherited Next.js application
• Building a small backend integration with written acceptance criteria
My portfolio examples are public technical implementation proofs. I do not present them as confidential client deployments.
For each project, I first confirm the expected behavior, failure cases, acceptance criteria, and delivery scope. I then provide a focused implementation, tests, and a concise handoff document.
Steps for completing your project
After purchasing the project, send requirements so Ke can start the project.
Delivery time starts when Ke receives requirements from you.
Ke works on your project following the steps below.
Revisions may occur after the delivery date.
Review data and cleanup rules
I review the supplied files, confirm the requested cleanup rules, output format, duplicate keys, and any fields that must remain unchanged.
Clean and validate the data
I process the files using the agreed rules, standardize values, remove approved duplicates, flag validation issues, and verify the cleaned output.
