You will get clean Excel/CSV data, validation checks and report tables
Project details
I will turn your existing Excel, CSV, or Google Sheets data into a cleaner, analysis-ready deliverable. This project is best for sales records, survey exports, operations logs, customer lists, or other spreadsheets that already exist but need validation before reporting.
Depending on the package, you will receive a cleaned file, an issue log, a simple data dictionary, and report-ready summary tables or charts. I document assumptions and flag records that need client judgment instead of silently changing the meaning of the data.
This project does not include new data collection, web scraping, dashboards, forecasting, financial audit, academic ghostwriting, or changing data to force a result.

About Yiliang
Data Cleaning, Survey Analysis and Research Reporting Specialist
Beijing, China - 9:18 am local time
My work is best suited for projects where the raw material already exists but is hard to use: inconsistent Excel files, mixed PDF/Word folders, survey data, monthly business records, public-source research materials, or fragmented business documents.
Typical deliverables include clean Excel/CSV files, data dictionaries, issue logs, summary tables, charts, source indexes, evidence tables, Word/PDF reports and repeatable workflow notes.
I do not fabricate data, write full academic papers for submission, or work with illegally obtained personal data. My focus is clean data handling, transparent assumptions and reports that can be checked back to source materials.
