What You'll Receive
Full Description
Your spreadsheet is a mess: duplicate rows, blank cells, dates written four different ways, and columns that refuse to sort. I turn it into one consistent, trusted workbook — and I send you a report sheet showing every single change, so nothing happens behind your back.
Good data cleaning is not cosmetic. It is the difference between a pivot table that lies to you and one you can actually act on. I treat your file the way an analyst would: standardize first, verify second, and document everything I touched.
WHAT YOU GET
- Duplicate rows found and removed, with fuzzy matching for near-duplicates
- Blanks and obvious errors handled or flagged for your decision
- Dates, numbers, headers and categories standardized into one consistent format
- One clean .xlsx or CSV you can pivot, filter and analyze immediately
- A QA report sheet with every delivery: what changed and what stayed
- Custom rules on request — your column order, your date format, your categories
- Large files welcome: the pipeline keeps working when the file keeps growing
COMMON JOBS
Deduplicating a CRM export, merging several monthly sheets into one, fixing a file that came out of a legacy system, standardizing addresses or phone numbers, splitting or combining columns, and rescuing a spreadsheet that somebody has been manually patching for years.
HOW IT WORKS
- Send the file, or a sample of it. I look and confirm the exact scope and price first.
- I clean it with a documented, repeatable process — not guesswork.
- You get one tidy workbook plus the change report, so you can audit the result.
PRIVACY
Your data is never shared or reused, and I delete it after delivery on request. If your file contains personal or confidential information, say so and I will handle it exactly as you instruct.
Not sure whether your file is fixable? Send a sample — I will tell you honestly what is possible before you spend anything.
