About this service
Is your spreadsheet full of duplicates, broken phone numbers and inconsistent address formats? Messy data breaks automations and ruins analysis. I process your Excel and CSV files so your dataset is clean, normalized and ready to use.
What you get
⭐ Duplicate removal and data normalization
⭐ Phone number and address formatting
⭐ Column splitting and text validation
⭐ A documented rule protocol in Markdown
⭐ A before and after change log
My process
- You send the file and I run a free data profile to find issues.
- I propose the cleaning rules and we agree on the logic before I start.
- I build a custom pandas pipeline to clean, validate and output the final file.
Why this service?
You receive a clean handover with a documented rule protocol explaining every change. AI tools assist my coding but every delivery is individually built and human checked. Revisions are included if rules need tweaking.
AI-assisted production, human review: we use AI tools to draft and produce, and a person checks your delivery against your brief before it is released. See the terms.
What we check before delivery
- Row count matches expectation after deduplication.
- Phone numbers follow requested format.
- Names are properly capitalized.
- Addresses normalized according to agreed rules.
- No missing values in required columns.
- Change log generated and reviewed.
- Markdown rule protocol included.
- Output file opens without corruption.

Questions
What access do you need to my data?
I only need the file upload. No dashboard or account access required.
How do revisions work?
If a rule needs tweaking or a format is wrong, I will adjust the pipeline based on the agreed rules.
What file formats do you accept?
Excel (xlsx, xls) and CSV. I also deliver in these formats unless you specify otherwise.
Who owns the output data?
You own all rights to the output data. I delete files from my workspace after delivery.
Do you use AI tools for this work?
Yes, I use AI to assist in writing the data processing code. The logic is human designed and the final output is manually checked for quality.
