You will get clean and structured Excel or CSV dataset
Project details
Got a messy spreadsheet full of duplicates, broken formats, or missing values? I'll clean it thoroughly and deliver a structured, analysis-ready file with a full written summary of every change made.
What sets my work apart is process. Before touching a single cell, I profile the entire dataset identify data types, flag all anomaly categories, and map the cleaning logic. You don't just get a cleaner file, you get a documented one. Every fix is transparent and auditable.
I work with Excel, CSV, and Google Sheets using Power Query, Pandas (Python), and formulas so whether your dataset has 500 rows or 100,000, I have the right tool for it.
What you receive:
→ Cleaned and formatted dataset in your preferred format
→ Duplicates removed and flagged
→ Missing values handled with logic, not deleted blindly
→ Column structure standardized and consistent
→ Written change summary documenting every transformation
Message me before ordering if you have a large or complex file — I'll confirm the scope and timeline upfront so there are no surprises.

About Muzammil
Data Cleaning Specialist | Excel & Python | B2B Lead Enrichment
Ghotki, Pakistan - 6:25 am local time
I am a Data Cleaning and Enrichment Specialist who turns disorganized, error-filled lead lists and databases into structured, ready-to-import files your sales team can actually use.
I don't just clear data blindly—I have managed end-to-end outbound outreach campaigns myself. Because I maintain my own tracking sheets and use Apollo regularly, I deeply understand the mechanics of sequencing software. I know that an uncleaned emoji in a first name or a messy corporate suffix ($Inc.$, $LLC$) destroys response rates, and unverified emails ruin your domain health.
Additionally, I bring a background in nursing science, which gives me exceptional attention to detail, strict compliance habits, and a strong understanding of medical and professional terminology when handling complex datasets.
What I do for your B2B Lead Lists & Data:
→ Lead Enrichment: Clean raw Sales Navigator exports and map verified business emails and phone numbers.
→ Data Hygiene: Strip out titles, credentials, emojis, and regional brackets so your custom variables read 100% naturally.
→ Format Standardization: Fix inconsistent formatting across phone numbers, dates, and locations.
→ Deliverability Protection: Actively verify email deliverability and flag catch-alls to protect your email infrastructure from bounces.
Tools I Master:
•Enrichment: Apollo, Sales Navigator, Google Sheets, CSV processing
• Data Cleaning: Excel (Power Query, advanced formulas, pivot tables) & Python
(Pandas/NumPy for automated or large-scale cleaning)
I treat every dataset with the absolute highest level of accuracy, structure, and professional confidentiality.
Message me with a brief description of your data goals or send over a messy sample list—I will respond within a few hours with a clear strategy, timeline, and price.
