About this Gig
Is your data full of duplicates, missing values, or inconsistent formats? I'll fix it.
I'm Joshua, a data analyst working daily with retail sales data I've processed and structured datasets of over 150,000 customer records for segmentation models and sales reporting. If your data is messy, I know exactly what that looks like and how to fix it.
What I'll clean and fix:
- Duplicate rows
- Missing and null values
- Inconsistent date formats
- Mixed text casing and special characters
- Incorrect data types
- Outliers and invalid entries
What you'll receive:
- A clean, analysis-ready file (CSV or Excel)
- A before/after summary report showing exactly what was found and fixed
- (Premium) A documented Python script you can reuse on future datasets
Most of the files I receive have at least three of the issues listed above combined. That's normal and fixable.
How it works:
- You share your file and tell me what the data is about
- I assess it and confirm the scope
- You receive the clean file within the agreed timeframe
All data is treated with full confidentiality.
Not sure if your data qualifies? Send me a sample I'll tell you exactly what needs fixing before you order anything.

FAQ
What file formats do you accept?
CSV, Excel (.xlsx), or Google Sheets export. For other formats, message me first.
What counts as a revision?
A revision covers corrections within the original scope. New columns, additional datasets, or changed requirements are considered a new order.
Can you handle sensitive business data?
Yes. Your data is used solely for this project and never shared with third parties.
What if my dataset is larger than 10,000 rows?
Message me before ordering and I'll send you a custom offer.
What does the Python script add-on include?
The full script used to clean your specific dataset, with comments explaining each step. Works on future files with a similar structure.
