About this Gig
Got a messy Excel or CSV file eating your time? I do Excel data cleaning and formatting, so you get it back clean, consistent, and ready to use.
What I fix:
- Missing values
- Duplicate rows
- Wrong data types (dates or numbers stored as text)
- Messy dates, names, and text
- Inconsistent formatting
Standard and Premium also include:
- Merging or joining multiple files
- Pivots, reshaping, group-by summaries
What you get:
- Clean Excel or CSV file
- Short summary of what was changed
- Suggestions to improve the data further
- Reusable custom script (Premium)
Why me:
AI-assisted checks plus manual review, so less slips through. I work with sales, HR, finance, and ecommerce data, and I tune the cleaning to your file instead of using a template.
A merge or reshape request counts as 1 dataset, any row count.
Not sure if your file is a fit? Message me before ordering with a few sample rows (remove sensitive info) and I'll tell you how I'd handle it.

FAQ
Q1: What type of data do you clean?
I work with CSV and Excel files of any structure — sales data, customer records, financial data, marketing leads, and more. If you're unsure, just share a sample and I'll confirm.
Q2: Do you handle missing data?
Yes — missing values are automatically detected and filled using smart imputation logic based on your data type. Numeric fields use mean/median, categorical fields use mode.
Q3: Will you provide Python script?
The complete Python source code is included in the Premium package. Basic and Standard deliver the cleaned dataset only.
Q4: Can you prepare data for Power BI/Tableau?
Absolutely. The cleaned output is formatted and structured to plug directly into Power BI, Tableau, or any BI tool without any extra prep work.
Q5: Do you use AI for data cleaning?
Yes — the tool uses Groq AI (powered by LLaMA) to scan your dataset, detect quality issues, and suggest the best cleaning approach automatically. It's not just scripts — it's intelligent automation.
