I will clean and fix data in excel and python
About this Gig
Is your data full of blanks, duplicates, wrong formats, or random errors? I'll clean it up so it's analysis-ready fast and thoroughly.
I work with Python (Pandas) and Excel to handle real-world messy data. During my internship at Sopra Steria Solutions, I cleaned and standardized data pipelines used by senior leadership for decision-making. For a retail analytics project, I resolved 100% of missing values across 3,900+ transactions and engineered new features for segmentation.
What I'll fix in your dataset:
Missing / null values (removed, filled, or flagged your choice)
Duplicate rows
Inconsistent formats (dates, phone numbers, categories, text casing)
Wrong data types (numbers stored as text, etc.)
Outliers (detected and flagged or treated)
Column renaming and structure standardization
What you'll receive:
A fully cleaned CSV or Excel file
A short data quality report (what was found, what was changed)
For Premium: a reusable Python script so you can clean future data yourself
Tools: Python · Pandas · NumPy · Excel
Send me a sample of your data before ordering I'll confirm the scope and timeline instantly.
FAQ
What file formats do you accept?
CSV, Excel (.xlsx / .xls), and Google Sheets exports. JSON available on request.
What if my dataset is larger than 15,000 rows?
Order the Premium package or message me first — I handle large datasets via optimized Pandas pipelines and will give you a custom quote.
Will I know what changes were made?
Yes. Every order includes a data quality report listing exactly what was found and what was changed — nothing is done silently.
Can you clean data with sensitive/confidential information?
Yes. You can anonymize column names before sending. I treat all client data as strictly confidential.
