About this Gig
Is your dataset messy, inconsistent, or full of errors? I will clean and preprocess your data so it is ready for analysis, reporting, or machine learning.
What I will do:
- Remove duplicates and fix inconsistent values
- Handle missing data professionally
- Standardize formats, column names, and data types
- Deliver a clean CSV file with a summary of all changes made
I work in Python (Pandas) and R, and deliver via Jupyter Notebook or R Markdown so every step is transparent and documented.

FAQ
What format should I send my data in?
CSV or Excel works best. I can also work with JSON or plain text files.
What if my dataset is larger than your package covers?
Message me before ordering and I will create a custom offer for you.
Will I understand what was changed?
Yes. Every delivery includes a written summary of all cleaning steps performed.
