About this Gig
Do you have messy Excel files that are impossible to analyze? Or do you need to turn raw data into clear, actionable charts for your report?
Stop struggling with Excel formulas. As a Python Data Analyst, I use powerful libraries like Pandas, NumPy, and Matplotlib to clean your data and uncover hidden insights instantly.
What I Can Do For You:
1. Data Cleaning & Preprocessing (The most important step!)
- Handle Missing Data: Impute null values or remove incomplete rows.
- Remove Duplicates: Ensure your dataset is unique.
- Fix Formatting: Standardize dates (DD/MM/YYYY), phone numbers, and text formats.
- Merge Files: Combine multiple CSV/Excel sheets into one master dataset.
2. Data Visualization: I will create professional, publication-quality charts using Matplotlib & Seaborn:
- Bar & Column Charts (Comparisons)
- Line Charts (Trends over time)
- Heatmaps (Correlation analysis)
- Pie/Donut Charts (Composition)
- ...and Scatter Plots, Box Plots for outlier detection.
3. Deliverables:
- Cleaned Dataset (.CSV / .XLSX)
- Charts (.PNG / .JPG)
- Python Source Code (Premium Package only)
My Tech Stack:
- Python: Pandas, NumPy
- Visualization: Matplotlib, Seaborn
- Tools: Jupyter Notebook, VSCode
