Messy spreadsheet or CSV? I will turn one clearly scoped file into a cleaner, consistent, analysis-ready dataset.
Base $25 scope
- 1 CSV or XLSX file
- Up to 5,000 rows and 15 columns
- Duplicate detection/removal using agreed rules
- Normalize dates, numbers, whitespace, casing and common text formats
- Identify missing or inconsistent values
- Basic validation checks for agreed columns
- Cleaned file + concise change/quality summary
I will preserve the original file and will not silently alter protected columns.
If the dataset is larger, requires manual research/enrichment, complex formulas, database work or custom business logic, please message me first so I can confirm the scope.
Deliverables:
- Cleaned CSV/XLSX
- Duplicate handling
- Format normalization
- Missing/inconsistent value flags
- Before/after quality summary
- Optional reusable cleanup script when useful
