I provide precise, fast, and reliable data cleaning and transformation services using Excel and Google Sheets. I specialize in cleaning messy e-commerce, sales, and transactional datasets: fixing date formats, correcting emails/phones, removing duplicates, normalizing text, repairing broken formulas, and preparing analysis-ready CSV/Excel files. I use Power Query, formulas (TRIM, CLEAN, TEXT, IFERROR), data validation, conditional formatting, and manual verification to ensure 100% data accuracy.
What I deliver:
• Cleaned & deduplicated Excel/CSV (before → after)
• Corrected date/time & numeric formats
• Repaired/maintained formulas and workbook structure
• Standardized customer and product fields (emails, phones, names)
• Optional: CSV export + short summary (rows processed, duplicates removed, issues fixed)
Why choose me:
• Hands-on Excel + Power Query experience for real-world datasets
• Attention to detail — every row double-checked before delivery
• Fast turnaround and clear communication
• Confidential handling of sensitive data
Typical turnaround: 1–3 days (depends on dataset size).
Tools: Microsoft Excel, Power Query, Google Sheets, basic Python (optional), data validation tools.
