Messy spreadsheets and unverified contact lists quietly cost businesses more than most people realize — in wasted outreach, bad decisions, and hours spent copy-pasting instead of working. I offer high-accuracy data management built to turn raw, unorganized information into a clean, actionable database.
This is the service I've done the longest: high-volume data entry, deduplication, and legacy-system cleanup, with a documented 99% accuracy rate across projects ranging from small contact lists to 100,000+ record datasets processed annually.
What's Included
- High-volume CRM/database cleanup (100k+ rows)
- B2B contact verification & enrichment
- Legacy database modernization (e.g., FoxPro to Excel)
- Automated multi-source Excel/Google Sheets merging
- Deduplication with fuzzy-matching logic, not just exact matches
- PDF/image-to-Excel conversion
