You will get clean, deduplicated, and reconciled CSV or Excel data
Rising Talent
Project details
I turn inconsistent CSV/XLSX exports into clean, reviewable data without hiding ambiguous decisions. I normalize agreed fields, remove exact duplicates, reconcile two sources, flag uncertain fuzzy matches, preserve row lineage, and deliver master data, exceptions, and audit outputs. Files are processed with explicit rules and formula-safe CSV exports. Scope is capped at two files and 25,000 rows per file; ambiguous rules are confirmed before matching, and unsupported scale or additional sources receive a separate quote.

About Serhii
Google Sheets & Apps Script Workflow Automation
Калуш, Ukraine - 12:53 pm local time
In my operations work, I support processes used by teams of 40+ drivers and staff. That has made me careful about practical details: protected inputs, validation, stable IDs, status controls, exception lists, audit history, and clear handover notes.
I can help with:
• spreadsheet formulas, validation, dropdowns, cleanup, and reporting
• Forms → Sheets intake and routing
• Apps Script menus, triggers, approvals, Docs/PDF generation, and Gmail drafts
• CSV/XLSX matching, deduplication, and reconciliation
• focused Excel or Google Sheets dashboards
• small Python tools when a spreadsheet is no longer enough
For an existing system, I work in a copy first, preserve the current business logic, and agree on acceptance criteria before changing production data. For a new workflow, I define the inputs, outputs, edge cases, and ownership before building.
My portfolio contains self-initiated working demos with screenshots, source code, and documentation. Send me the current file or process, expected result, approximate row count, and deadline. I will tell you what can be delivered, what needs clarification, and the safest first milestone.
