Excel & CSV Data Cleanup, Verification & QA

I will clean, verify and quality-check a small Excel or CSV dataset and return a ready-to-use cleaned file plus a concise summary of what was changed or flagged.

This $20 fixed-price service includes up to 500 rows, one Excel/CSV file or worksheet, and approximately 15 columns.

I can handle duplicate checking/removal, whitespace and formatting cleanup, agreed date/number/text normalization, missing or invalid-value checks, structural consistency checks, and final reconciliation against the original data.

Unclear or ambiguous records are flagged for review rather than guessed or silently changed.

You receive: • Cleaned Excel or CSV file • Change/exception summary • Final QA against the original data • One in-scope correction round • 24–48 hour turnaround

Before starting, please send a description of the problem and a few non-sensitive sample rows so I can confirm that the task fits this fixed-price scope.

Larger datasets, extensive web research, PDF/image transcription, bookkeeping, dashboards, complex macros/automation, and ambiguous record merging are outside this introductory package and can be scoped separately.

AI-assisted and data-processing tools may be used where appropriate, with human review and validation of the final result. Please do not send confidential or sensitive data until its handling requirements have been agreed.
