Hi, I understand you need multiple Excel spreadsheets consolidated into a single clean, reliable customer dataset with duplicates removed, formatting standardized, and data quality issues identified and flagged. The goal is to ensure the final file is accurate, consistent, and easy to review directly in Excel. I will clean and merge all files using a structured process in Excel (Power Query and validation rules), standardize names, emails, phone numbers, and dates, and remove or flag duplicates and inconsistencies based on your style guide. I will also review outliers and suspicious entries carefully so nothing important is lost or incorrectly merged. You’ll receive a fully cleaned master worksheet, a clear change log showing what was corrected or flagged, and a short summary of any records requiring manual review. The final dataset will be organized, validated, and ready for immediate use after your spot-check.
