About this Gig

Do you have an Excel or CSV file with duplicates, inconsistent formatting, invalid values, or records that should not be changed silently? I will clean and validate a bounded dataset using agreed rules. I can standardize obvious formatting, handle exact duplicates, check required fields or value rules, and separate ambiguous records for review instead of guessing. Depending on the package, you receive: - a cleaned Excel/CSV file; - explicit validation and duplicate handling; - exception notes or a review report for ambiguous rows; - a concise before/after or QA summary. This service is best for business lists, exports, reporting inputs, catalogue-style data and other structured spreadsheets where the desired rules can be stated clearly. Not included in the fixed packages: production PDF/OCR extraction, web scraping, dashboards, advanced analytics, macros/VBA, ERP integration or unlimited manual research. Please provide the source file and the rules that matter before work starts.
