I will clean, deduplicate and standardize your messy CSV or excel data

Messy spreadsheets slow you down: duplicate rows, mixed date formats, broken columns, inconsistent names, stray spaces. I will clean your CSV, XLSX or Google Sheets file and return a tidy version plus a short change log, so you can see exactly what was changed. What I do: I remove exact and near-duplicate rows (rules agreed with you). I standardize dates, numbers, currencies and capitalization. I split or merge columns and fix encoding problems (accents, special characters). I check a sample of the result manually before delivery. What I do NOT do: I do not handle files with sensitive personal data (health, ID numbers, payment cards). Please remove or anonymize it before ordering. Note: this is a data cleaning service. It does not include macros, buttons or forms, even though Fiverr's package fields show a minimum of 1. How I work: I use scripts and AI-assisted tools and review every delivery myself. I use your files only to complete your order and delete them after delivery. Please send the file (or a 20-row sample if it is large) and tell me the rules: which columns matter and what counts as a duplicate.
