I will clean and merge your excel or CSV files with a validation report

Are your monthly exports hard to combine? I will merge buyer-supplied Excel or CSV files into one tidy table using agreed column mappings and duplicate rules. You receive the cleaned file, an exceptions sheet for uncertain records, reconciled before-and-after row counts, and a concise change report. Package limits apply to combined source rows and files. Basic includes up to 2 cleanup rules, Standard 4, and Premium 6. One rule means one transformation such as date normalization, a column rename, or a duplicate policy. Ambiguous values are flagged rather than guessed. Please provide source files, target columns, a matching key, and your duplicate policy. Account access, scraping, and live integrations are outside this service. I use scripted and AI-assisted checks, with final work reviewed before delivery.
