About me
I help small businesses organize and compare supplier spreadsheets in CSV and Excel formats. My services focus on structured data cleanup, price-change comparisons, duplicate SKU checks, missing-row identification, and clear summary reports.
I use a careful, file-only workflow and do not require access to your online store or private accounts. I value clear scope, accurate communication, and practical deliverables that clients can review before making business decisions.
