Excel & CSV Product Data QA — 25 SKUs
Up to 25 buyer-authorized SKUs/rows in one CSV or XLSX file. I check missing fields, duplicate keys, inconsistent names/categories and formatting; deliver a cleaned COPY, a traceable before/after change log and an exception list, with one revision. Original source remains untouched. Buyer supplies data and approves deduplication rules. No admin access or paid tools; extra rows quoted separately. Portfolio examples are synthetic demos.
Proofreading QA - 1,000 Words (EN/ES)
Proofread up to 1,000 words of buyer-authorized English or Spanish text for spelling, grammar, punctuation, consistency and formatting. Deliver the edited copy, a traceable change log and short notes. One revision within the agreed scope. Excludes legal/medical certification, translation, external fact checking, and writing new content. Buyer supplies an editable file; portfolio samples are synthetic, not prior client projects. Start only after scope and payment protection are confirmed.
About me
I provide AI-assisted data quality checks, public-source research and documented spreadsheet workflows. I review buyer-authorized CSV and Excel files, flag duplicates and missing fields, normalize data under agreed rules, and return traceable issue logs. My portfolio examples are synthetic demonstrations, not previous client engagements. I confirm scope, permissions, milestones and payment protection before starting.
