About this Gig

Get monthly and product sales totals, with questionable rows kept in a separate issue list. I combine 1-3 CSVs in the exact seven-column layout below, up to 100 data rows total, covering all supplied months.


Receive an XLSX workbook, combined CSV, issues CSV, and notes. Each row keeps its source file and row number. I hold duplicate IDs, invalid dates, missing products, and amount mismatches for review. Source total = accepted total + held total. Editing inputs later requires a new run.


Required header:

order_id,order_date,market,product,quantity,unit_price_usd,amount_usd


Use UTF-8, YYYY-MM-DD dates, whole-number quantities, and USD amounts with up to 2 decimals. IDs must identify one row within the agreed scope. Multiple product lines sharing a valid order ID, other layouts, refunds, tax, shipping, and currency conversion are outside this offer.


Please message me before ordering with a redacted header and sample row. I use OpenAI Codex to assist processing and checking; data or screenshots may be sent to OpenAI. We agree storage, retention, and any Google Sheets use before you send real files. Remove customer names and contact details.
