Two CSV exports: differences, duplicates & missing recordsNoah Plenter
Turn two recurring CSV exports into a clear list of records that need attention.
PILOT PRICE: $150 USD, subject to sample and scope confirmation. Message before ordering. The displayed one-week duration is an estimate; the delivery date is agreed after sample review and capacity confirmation.
WHAT YOU RECEIVE
A readable HTML exceptions report, review CSV, JSON evidence preserving source records, agreed column mapping, reproducible Python command and file hashes. Duplicate keys, invalid values and unmatched records stay visible for your decision. One consolidated revision to the agreed rules is included.
SCOPE
Two permitted UTF-8 CSV files, each up to 5,000 records and 20 MB. One exact string matching key and up to five agreed text or decimal comparison fields. Provide a small expected-output example. Start with redacted inventory, product or work-status data; no sensitive personal, health, payment-card or bank data.
HOW WE START
Send the two column-header lists, the proposed matching key and what you need compared. We confirm a permitted sample, acceptance checks, handling and retention, receiving route, and delivery date before accepting work or payment.
WHAT THIS DOES NOT INCLUDE
No live-system logins, automated downloads, fuzzy matching, Excel/VBA, PDF extraction, live imports, bookkeeping or background service. The report checks agreed comparison rules; it does not certify the underlying business data.
PROOF OF WORK
The sample is synthetic, not a client case study: 9 left records and 7 right records produce 4 unique matched pairs and 8 unpaired records, with 2 field differences and 2 invalid values. No client savings or production experience is claimed.
AI-assisted workflow development; the comparison program itself runs without a third-party model API.
