CSV Repair & Deduper

CSV Repair & Deduper is a small browser tool for people who receive, export, or combine CSV files and need a careful cleanup pass before importing the data somewhere else. It is designed around a simple promise: inspect the file, make proposed changes visible, and let the person responsible for the data review the result before downloading it.

The product runs locally in the browser. The intended workflow does not upload the CSV to a remote processing service, which makes it a practical option for a contact export, order export, or other file that a team would rather keep on its own device. The product page also explains the privacy model and shows how a visitor can check the browser Network panel for unexpected requests. This is a useful distinction from web tools that require a file to be sent to a server.

The first part of the workflow is repair and inspection. The tool helps identify common structural problems such as delimiter mismatches, uneven row shapes, quoted fields, embedded line breaks, and encoding-related trouble. A malformed file can appear to be a duplicate problem when the parser has shifted columns or swallowed a row, so checking the structure first is important. The product is intended to make that inspection easier and more understandable rather than silently guessing that every irregular row should be changed.

The second part is duplicate review. Exact duplicates can be identified directly, while near-duplicates can be flagged when records differ in small ways such as capitalization, extra spaces, or a minor spelling variation. A near-match is not automatically the same person or order, so the tool presents proposed changes for review. It is not a claim that fuzzy matching can replace judgment. The person using the product remains responsible for deciding which records should be kept, merged, or left alone.

A short guided demo on the product page uses a contact-list example and an order-export example. The sample result card reports one exact duplicate proposed, one near-duplicate flagged, two unique rows kept, and zero automatic deletions. Those numbers are a demonstration of the review-first behavior, not customer results or a guarantee about a visitor’s own file. The page also includes a free guide collection covering broken CSV files, encoding, merging, blank rows, leading zeros, whitespace, schema checks, and other practical import problems.

CSV Repair & Deduper is a downloadable one-time product priced at $19, with no subscription. The purchase page uses a real checkout flow and provides the downloaded product after a successful payment. The offer is intentionally narrow: it is for local CSV repair, review, and deduplication. It is not a CRM migration service, a hosted data warehouse, a medical or financial system, or a promise to repair every possible proprietary export. Large files may be slower in a browser, and users should keep an original backup and inspect the exported result before importing it.

For a small business operator, analyst, freelancer, or ecommerce worker, the value is a repeatable checkpoint between receiving a file and trusting it downstream. Instead of opening a spreadsheet and immediately overwriting the source, the user can work from a copy, identify suspicious structure, review duplicate proposals, and export a cleaned result with more confidence. The product page describes the limits plainly so a buyer can decide whether the offline workflow matches the job.
