About

CSV Repair Kit is a small workshop for a format that looks simple and fails loudly: comma separated values.

The tools exist because the same five accidents keep showing up in support queues — Excel locale delimiters, ANSI vs UTF-8, unclosed quotes, identifiers stored as numbers, and jagged rows from unquoted commas. None of those problems require a server. They require a careful parser and a preview.

What we will not do

• Ask for an account to download a repaired file
• Upload the CSV to inspect it
• Pretend scientific notation can restore digits Excel already rounded away

CSV Repair Kit is a static website. There is no application server behind the tools, no database, and no account system. JavaScript in your browser reads the file you select, diagnoses it, and can download a new copy. If you disconnect the network after the page has loaded, the tools still run.

Who it is for

Operators, analysts, and developers who receive CSV exports from Excel, CRMs, ERPs, or locale-specific finance systems and need to make them importable without sending customer data to a third-party converter.
