LocaleLint CSV - Offline Game Localization QA

LocaleLint CSV is a small offline preflight tool for game developers and localization teams.

Open one HTML file, select a CSV, choose the key and source-language columns, and receive a downloadable issue report. Your localization file stays in the browser tab: there is no account, upload, telemetry, remote model, or network request.

Checks included

• UTF-8 encoding and common CSV delimiters

• malformed quotes and inconsistent row widths

• blank or duplicate headers and keys

• missing source or translated cells

• mismatched named and printf-style placeholders

• spreadsheet formula triggers and control characters

• bounded processing for predictable local behavior

Included

• LocaleLint CSV offline HTML application

• original safe and intentionally broken sample CSVs

• README, privacy disclosure, validation notes, and purchaser license

Important limitations

LocaleLint diagnoses; it does not translate or automatically repair text. It does not guarantee compatibility with every engine or custom placeholder syntax. Always work on a copy and test the resulting CSV in your own import pipeline.

AI-assisted development was used during implementation and documentation. The shipped runtime is deterministic and does not contain or contact a generative-AI model.
