Game Localization Preflight Auditor

Catch localization data problems before they reach your release build.

Game Localization Preflight Auditor is a read-only static QA tool for game localization files.

It scans CSV and PO localization data for known structural, encoding, placeholder, locale, plural, Unicode, and completeness risks — without executing, importing, or modifying the audited project.

What it checks

• Malformed CSV and PO files
• Invalid UTF-8 and BOM-related issues
• Duplicate and missing localization keys
• Missing or empty translations
• Duplicate locale columns
• Invalid or suspicious locale identifiers
• %s, %d, %f, {0}, {name} and related placeholder mismatches
• PO plural and context consistency
• Missing plural translations
• Suspicious invisible Unicode control characters
• Unusually large localization entries
• Text-expansion risk heuristics
• Identical source/translation heuristics
• Spreadsheet formula-like cell risks
• Optional possibly-unused-key checks

Evidence-first reports

Generate both JSON and Markdown reports containing findings, severity, confidence, file/entry information, evidence, recommended actions, coverage information, and known limitations.

Designed to avoid false confidence

An incomplete scan is not reported as a clean scan.

Unsupported files, parser failures, permission problems, resource-budget limits, and other unknown conditions are surfaced explicitly instead of being silently treated as PASS.

Read-only by design

• Does not execute the audited project's code
• Does not import the audited project
• Does not open the audited project as a Godot project
• Does not modify localization files
• Does not write reports inside the audited target
