What this tool does

Japanese Text Counter checks the input for language-specific characters, Unicode issues, formatting risks, and cleanup opportunities.

The tool applies Unicode-aware regular expressions, optional cleanup rules, script counting, width analysis, hidden-character detection, and before/after reporting.

Quality score is based on hidden characters, mixed formatting, script-specific issues, and how much cleanup was required.

Example

Example input: \u4eca\u65e5\u306f\u65e5\u672c\u8a9e\u306e\u6587\u5b57\u6570\u3092\u6570\u3048\u307e\u3059\u3002\u30ab\u30bf\u30ab\u30ca\u3068\u3072\u3089\u304c\u306a\u3001\u6f22\u5b57\u3092\u5206\u6790\u3057\u307e\u3059\u3002. After processing, the result card shows cleaned text and metrics.

Use cases

  • Clean copied text from PDFs, websites, spreadsheets, and AI tools.
  • Prepare multilingual text for publishing, SEO, translation, and localization.

Tips for better output

  • Use strict cleanup for data, CSV, JSON, and code-like text.
  • Use report-only mode when you need to inspect text before changing it.
  • Export CSV or JSON when documenting cleanup results.

Processing details

Processing runs locally in the browser. The tool does not send your text to a server.

Automatic script detection is based on Unicode ranges and may not identify every language variety or orthographic convention.
