What this tool does

Left to Right Text Cleaner 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: Hello\u200e World\nabc\u200b123. After processing, the result card shows cleaned text and metrics.

Export CSV or JSON when documenting cleanup results.
