Quick Start

Converting between full-width and half-width characters is a common need in text processing, especially in programming, typesetting, and data cleaning. HeronTool provides convenient online tools that require no installation.

  1. Open the HeronTool website and find the "Full to Half Width" tool.
  2. Paste or type the text you need to convert into the input box.
  3. Click the "Convert" button, and the tool will instantly convert all full-width characters (e.g., ,。!") to half-width ones (e.g., , .!" ).
  4. Copy the converted result, or click "Download" to save it as a text file.

If you need the reverse operation (half-width to full-width), HeronTool provides a corresponding tool with identical steps.

Practical Use Cases

  • Programming: Accidental full-width symbols in code can cause compile errors; use this tool to quickly fix them.
  • Document Formatting: Standardize punctuation in mixed Chinese-English text for more professional documents.
  • Data Cleaning: Full-width digits and letters often cause matching issues in Excel or databases; converting ensures data consistency.
