About the Online Chinese Character Extractor
The online Chinese character extractor quickly extracts all Chinese characters from mixed text, automatically filtering out non-Chinese content such as English, numbers, symbols, and URLs. It is suitable for handling a variety of inputs such as article snippets, chat logs, log text, and crawler data.
The tool supports a "deduplicate or not" option: when enabled, you get a list of unique characters, ideal for organizing data before new-character counting and character-frequency analysis; when disabled, the original duplicate characters are kept, useful for corpus restoration or observing repetition.
Core Features
- Batch character extraction: Filter out all Chinese characters from a large body of text with one click.
- Deduplication mode toggle: Supports keeping duplicates or extracting a unique set of characters.
- Copy and export results: Copy results directly, or download TXT or Excel files.

## Frequently Asked Questions
1. Can the tool extract traditional characters?
Yes. The tool extracts based on the Chinese character range, and common simplified and traditional characters can both be recognized.
2. Why did I get no results?
Usually the input contains no Chinese characters, or the text is empty. Please check the input and try again.
3. What is the difference between enabling and disabling deduplication?
With deduplication enabled, each character is kept only once; with deduplication disabled, every occurrence of each character in the text is kept.
4. Can the extraction results be downloaded?
Yes. After extraction, you can download them as TXT or Excel, making it easy to further organize and archive them.
