When you need to quickly extract sentences or paragraphs that meet specific length requirements from a large amount of text, manual filtering is both time-consuming and error-prone. This tool accurately calculates the character count of each text unit (each letter, number, punctuation mark, or CJK character counts as 1 character) and automatically filters the text based on your minimum and maximum length thresholds, keeping only the content that meets your criteria.
How is the length of an emoji calculated?
Each emoji is uniformly counted as 2 characters, which aligns with the string length calculation standards of most programming languages.
Why are the filtering results for my Chinese text not as expected? Please check if it contains full-width punctuation or special symbols, as these characters might be counted differently than half-width characters. We recommend testing the tool's accuracy with plain text first.
For batch processing, we recommend keeping each line under 500 characters, as excessively long text may impact browser performance. This tool does not store any user-inputted text; all calculations are performed locally on your device.
For SEO optimization scenarios, we recommend filtering for paragraphs between 50-60 characters to use as Meta Description candidates. Example: If you input "This is a test|Length filtering example|Text that needs to meet specific word count requirements" (separated by |) and set the range to 50-60 characters, it will accurately return the matching text segment.
