What Is Excerpt Generator?
An excerpt generator is a text processing tool that creates shortened versions of text by truncating it at word or sentence boundaries rather than cutting mid-word. Developers and content creators use it to create meta descriptions, article previews, and card descriptions, solving the specific problem of producing poorly formatted summaries when using simple truncation methods. For instance, when creating a meta description for a web page, it is crucial to have a well-formed summary that does not end abruptly mid-word.
This tool stands out from basic text truncation techniques due to its ability to intelligently find the nearest natural breakpoint before the length limit. It allows users to specify a maximum length, suffix, and boundary type, which can be set to word, sentence, or character limits. The boundary type determines how the text is truncated, with options to break at word boundaries, sentence boundaries, or a specified character limit.
The tool's flexibility in handling different boundary types makes it particularly useful for creating text previews that need to fit within specific character limits. By using this excerpt generator online, developers can create text excerpts that read naturally and are well-formed, which is essential when creating content previews. It provides features like customizable suffixes and maximum lengths, allowing users to fine-tune the output to suit their needs, making it a valuable asset for anyone looking to create high-quality text previews or truncate text at word boundaries effectively.

Technical Guide
The excerpt generator supports three truncation strategies: Word boundary truncation finds the last space character before the length limit using lastIndexOf(" "), ensuring the excerpt ends at a complete word. Sentence boundary truncation uses regex to find sentence-ending punctuation and selects the last complete sentence that fits within the limit. Character truncation simply slices at the exact character limit. In all modes, the configured suffix is appended when text was actually truncated. If the original text is shorter than the limit, it's returned unchanged without a suffix.
