Crate deformat 

De-format: extract plain text from HTML, PDF, and other document formats.

NER engines, LLM pipelines, and search indexers need plain text. deformat sits upstream: it takes formatted documents and returns clean text. No I/O – it operates on &str and &[u8] inputs.

Quick start

use deformat::{extract, Format};

// Auto-detect format and extract text
let result = extract("<p>Hello <b>world</b>!</p>");
assert_eq!(result.text, "Hello world!");
assert_eq!(result.format, Format::Html);

// Plain text passes through unchanged
let result = extract("Just plain text.");
assert_eq!(result.text, "Just plain text.");
assert_eq!(result.format, Format::PlainText);

Feature flags

All features are opt-in. The default build has one dependency: memchr (SIMD-accelerated byte scanning).
