office-text-extractor is a Node.js library that extracts text from MS Office (docx, pptx, xlsx) and PDF files, designed for developers who need reliable text extraction without spawning child processes or relying on file extensions. It uses mime type detection and leverages specialized libraries like pdf-parse, xlsx, and mammoth for efficient parsing. The library is particularly useful for applications that process documents programmatically, such as data extraction tools, document analysis systems, or content management platforms.
