How Text Extraction Works
There are two main types of text extraction:
1. Basic Parsing
Used for files like DOCX or HTML, where the text is already digitally encoded and just needs to be extracted using file parsers.
2. OCR (Optical Character Recognition)
Used for scanned documents and images. OCR software converts visual data into machine-readable text.

Best Practices for Accurate Text Extraction
1. Use high-resolution images for OCR—ideally 300 DPI or higher.
2. Clean the data using pre-processing techniques (e.g., denoise, grayscale).
3. Use the right tool for the job—don’t use OCR on digital PDFs.
4. Test and validate extracted data for accuracy and formatting.
5. Secure your documents during processing, especially for sensitive information.
