The Challenge of Parsing CAS Files

Building your own CAS parser presents several challenges:

1. Complex PDF Extraction: CAS files are secured PDFs with varying layouts

2. Format Variations: Each issuer (CDSL, NSDL, CAMS, KFintech) uses different formats

3. Regular Changes: Formats change periodically, requiring constant updates

4. Data Normalization: Raw extracted data needs significant processing to be useful
