This project provides a Node.js library for parsing SDF (Structure Data File) files, commonly used in cheminformatics to store chemical structures and associated data. It converts SDF files into arrays of JavaScript objects, allowing users to filter, include/exclude specific fields, and apply custom modifiers to the parsed data. The library is designed for cheminformaticians, chemists, and developers working with chemical databases or computational chemistry applications who need to process and analyze SDF files programmatically.
