GS1 Parser

Overview

GS1 Parser is a C# library for parsing GS1-conformant barcode strings. It reads the Application Identifiers within a barcode - such as SSCC, EAN, GLN, dates, and serial numbers - and exposes them as structured segments that calling code can work with.

Key Features

• GS1 Barcode Parsing: Parses GS1-conformant barcode strings into structured data
• Application Identifier Extraction: Extracts AIs including SSCC, EAN, GLN, dates, and serials
• Structured Segments: Returns the parsed values as discrete, typed segments
• Library-First Design: A focused parsing library with no UI or service layer

Technical Stack

• Language: C#
• Platform: .NET
• Type: Reusable parsing library

Architecture

The project is a pure C# parsing library:

• Core Library: C# code that performs the GS1 parsing
• Parser Components: Logic for recognising Application Identifiers and splitting a barcode into segments
• Structured Output: Parsed segments returned to the consuming application

Challenges & Solutions

• GS1 Standard Complexity: Handled the various GS1 Application Identifiers and their formats
• Variable-Length Data: Parsed AIs with differing lengths and delimiters into clean segments
• Reusable Design: Kept the parser as a focused library that other code can call directly

Impact & Results

• Reusable Parsing: Provides a building block for handling GS1 barcodes in C# applications
• Structured Data: Turns raw barcode strings into usable, structured values
