# json-parser
A cli tool for lexical and syntactical analysis. It parses json files.
## [PyPI package](https://pypi.org/project/json-parser-cli/)
---
## Features

- Parser --> Builds python objects fro tokens.
- CLI Interface --> Validating json files from cli.

How compiler works
1. **Lexer.py** --> Convert text into tokens.
2. **Parser** --> Convert tokens to data using recursive descent parsing.
### Json features supported
- Objects, Arrays.
