🔄 JSON Minifier – Compress JSON Data

🧩 Understanding JSON Minification
JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write. However, the whitespace and formatting that make JSON readable also increase its file size.
Minification is the process of removing all unnecessary characters from JSON data without changing its structure or validity:
- Whitespace - Spaces, tabs, and newlines are removed
- Indentation - All indentation is eliminated
- Line breaks - Multiple lines are combined into a single line
