🧹 JSON Cleaner

A lightweight Node.js tool to parse, clean, and normalize messy JSON — especially helpful when dealing with stringified or deeply nested JSON from legacy systems or third-party APIs.

📁 Project Structure

json-cleaner/
├── rawdata.txt        # 🔸 Raw input with messy JSON
├── cleanJson.json     # ✅ Cleaned output (auto-generated)
└── main.js            # 🧠 Script with core logic

---

⚙️ How It Works

1. Reads raw JSON from rawdata.txt
2. Parses & cleans:
   • data.updated.updated — may be a stringified JSON array
   • Each invoice.attachment — possibly stringified JSON objects
3. Safely transforms these fields into real JSON structures
4. Outputs a clean, pretty-formatted JSON file → cleanJson.json

🔐 Fault Tolerant

If a field like attachment fails to parse, the script logs a warning and keeps going:

⚠️ Could not parse attachment for invoice: INV-12345

🚀 Quick Start

1. Clone the Repository

git clone https://github.com/yourusername/json-cleaner.git
cd json-cleaner

2. Add Your Raw JSON

Drop your raw/messy JSON into a file named:

rawdata.txt

3. Run the Cleaner

Make sure Node.js is installed, then run:

node main.js

If successful, you'll see:

✅ Clean JSON written to cleanJson.json

---

✅ Requirements

• Node.js v12+
• No external libraries — uses native fs and path modules only

---

🧪 Example Use Cases

• Cleaning double-encoded JSON from outdated APIs
• Normalizing inconsistent data before importing into a database
• Quickly validating and formatting malformed JSON for automation or manual QA

✅ Notes:

• I cleaned up repetition, reduced emoji clutter, and added visual hierarchy for easy reading.
• You can replace "Your Name" and links with real content.
• Want a badge section (e.g., node version, license)? I can add that too.
