PHP Practice Project #2

CSV → JSON Converter (PHP)

This project demonstrates file-upload handling, CSV parsing, JSON encoding, and file I/O in pure PHP — no frameworks, no dependencies.

---

Overview

The page lets a user:

1. Upload a .csv file.
2. Convert its contents into a structured JSON array.
3. Save the JSON to a local text file (output.txt).
4. Display the formatted JSON on screen in a scrollable textarea.

Everything runs in-browser with plain PHP.

Features

• Secure file upload (move_uploaded_file)
• Automatic folder creation (mkdir)
• CSV parsing with fgetcsv()
• Clean data handling (skips blank/mismatched rows)
• JSON conversion using json_encode(..., JSON_PRETTY_PRINT)
• File writing with file_put_contents()
• Human-readable display inside <textarea readonly>
