Usage

After installing from PyPI:

python -m check_json_format <json_file_path>

When running from a source checkout:

python check_json_format.py <json_file_path>

What it does

• Format validation: Checks if the file is valid JSON (syntax, brackets, commas, etc.).
• Duplicate keys: Reports duplicate keys at the same object level (when detectable).
• File handling: Handles missing files, permission errors, and encoding issues.
• Exit behavior: Prints SUCCESS: Valid JSON format and optional duplicate-key messages; exits with non-zero on validation failure.

Output

• Valid JSON: SUCCESS: Valid JSON format and [SUCCESS] No duplicate keys found.
• Invalid JSON: Error details from the JSON parser.
• File issues: Clear messages for file not found, permission denied, or encoding errors.
