The MA file format is a legacy notebook format developed by Wolfram Research for early versions of the Mathematica computational software system. It served as the standard container for saving mathematical calculations, symbolic code, visualizations, and document annotations. While superseded by the NB format in version 3.0, these ASCII-based text files generally remain readable by modern Wolfram products for archival and compatibility purposes.

How to validate .ma files in Python

Python
def is_ma(file_path: str) -> bool:
    """Check if file is a valid MA by magic bytes."""
    signature = bytes([0x28, 0x2A, 0x2A])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .ma files in Node.js

Node.js
function isMA(buffer: Buffer): boolean {
  const signature = Buffer.from([0x28, 0x2A, 0x2A]);
  return buffer.subarray(0, 3).equals(signature);
}
Go
func IsMA(data []byte) bool {
    signature := []byte{0x28, 0x2A, 0x2A}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
}
