How to validate .odg files in Python

Python 
def is_odg(file_path: str) -> bool:
    """Check if file is a valid ODG by magic bytes."""
    signature = bytes([0x50, 0x4B])
    with open(file_path, "rb") as f:
        return f.read(2) == signature

How to validate .odg files in Node.js

Node.js 
function isODG(buffer: Buffer): boolean {
  const signature = Buffer.from([0x50, 0x4B]);
  return buffer.subarray(0, 2).equals(signature);
}

How to validate .odg files in Go

Go 
func IsODG(data []byte) bool {
    signature := []byte{0x50, 0x4B}
    if len(data) < 2 {
        return false
    }
    return bytes.Equal(data[:2], signature)
}

Frequently Asked Questions

What is a .odg file?

A .odg file is a ODG file.

What are the magic bytes for .odg files?

The magic bytes for ODG files are 50 4B at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .odg file?

To validate a .odg file, read the first bytes of the file and compare them against the known magic bytes (50 4B) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .odg files?

The primary MIME type for .odg files is application/vnd.oasis.opendocument.graphics.

Is it safe to open .odg files?

ODG (.odg) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
