Currently, it is a 1024-byte file beginning with "# GRUB Environment
Block\n".  Entries are written as "NAME=VALUE\n".  The file is
fixed-size, and free space up to the end of the file is filled with '#'
characters.

However, the format is not documented, and so if you write any code
outside GRUB to edit these files it is subject to breaking with future
versions of GRUB.  Use the grub-editenv utility instead.

If that's exactly as written, then the signature is incorrect ("block"
instead of "Block").
