.BIN file for ROM IC using proteus
A ".bin" file would clearly be a binary one, while you seem to be creating a text file containing something else, perhaps a printable hex dump.

Depending on what your source material is, you may be able to have the a tool specific to that flow translate to a binary output, for example with a gcc-style toolchain you can use objcopy for this.

Or you can find various "hex editor" tools which will let you edit in a format not unlike what you depict, but then save to a raw binary format.

If there is some organization to the file beyond flat binary, that would be something imposed by whatever is going to read your EPROM, not by the chip itself.  So it is not something which could be determined from information in your question.  Most commonly however, for systems which use single byte-wide storage devices there is not.
