You've asked this at least 3 times.

If you want to extract the data within the lines you're going to need to parse them individually.

These formats have been used commonly since the late 1970's so there should be documentation and examples, and frankly they are not that complicated.​

Dont waste time with this. use hex2bin.exe

I think the point was to dump .HEX or .BIN on the folder of a USB Flash Drive, and that's then loaded via the STM32
