If you lock your question for editing, someone may get angry and delete it alltogether.
Anyway, it is rude to lock it, so please stop doing so.

Based on this article - http://en.wikipedia.org/wiki/Intel_HEX[^] - it seems fairly easy to do this directly. The format is straightforward, so you don't really need any 3rd party library to do this.

As Nish said, the Intel HEX format is pretty simple.

Here's the information I found in my notes from back when I had to write a parser for HEX files:

Intel HEX record format:
Leader - 1 char (":")
count - 2 chars (number of 2 character pairs in the data section)
address - 4 chars (16-bit address where the data should be placed in memory)
EOF Flag - 2 chars (00 = normal record, 01 = last record in the file)
data - 0-512(?) chars
checksum - 2 chars (sum of data bytes + checksum + 1 = 0 mod 256)

NOTE: The checksum uses the actual data bytes, not the characters that represent them.

I think HEX files may allow other address sizes, so you may have to change the address field accordingly.
