OK, it appears I have muddied the waters by only explaining what I think I need.
Given that my knowledge is poor at best i'll explain the whole problem to try and give it context which will hopefully help.
I have a file which contains a hex value of 01 at the beginning of each 'record' and a hex value of '03' at the end of each record.
Within each record there are several 'lines' of data that end with a hex value of '0D0A'
So the data would look like this (crlf signifies a carriage return/line feed)
If I look at it in a HEX viewer I see
The problem I have is that the application I need to put the file into has the following restrictions
- The ^A character(hex value of 01) needs to be replaced with a space(hex value 20). So, I want to replace hex 01 with hex 20
- The ^C character(hex value 03) needs to be replaced with a carriage return and two line feeds(hex values 0D 0A 0A). So, I want to replace hex 03 with hex 0D 0A 0A.
What I want to end up with is
Hopefully that makes what i'm aiming for a little clearer and apologies for not being accurate enough initially.
I must remove hex characters 0A and 0D from several fields within an MS Access Table. Since I don't think it can be done in Access, I am trying here.

Hi there!
I'm new in this and probably is a quite simple task but I still cannot manage to do it:

srec_ascii_hex - Ascii-Hex file format
DESCRIPTION
This format is also known as the Ascii-Space-Hex or Ascii-Hex-Space format. If you know who invented this format, please let me know. If
you have a better or more complete description, I'd like to know that, too.
The file starts with a start-of-text (STX or Control-B) character (0x02). Everything before the STX is ignored.
Each data byte is represented as 2 hexadecimal characters, followed by an "execution character". The default execution character is a
space, although many programs which write this format omit the space character immediately preceding end-of-line.
The address for data bytes is set by using a sequence of $Annnn, characters, where nnnn is the 4-character ascii representation of the
address. The comma is required. There is no need for an address record unless there are gaps. Implicitly, the file starts a address 0 if
no address is set before the first data byte.
The file ends with an end-of-text (ETX or Control-C) character (0x03). Everything following the ETX is ignored.
It is also possible to specify a running 16-bit checksum using a sequence of $Snnnn, characters, although this usually appears after the
ETX character and is thus often ignored.
Variant Forms
In addition to a space character, the execution character can also be percent (%) called "ascii-hex-percent" format, apostrophe (') or
comma (,) called "ascii-hex-comma" format. The file must use the same execution character throughout.
If the execution character is a comma, the address and checksum commands are terminated by a dot (.) rather than a comma (,).
Size Multiplier
In general, binary data will expand in sized by approximately 3.0 times when represented with this format.
EXAMPLE
Here is an example ascii-hex file. It contains the data "Hello, World[rq] to be loaded at address 0x1000.
^B $A1000,
48 65 6C 6C 6F 2C 20 57 6F 72 6C 64 0A ^C
