Here's my Hex to ASCII .
You need only do the word to nibble conversion.

;****************************** HEX to ASCII **********************************

; Converts a HEX nibble, passed in "W", returned in "W".
;******************************************************************************

HEX2ACSII MOVWF ADJ_CHAR ; Save the HEX nibble.
  MOVLW '0'  ; Form the character "0".
  ADDWF ADJ_CHAR,F ; Convert a 0-9 HEX nibble to a Character.
  MOVLW '9'  ; Form the character "9".
  SUBWF ADJ_CHAR,W ; Test the new character.
  BTFSC STATUS,Z ; Is the new character a Nine?
  GOTO H2A_Exit ; Yes, Return sucessful.
  BTFSS STATUS,C ; No, Does the new character need further adjust?
  GOTO H2A_Exit ; No, Return sucessful.
  MOVLW 0x07  ; Yes, Form the Alpha character adjust.
  ADDWF ADJ_CHAR,W ; Convert a A-F HEX nibble to a Character.
  RETURN  ; Done.
;
H2A_Exit MOVF ADJ_CHAR,W ; Fetch the adjusted (HEX) character.
  RETURN  ; Done.
