JSON support for new playlist format

[askotx]

Is it possible to add support for JSON format, I think it could be something like:

#if legacy then
    playlist_entry := playlist_entry_rom_path . "`n"
                    . playlist_title . "`n"
                    . core_path . "`n"
                    . "DETECT" . "`n"
                    . "DETECT" . "`n"
                    . playlist_name . ".lpl" . "`n"
#else
#this before start loop array
header := '"{`n"
 """version""":"""1.0""",`n"
 """items""": [`n"
playlist_file.Write(header)
#in array
playlist_entry :=  "{". "`n"
   . """path""": """. playlist_entry_rom_path . """,". "`n"
   . """label": """ . playlist_title . """,". "`n"
   . """core_path""": """. core_path . """,. "`n"
   . """core_name""": ""DETECT""",. "`n"
   . """crc32""": """DETECT""",. "`n"
   . """db_name""": """ . playlist_name .".lpl""". "`n"
   . "},". "`n"
 
playlist_file.Write(playlist_entry)

  #after array
  # remove last "," comma, I don't know the command
footer:=  "  ]`n"
  "}`n"
playlist_file.Write(footer)
#end if
