Sample input:

JSONSyntaxHighlight("{\"key\": \"value\"}")

Sample output:

{ "key" : "value" } ... but with colors

Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

While([
    json = JSONFormatElements( json );
    stringColor = RGB ( 200 ; 100 ; 100 );
    symbolColor = RGB ( 25 ; 90 ; 250 );
    colonColor = RGB ( 50; 150; 255 );

    ln = PatternCount( json ; "\"");
    i = 1;
    result = ""
]; i <= ln ;[

   first = Position ( json ; "\""; 1 ; i );

   second = Position ( json ; "\"" ; 1 ; i + 1 ) + 1 ;

   chars = Substitute ( Middle ( json ; second ; Position ( json ; "\"" ; 1 ; i + 2 ) - second ); 
      ["{" ; TextColor ( "{" ; symbolColor )];
      ["}" ; TextColor ( "}" ; symbolColor )];
      [":" ; TextColor ( ":" ; colonColor )]
   );

   phrase = TextColor ( Middle ( json ; first ; second - first ) ; stringColor ) & chars;

   result = result & phrase;

   i = i + 2

]; 

   Substitute ( Left ( json ; Position ( json ; "\""; 1 ; 1 ) - 1 ); 
      ["{" ; TextColor ( "{" ; symbolColor )];
      ["}" ; TextColor ( "}" ; symbolColor )];
      [":" ; TextColor ( ":" ; colonColor )]
   ) & result & 

   Right ( json ; Length ( json ) - Position ( json ; "\"" ; 1 ; ln ) )

)

This will take a JSON object and format it with color. I've attempted to make the function simple so that you can modify it to include any colors you want to use without diving fully into the function.
