Not accepting '{' as first character

[walidam]

Unfortunately, my json is without keys:
{{a:1, b:2},{c:3, d:4}}
JsonMachin not accept that saying:

In Parser.php line 368:
                                            
  Unexpected symbol '{' At position 18139.

Is there a solution for that please?

Same thing with [{a:1, b:2},{c:3, d:4}]

Your JSON is wrongly encoded. Object cannot miss keys. As for the second example, object keys must be double quoted.
