JSON format


There are just a few rules that you need to remember:

Else we come up with some error,

  • Objects are encapsulated within opening and closing brackets { }
  • An empty object can be represented by { }
  • Arrays are encapsulated within opening and closing square brackets [ ]
  • An empty array can be represented by [ ]
  • A member is represented by a key-value pair
  • The key of a member should be contained in double quotes. (JavaScript does not require this. JavaScript and some parsers will tolerate single-quotes)
  • Each member should have a unique key within an object structure
  • The value of a member must be contained in double quotes if it’s a string (JavaScript and some parsers will tolerates single-quotes)
  • Boolean values are represented using the true or false literals in lower case
  • Number values are represented using double-precision floating-point format. Scientific notation is supported
  • Numbers should not have leading zeroes
  • “Offensive”” characters in a string need to be escaped using the backslash character
  • Null values are represented by the null literal in lower case
  • Other object types, such as dates, are not properly supported and should be converted to strings. It becomes the responsability of the parser/client to manage this.
  • Each member of an object or each array value must be followed by a comma if it’s not the last one
  • The common extension for json files is ‘.json’
  • The mime type for json files is ‘application/json’

Cheers
