Regex to validate JSON

Question

I am looking for a Regex that allows me to validate json.

I am very new to Regex\'s and i know enough that parsing with Regex is bad but can it be used to validate?

Answer 1

For "strings and numbers", I think that the partial regular expression for numbers:

-?(?:0|[1-9]\d*)(?:\.\d+)(?:[eE][+-]\d+)?

should be instead:

-?(?:0|[1-9]\d*)(?:\.\d+)?(?:[eE][+\-]?\d+)?

since the decimal part of the number is optional, and also it is probably safer to escape the - symbol in [+-] since it has a special meaning between brackets
