Helpful regular expressions (pcre) I often use

helpful_regular_expressions

(?<![\S"])([^"\s]+)(?![\S"])
    Find all strings not enclosed in quotes. Workx ok well. Often used to add quotes to JSON notation that doesn't have it yet. Currently doesn't detect brackets like [, [, }. That needs some fixing.

Not yet well working. Wanting to use it to wrap JSON structures in correct quotes.

Example:

{
    ID: "1325",
    number: "269",
    array: [{
        ID: "1325-20131155303"
    }]
}

Should be this:

{
    "ID": "1325",
    "number": "269",
    "array": [{
        "ID": "1325-20131155303"
    }]
}
