Numbrify is a small utility to convert number-like strings in objects and arrays into actual numbers. For example If you've ever parsed a csv file and gotten a bunch of numbers-as-strings in your object, this can help with converting those back to numbers. It will leave things that don't look like numbers alone.

NOTE: By default, Numbrify will do a deep traversal of properties/elements in the collection, however non primitive values that are not Arrays or Objects (e.g. dates) are copied by reference. So if you want a completely separate result and have lots of non primitive values you should deep clone your object first.

You can download a copy of the whole thing from the releases page. Or if you just want the built script there is here. Or if you are using npm, npm install numbrify.

Include the script into your page. Possibly like so <script src="dist/numbrify.js" charset="utf-8"></script>. The src attribute should point to wherever you downloaded the dist/numbrify.js file to.

Then call Numbrify(data, deepTraversal=true) with your collection. Here are some quick examples

var data;
var result;

// Numbrify an array
data = ["123", "456", "789.2342", "foo"];
result = Numbrify(data);
// Result should equal: [123, 456, 789.2342, "foo"];

data = [
  {"name": "foo", "age": "42"},
  {"name": "bar", "age": "32"},
  {"name": "baz", "age": "22"}
]

// Numbrify an array of objects
result = Numbrify(data)
// Result should equal:
// [
//   {"name": "foo", "age": 42},
//   {"name": "foo", "age": 32},
//   {"name": "foo", "age": 22}
// ]

// You can also do
result = data.map(Numbrify);

// If you want to only do a shallow traversal of your object, then pass in
// a second parameter set to false. e.g.
data = [
  {"name": "foo", "age": "42"},
  {"name": "bar", "age": "32"},
  {"name": "baz", "age": "22"}
]
result = Numbrify(data, false)

// Result should equal:
// [
//   {"name": "foo", "age": "42"},
//   {"name": "foo", "age": "32"},
//   {"name": "foo", "age": "22"}
// ]
// Note this has not done anything since the age property is in
// a nested object.

To build this locally, check out the repository, run npm install and then run npm build. There is also an npm watch task that rebuilds on changes to the src file.

The source is written in ES6/ES2015 primarily to take advantage of ES6 modules and the convenient UMD build provided by babel.
