cmd-to-json v1.0.1

cmd-to-json

A simple CLI utility for creating JSONs from command line.

Installation

npm i -g cmd-to-json

Usage

Create JSON from command line by specifying properties and their values:

to-json name="John Doe" age=32 married=true

gives this output (formatted for better readability):

{
  "name": "John Doe",
  "age": 32,
  "married": true
}

Main use-case of the tool is calling APIs with curl from command line:

to-json userId=123 title="Post title" body="Post body..." | curl -X POST -d @- -H "Content-type: application/json" https://jsonplaceholder.typicode.com/posts

Nested objects

Nested structures can be created by using dots in property names:

to-json version=1 person.name="John" person.age=32

will yield:

{
  "version": 1,
  "person": {
    "name": "John",
    "age": 32
  }
}

Arrays are not yet supported.

Explicit formats

Numbers and booleans are recognized and formatted automatically. You may force a specific format like this:

to-json houseNumber:string=134 age:number=35

which will yield

{"houseNumber":"134","age":35}

Appending :string suppresses automatic formatting. :number and :boolean can be used for input validation (e.g. to-json age:number="foo" will throw an error).

Limitations

Currently there's no way to escape the special characters in property names (:, =, +, ., single _).
