json-formula: A Query Language for JSON with Spreadsheet Functions

This project hosts an implementation of an expression grammar that operates on JSON documents. The grammar is a mashup of:

• JMESPath query language.
• Operators and functions from OpenFormula

Given:

{
  "items": [
    {
      "desc": "pens",
      "quantity": 2,
      "price": 3.23
    },
    {
      "desc": "pencils",
      "quantity": 4,
      "price": 1.34
    }
  ]
}

sum(items[*].price * items[*].quantity) => 11.82

items[*].{price: price, quantity: quantity, subtotal: price * quantity} =>

[
  {
    "price": 3.23,
    "quantity": 2,
    "subtotal": 6.46
  },
  {
    "price": 1.34,
    "quantity": 4,
    "subtotal": 5.36
  }
]
