Working with json in powershell powershell tutorial

working with json in powershell: a comprehensive tutorial

json (javascript object notation) is a lightweight, human-readable data-interchange format. it's commonly used for transmitting data between a server and a web application, or storing configuration data. powershell provides powerful built-in cmdlets and features to easily work with json data, making it a breeze to read, write, and manipulate it. this tutorial will guide you through everything you need to know about handling json in powershell, complete with code examples.

**1. understanding json structure**

before diving into powershell code, it's crucial to understand the basic structure of json. json data consists of key-value pairs, similar to powershell hashtables. it supports the following data types:

* **strings:** enclosed in double quotes (e.g., `"hello"`)
* **numbers:** integers or floating-point numbers (e.g., `123`, `3.14`)
* **booleans:** `true` or `false` (lowercase)
* **null:** `null` (lowercase)
* **arrays:** ordered lists of values enclosed in square brackets (e.g., `[1, 2, 3]`)
* **objects:** unordered collections of key-value pairs enclosed in curly braces (e.g., `{"name": "john", "age": 30}`)

a json document typically consists of a single top-level object or array.

**2. importing json: `convertfrom-json`**

the `convertfrom-json` cmdlet is the primary tool for importing json data into powershell. it parses a json string and converts it into powershell objects (typically `pscustomobject` or arrays of `pscustomobject`).

**syntax:**

* **`-inputobject`:** specifies the json string to convert. this can be a literal string, the contents of a file, or the output of another command.
* **`-ashashtable`:** (optional) converts the json object into a powershell hashtable instead of a `pscustomobject`.

**examples:**

**b) from a file:**
