powershell - Create Hashtable from JSON

Question

I want to get a JSON representation of a Hashtable such as this:

@{Path="C:emp"; Filter="*.js"}

ConvertTo-Json results in:

{
    "Path":  "C:\temp",
    "Filter":  "*.js"
}

However, if you convert that JSON string back with ConvertFrom-Json you don't get a HashTable but a PSCustomObject.

So how can one reliably serialize the above Hashmap?

Answer 1

$json = @{Path="C:emp"; Filter="*.js"} | ConvertTo-Json

$hashtable = @{}

(ConvertFrom-Json $json).psobject.properties | Foreach { $hashtable[$_.Name] = $_.Value }

Adapted from PSCustomObject to Hashtable
