JSON

Je ne vais pas aborder le débat du choix entre CSV, JSON et XML, ce dernier étant déjà largement présent sur le net.

Le seul truc à retenir c’est que le JSON et le XML permettent des résultats sur plusieurs là le CSV ne peut pas.

Il faut savoir que Powershell gère nativement le JSON.

Par exemple, avec un Get-ChildItem:

Get-ChildItem  C:\Temp\Test\  | ConvertTo-Json

On obtient:

Bref un bon gros pavé bien complet en JSON 😀

Et comment on l’exporte ? Comme ça !

Get-ChildItem  C:\Temp\Test\  | ConvertTo-Json | Out-File .\MyFile.json -Encoding utf8 -Force

Voila, c’est tout simple !
