PowerShell 7.3 - implementing JSON Deserialization of Large Arrays Using `ConvertFrom-Json`
I'm sure I'm missing something obvious here, but Quick question that's been bugging me - I'm working on a PowerShell script that processes a large JSON file containing an array of objects, and I'm working with a performance scenario when using `ConvertFrom-Json`... When I try to deserialize a file that has over 10,000 records, the command takes a important amount of time to complete, and occasionally it throws an behavior: `ConvertFrom-Json : want to convert 'System.String' to the type 'System.Management.Automation.PSCustomObject'`. I've tried breaking down the JSON into smaller chunks and deserializing them one at a time, but that only partially mitigates the scenario. Here’s a snippet of the code I'm using: ```powershell $jsonFilePath = 'C:\path\to\largeData.json' $jsonData = Get-Content -Path $jsonFilePath -Raw $objects = $jsonData | ConvertFrom-Json ``` When I execute this, I also notice that the memory usage spikes significantly, which leads me to suspect that the entire content is being loaded into memory at once. I tried adding `-AsArray` to the `ConvertFrom-Json` call, thinking it might help, but it resulted in the same behavior. Has anyone else faced this scenario, and is there a way to optimize JSON deserialization for large arrays in PowerShell? Any best practices or alternative approaches would be greatly appreciated. For context: I'm using Powershell on macOS. What am I doing wrong? I'm working on a service that needs to handle this. I've been using Powershell for about a year now. Any ideas what could be causing this?
