How to save a JSON object to a file using Powershell? - json

Question

I have converted the following JSON file to powershell representation object.
{
"computer": [
{
"children": [
{
"children": [ {
"children": [ {
"path": "T:\Dropbox\kvaki.html",
"name": "kvaki",
"type": "url",
"url": "http://example.com"
} ],
"path": "T:\Dropbox\",
"name": "Njusha",
"type": "folder"
}, {
"path": "T:\Dropbox\Europa.html",
"name": "Europa",
"type": "url",
"url": "http://example.com"
}, {
"path": "T:\Dropbox\math.html",
"name": "math",
"type": "url",
"url": "http://example.com"
} ],
"path": "T:\Dropbox\",
"name": "Money",
"type": "folder"
}
],
"full_path_on_file_sys": "T:\Dropbox\"
}
]
}
After doing some computations with powershell representation I would like to save it to file as JSON.
But command $jsonRepresentation | ConvertTo-Json | Out-File "D:\dummy_path\file.json" saves it in this way
{
"computer": [
{
"children": " ",
"full_path_on_file_sys": "T:\Dropbox\"
}
]
}
Question: how to achieve correct saving of complex powershell JSON representation?

Answer 1

-depth argument for ConvertTo-Json solves the issue.
$jsonRepresentation | ConvertTo-Json -depth 100 | Out-File "D:\dummy_path\file.json"

Answer 2

Just pipe it to Set-Content, or Out-File:
Get-Process powershell |
ConvertTo-Json |
Set-Content json.txt

Answer 3

If you want to both view the output and save it to file, you can pipe the tee command.
Get-Process powershell | ConvertTo-Json | Tee-Object json.txt

Answer 4

$json.properties.metadata | ConvertTo-Json -Compress

Answer 5

if you are stuck with PowerShell Version 2, the JSON module of Joel Bennett from the 'PowerShell Code Repository' might help.

1) The below command can be used to convert a json to CSV
Example:
Get-Content package.json | Out-String | ConvertFrom-Json | Select parameter1, parameter2, parameter3 | ConvertTo-Csv -NoTypeInformation | Format-Table >> C:\JenkinsWorkspace\Result.csv
Get-Content: This is like "cat" command in linux which will get all data of file "package.json" and converts from Json (Using ConvertFrom-Json function) extracting the details of only required parameters and then converting them into CSV using "ConvertTo-Csv" function without any unwanted Type Headers and formatting them into Table.
2) The above result can also be formatted into proper csv to view it as Excel format without any duplicates and also having Text-To-Column conversion using below command:
Import-Csv "C:\Result.csv" -delimiter "," | Sort-Object _from -Unique | Export-csv "C:\FINAL_REPORT_$date.csv"
