PowerShell output random numbers to csv. CSV full of empty lines-CodePudding

Actually 2 part question here. The code below outputs nothing but 1000 blank lines to the csv. I'm just trying to output a random range of numbers to a csv and I actually need to follow up with 4 more columns of randomly generated numbers like this first attempt so the second part of this is after getting this first issue resolved how would I direct the next ranges to the other columns?

Get-Random -Count 998 -InputObject (8000..8999) | Export-Csv -Path SingleColumn.csv -NoTypeInformation

CodePudding user response：

Export-Csv same as ConvertTo-Csv is not designed to deal with array of values:

0..10 | ConvertTo-Csv # Outputs `AutomationNull.Value`

Both cmdlets require you to feed them objects:

0..10 | ForEach-Object { [pscustomobject]@{ foo = $_ } } | ConvertTo-Csv

You can create new objects easily with PSCustomObject.

As for the second question, you can dynamically create a dataset by tweaking this code:

$columnsCount = 5
$numberOfrows = 998
$min = 8000; $max = 9000

1..$numberOfrows | ForEach-Object {
    $out = [ordered]@{}
    foreach($column in 1..$columnsCount) {
        $out["Column $column"] = Get-Random -Minimum $min -Maximum $max
    }
    [pscustomobject] $out
} | Export-Csv path/to/csv.csv -NoTypeInformation

Few lines of Csv output would look something like this:

"Column 1","Column 2","Column 3","Column 4","Column 5"
"8314","8937","8789","8946","8267"
"8902","8500","8107","8006","8287"
"8655","8204","8552","8681","8863"
"8643","8375","8891","8476","8475"
"8338","8243","8175","8568","8917"
"8747","8629","8054","8505","8351"
"8102","8859","8564","8018","8817"
"8810","8154","8845","8074","8436"
"8626","8731","8070","8156","8459"
....
