Select Excel row --> Create Hashtable from Entries - excel

Question

I have an Excel .xlsx-file which looks like this:
Now I'd like to create a PowerShell script, which can do the following:
Ask the User which row he wants to use (for example 4)
Create a hashtable with those entries
The hashtable should look like this:
Name Value
---- -----
Name Jane Doe
Age 67
Street Grace St. 19
Zipcode 12345
Date 03.03.2013
Does someone know how I can achieve this?
Plus: Is this actually achievable with a xlsx-File or do I need to use a CSV-file?

Answer 1

First, it is achievable if we convert the xls to csv:
$excelFilePath = "C:\Temp\abc.xlsx"
$Excel = New-Object -ComObject Excel.Application
$Excel.Visible = $false
$Excel.DisplayAlerts = $false
$Workbook = $excel.Workbooks.Open($excelFilePath)
$($Workbook.Worksheets | where {$_.Name -eq "Sheet1"}).SaveAs("C:\Temp\abcd.csv", 6)
$Excel.Quit()
I would suggest using an ID instead of row number:
$importedAbcd = Import-Csv -Path "C:\Temp\abcd.csv" -Delimiter ";"
[int]$answer = Read-Host "Select ID to work with"
$object = $importedAbcd | Where-Object {$_.ID -eq $answer}
You have the row now converting it to hash:
$hash = #{}
$object.psobject.properties | Foreach { $hash[$_.Name] = $_.Value }

Answer 2

A more intuitive way is to
read the excel file directly with the Import-Excel module
pipe it to Out-Gridview, select a single line
and populate the hashtable
$HashTable = [ordered]#{}
Import-Excel "x:\path\sample.xls" | Out-GridView -OutputMode Single -Title "Select one line" |
ForEach-Object {$_.psobject.properties | ForEach-Object {
$HashTable[$_.Name]=$_.Value
}
}
$HashTable
Sample output:
> $HashTable
Name Value
