Greetings,

We receive the following error when we use the Import-XLXS module to try to combine 2 excel files in PowerShell 5.

    PS C:\windows\system32> $L = Import-XLSX C:\Users\Public\KBs\SecurityUpdates.xlsx
    Import-XLSX : Failed to open 'C:\Users\Public\KBs\SecurityUpdates.xlsx':
    Cannot find type [OfficeOpenXml.ExcelPackage]: verify that the assembly containing this type is 
    loaded.
    At line:1 char:6
    + $L = Import-XLSX C:\Users\Public\KBs\SecurityUpdates.xlsx

   + CategoryInfo          : NotSpecified: (  [Write-Error], WriteErrorException
   + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Import-XLSX  

I look forward to hearing back from you soon concerning this issue.

Hi John!

A few questions:

• How did you install PSExcel? Install-Module PSExcel? Download the zip from GitHub and extract somewhere? If the latter, you'll need to unblock the zip (or the files in it, particularly the dll in /lib)
• Where is the module installed? Network shares won't be an option in most cases, given the dll
• How did you import the module? Guessing this isn't the case, but you can't selectively use Import-XLSX.ps1, the module itself needs to load

Cheers!

Good news, we got the module working; however, we are still having the following issue. When we import the xlsx one sheet has embedded URLs and the other is for a join-object key. when we do a "join-object" and export-xlsx, why doesn't it keep the URLs?

I appreciate the help.
