Question

Is there any way to rename or/and delete corrupted ranged names, which include spaces, e.g. “ACVCutoff_4 1” in Excel file with help of powershell? I got stuck on this. Renaming or deleting names fails.

$Excel = New-Object -Com Excel.Application
$wbTo = $Excel.workbooks.open($path)
foreach($name in $wbTo.Names)
{
    $name.Name = $tt -replace '\s+', '_' # name is not affected
    $name.delete() # returns an error Exception calling "Delete" with "0" argument(s): "Exception from HRESULT: 0x800A03EC"
}

What I have tried:

1. Including Name manager add-in does not solve the issue.
2. “Check R1C1 Reference Style” (check the link) – how can it be achieved by writing a code?

Any other suggestions? I would appreciate your help

I am using powershell v2 and Excel 2007/2010.

That’s the file with broken names: XlsWithBrokenNames

SOLUTION BY Chris Neilsen for those who are also stuck on this:

#$wbTo - is workbook with corrupt names
$tempFilePath = $path + "temp.xlsm"
$goodFilePath = $path + "cleanFile.xls"
$wbTo.SaveAs($tempFilePath,52) #save as xlsm
$wbTemp = $Excel.workbooks.open($tempFilePath) # open target
# delete names here
$wbTemp.SaveAs($goodFilePath,56) #save as xls

Answer 1

All direct manipulation of the corrupt names i have tried has failed!

But, here’s a possible alternative:
SaveAs your workbook as a .xlsm You should get a dialog complaining about invalid names, with a option to rename and a Ok to All button. Once saved, close and reopen the file, Save As an .xls and you should be good to go
