Occasionally, you may have to update values in an Excel spreadsheet. PowerShell can access the Excel object model however this is quite slow. Here is an example that opens an Excel file, then writes information to A1 cell, and finally saves the changes.

Make sure you adjust the path to point to an existing Excel file.

$excel = New-Object -ComObject Excel.Application
# open Excel file
$workbook = $excel.Workbooks.Open("c:\test\excelfile.xlsx")
# uncomment next line to make Excel visible
#$excel.Visible = $true
$sheet = $workbook.ActiveSheet
$column = 1
$row = 1
# change content of Excel cell
$sheet.cells.Item($column,$row) = Get-Random
# save changes
