A fastest way to write values to Excel cells?

Howdy Spicy and Powershelling friends,

I'm (still ... gosh) working with PS and Excel to write down reports of folder analysis with robocopy.

It's all working, but now I want to speed up the process.

I've found a really good way to create the initial values (I mean, the first time the sheet is created and filled with robocopy values), using a .net array then throw it in the actual sheet :

$count=$values.Countif($values.Count-eq$null){$count=1$rowtogo=2}else{$rowtogo=$values.Count+1}$arraynet=New-Object'object[,]'$count,3$i=0foreach($entryin$values){try{$arraynet[$i,0]=$entry.Root}catch{"!!!"}$arraynet[$i,1]=$entry.Directory$arraynet[$i,2]=$([string]$entry.size).replace(",",".")-as[double]$i++}$range=$sheetname.cells.range("A2:C$($rowtogo)")$range.value2=$arraynet
