How to Insert Excel Formula using PowerShell?

Question

The formula =LEFT(AB4,FIND(\" \",AB5)-1 works perfectly in Excel, but seems to be causing errors in PowerShell where I get this error:

Exception from HRE         


        

Answer 1

Quotes within a quoted string need to be doubled-up.

$worksheet.range("AH5:AH$rows").formula = "=LEFT(AB4,FIND("" "",AB5)-1)"
'you can also get rid of the inside quotes with the CHAR function
$worksheet.range("AH5:AH$rows").formula = "=LEFT(AB4, FIND(CHAR(32), AB5)-1)"

ASCII character 32 is a space. I've also added a bracket to make a legal formula.
