ClosedXML System.Exception: Syntax error

Question

I am using ClosedXML to calculate values in excel sheet from user provided inputs and i am getting error on the cell containing following formula

IF(C2=1,VLOOKUP(D7,A15:D28,4),(IF(C2=2,VLOOKUP(D7,A33:D46,4),VLOOKUP(D7,F15:I28,4))))

On line:

lblResult.Text = worksheet.Cell("D8").Value;

Can you help me finding what's going wrong here?

Thanks in advance

Answer 1

ClosedXML doesn't support the VLOOKUP function.

See the documentation for a list of supported functions.

Answer 2

You can use worksheet.Cell("D8").CachedValue It will show you the value which, according to the calculation result, is in the cell
