Instead of looping with cells individually to obtain or establish a worth, obtain or establish the values in the whole range of cells in one line, making use of a variant including a two-dimensional variety to shop values as needed.


The adhering to code example reveals non-optimized code that loopholes with cells one by one to get as well as set the worths of cells A1: C10000. These cells don't contain formulas. Dim Information, Array as Variety Dim Irow as Long Dim Icol as Integer Dim My, Var as Dual Set Information, Range=Range("A1: C10000") navigate here For Irow=1 to 10000 For icol=1 to 3' Read the values from the Excel grid 30,000 times.

My, Var=My, Var * Myvar' Write the worths back right into the Excel grid 30,000 times. Information, Array(Irow, Icol)=My, Var End If Following Icol Next Irow The complying with code example shows optimized code that utilizes an array to get as well as establish the values of cells A1: C10000 all at the same time. These cells don't consist of solutions.


Information, Variety = Range("A1: C10000"). Value2 For Irow = 1 To 10000 For Icol = 1 To 3 My, Var = Information, Array(Irow, Icol) If My, Var > 0 After That' Change the worths in the array. My, Var=My, Var * Myvar Information, Variety(Irow, Icol) = My, Var End If Following Icol Next Irow' Create all the values back into the range at as soon as.


Value2 = Data, Array returns the formatted value of a cell. This is slow, can lose accuracy, and also can trigger errors when calling worksheet functions.
