Direct Answer

It's a one liner actually. No need to use .Autofill Range("M3:M" & LastRow).Formula = "=G3&"",""&L3". This is a prose walkthrough, ranked #155th of 303 by community upvote score, from 2014.


The Problem (Q-score 3, ranked #155th of 303 in the Excel VBA archive)

The scenario as originally posted in 2014

So I’m working on a project and I’m trying to get my VBA code to draw down the formula that’s in cell M3 all the way down to the end of the data set. I’m using column L as my base to determine what the last cell with data in it is. My formula is a concatenate of two cells with a text comma in-between them. So in excel my formula is =G3&”,”&L3

I want excel to draw down this formula so in cell M4 it would be =G4&”,”&L4
Cell M5 would be =G5&”,”&L5 and so on.

My code looks like: 

Range("$M$3").Formula = Range("G3") & (",") & Range("L3")

Dim Lastrow As Long

Application.ScreenUpdating = False

Lastrow = Range("L" & Rows.Count).End(xlUp).Row
Range("M4").FormulaR1C1 = Range("G4") & (",") & Range("L4")
Range("M4").AutoFill Destination:=Range("M4:M" & Lastrow)
ActiveSheet.AutoFilterMode = False
Application.ScreenUpdating = True

My output is simply pulling down the text values from cell M3 all the way down to the end of the data set. I’ve searched around for several hours trying to look for a fix, but can’t seem to find one that is trying to accomplish what I’m going for.

What changed between 2014 and 2026

The answer is 12 years old. The Excel VBA object model has been stable across Office 2013, 2016, 2019, 2021, 365, and 2024/2026 LTSC, so the pattern still compiles. Changes that might affect you: 64-bit API declarations (use PtrSafe), blocked macros in downloaded files (Mark-of-the-Web), and the shift toward Office Scripts for web-first workflows.

Published 2014, which is 12 year(s) before today’s Office 2026 build. The Excel VBA object model has had no breaking changes in that window. Three things to re-test: (1) blocked macros on downloaded files (Mark-of-the-Web), (2) 64-bit API declarations (PtrSafe, LongPtr), (3) any shift toward Office Scripts for web scenarios.
