+# Excel Macros
+
+Excel macros are a poor solution for most problems,
+however some simple formatting motions are a good fit.
+
+This document is a step-by-step process for implementing such a macro,
+assuming a fresh Excel install.
+
+## 1. Enable Developer Tools
+
+```menu
+File > Options > Customize Ribbon
+```
+
+On the right side, under `Main Tabs`, check `Developer`.
+
+## 2. Create `PERSONAL.XLSB`
+
+```menu
+Developer > Code > Record Macro
+```
+
+Set `Store macro in:` to `Personal Macro Workbook`
+and click `OK`, then `Stop Recording`.
+
+## 3.
+
+```menu
+Developer > Visual Basic
+```
+
+In the pop-up window, navigate to and double-click
+"VBAProject (PERSONAL.XLSB)/Modules/Module1"
+
+Erase the empty macro created in step 2
+and add desired macros here.
+My favorite is provided below.
+
+```vb
+Sub FillDownEmptyCells()
+    Dim rng As Range
+    Dim cell As Range
+
+    ' Check if a range is selected
+    If Selection Is Nothing Then
+        Exit Sub
+    End If
+
+    ' Set the selected range
+    Set rng = Selection
+
+    For Each cell In rng
+        If IsEmpty(cell.Value) Then
+            ' Copy cell above to empty cell
+            cell.Value = cell.Offset(-1, 0).Value
+        End If
+    Next cell
+
+End Sub
+```
+
+Use `Ctrl+S` or the save icon to save the edits
+then close the Visual Basic window.
