# 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.
