Get cell formatting - excel

Question

Is there a function to get the activecell formatting? e.g. background color, font, font color, cell border, font size etc.
I want to update the format of an entire worksheet based on a formatted cell before action (i.e. the format I want to change) by another formatted cell (i.e. the format I want to apply).
Sub Rep_all_format()
Dim fmt_bef As CellFormat
Dim fmt_aft As CellFormat
Dim rngReplace As Boolean
Dim msg As String
Dim Sh As Worksheet
Dim Rg As Range
Dim ppos1 As Range
Dim ppos2 As Range
Dim Find As String
Dim Remplace As String
Set ppos1 = Application.InputBox(Prompt:="Select the cell format you wanna change", Title:="Remplace", Default:=ActiveCell.Address, Type:=8)
Set ppos2 = Application.InputBox(Prompt:="Select the cell format you wanna apply", Title:="Select", Type:=8)
Find = ppos1.FormatConditions 'this is theorical I do not know the function
Remplace = ppos2.FormatConditions 'this is theorical I do not know the function
Application.ScreenUpdating = False
Set fmt_bef = Application.FindFormat
Set fmt_aft = Application.ReplaceFormat
For Each Sh In ThisWorkbook.Worksheets
Set Rg = Sh.UsedRange
With fmt_bef
.Clear
.FormatConditions = Find
End With
With fmt_aft
.Clear
.FormatConditions = Remplace
End With
Rg.Replace What:="", Replacement:="", _
SearchFormat:=True, ReplaceFormat:=True
Next
fmt_bef.Clear
fmt_aft.Clear
Application.ScreenUpdating = True
MsgBox ("The desired format has been applied through all the workbook")
End Sub

Answer 1

Assuming, from the code that you have provided, that your cell has been formatted using Conditional Formatting, you need to access is the Range.DisplayFormat property.
Note that I showed only some of the formatting options for a cell. There is documentation online for other formatting options (eg other borders, numberformat, etc) but this should get you started.
For example:
Option Explicit
Sub foo()
Dim R As Range, C As Range
Dim fc As FormatCondition
Set R = Range(Cells(1, 1), Cells(5, 1))
For Each C In R
With C.DisplayFormat
Debug.Print .Interior.Color
Debug.Print .Font.Name
Debug.Print .Font.Color
Debug.Print .Borders(xlEdgeLeft).LineStyle ' etc
Debug.Print .Font.Size
End With
Stop
Next C
End Sub
If the cell has been formatted manually, or directly using code, then just access the various properties directly, not using the DisplayFormat property eg:
For Each C In R
With C
Debug.Print .Interior.Color
Debug.Print .Font.Name
Debug.Print .Font.Color
Debug.Print .Borders(xlEdgeLeft).LineStyle ' etc
Debug.Print .Font.Size
End With
Stop
Next C

What you are looking for are the Range.Interior and Range.Font properties etc.
