Alternative to SendKeys Enter for activating cells in excel with vba - excel

Question

I'm pasting some dates from a csv file into excel using a macro, and using a find/replace to alter the format into one excel can recognise, from 2019_10_22_08_43_23 to 22/10/2019 08:43:23, for example. Excel won't recognise this text as a date until you manually select the cell and press enter, and therefore won't display the dates on a graph correctly until this has been done. My current solution is using
For Each c In cycleRange.Cells
c.Select
SendKeys "{F2}", True
SendKeys "{ENTER}", True
Next
to manually press enter in each cell but this takes quite a long time. I have tried using TextToColumns but this isn't working. If I manually select the cell range, and navigate the data menu to click TextToColumn myself it corrects the cell format, but doing this through a macro doesn't do anything.
cycleRange.Select
Selection.TextToColumns Destination:=cycleRange, DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=False, _
Semicolon:=False, Comma:=False, Space:=False, Other:=False, FieldInfo _
:=Array(1, 1), TrailingMinusNumbers:=True
What's the fastest method to replace looping through each cell and using Sendkeys to activate them?

Answer 1

You want to convert each cell to number. Here is the code:
Dim cellValue As Double
For Each c In cycleRange.Cells
If IsNumeric(c.Text) Then
cellValue = c.Value
c.Clear
c.NumberFormat = "0.00"
c = Val(c.Text)
' c = c.Text * 1
' c = CDbl(c.Text)
Else
MsgBox ("Not a number (" & c.Address & ")")
End If
Next

Answer 2

It would be easier to combine the string conversion and cell formatting into one VBA operation
Something like this
Sub Demo()
Dim rng As Range
Dim cl As Range
Dim dat() As String
Set rng = [A1:A10] ' update to suit your needs
For Each cl In rng
If cl.Value2 Like "####_##_##_##_##_##" Then
dat = Split(cl.Value2, "_")
cl = DateSerial(dat(0), dat(1), dat(2)) + TimeSerial(dat(3), dat(4), dat(5))
cl.NumberFormat = "yy/mm/dd hh:mm:ss" ' update to suit your required format
End If
Next
End Sub

You can simulate to enter a cell and push enter by replacing a specific number by itself i.e. you replace 1 by 1. As such, the format changes. Doing this for 0, 1, then 2 up to 9 will cover all your cells, whatever figure is in the cell.
Here a macro:
Sub Repl1by1()
Cells.Replace What:="0", Replacement:="0", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="1", Replacement:="1", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="2", Replacement:="2", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="3", Replacement:="3", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="4", Replacement:="4", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="5", Replacement:="5", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="6", Replacement:="6", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="7", Replacement:="7", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="8", Replacement:="8", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
Cells.Replace What:="9", Replacement:="9", LookAt:=xlPart, SearchOrder _ :=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False
End Sub
