VBA Excel looping with table autofill

Question

I have 2 values, where: A2 is a latitude and B2 is a longitude. Both changes on 0.25 step.

I would like to use these values to autofill the table using loop.

The idea is, that for every single value (e.g 49) I need another few values (for instance -2, -1.75, -1.5, -1.25, etc.) set in the same row, as per in the picture attached.

Firstly this loop (referring to one, latitude value):

Sub calc2()
    Dim i As Single
    With Worksheets("9")
    .UsedRange.clear
    .Range("a1").Value = "Input"
    .Range("f1").Value = "Output"
    For i = 40 To 55 Step 0.25
        Worksheets("1_GENERAL").Range("A2").Value = i
        With .Cells(Rows.Count, 1).End(xlUp)
        .Offset(1, 0).Value = i
        .Offset(1, 1).Value = Worksheets("4.MINUTES").Range("BL371").Value
        End With
    Next i
End With
End Sub

, which makes an autofill in 2 column (latitude value in 1st and output value in 2nd). Secondly I was trying to modify this loop in order to vertical autofill, which allow me to set values in rows (1st row a longitude value, 2nd row output value). Next steps should contain only an output values corresponding to relevant lon, lat value.

The loop looks like this:

Sub calc_full()
    Dim i As Single
    With Worksheets("9")
    .UsedRange.clear
    .Range("a1").Value = "Input"
    .Range("b1").Value = "Output"
    .Range("c1").Value = "Input"
    .Range("d1").Value = "Output"
    For i = 40 To 45 Step 0.25
    For k = -2 To 2 Step 0.25
        Worksheets("1_GENERAL").Range("A2").Value = i
        With .Cells(Rows.Count, 1).End(xlUp)
        .Offset(1, 0).Value = i
        .Offset(1, 1).Value = Worksheets("4.MINUTES").Range("BL371").Value
        End With
        With .Cells(Cols.Count, 1).End(xlUp)
        .Offset(2, 0).Value = k
        .Offset(2, 1).Value = Worksheets("4.MINUTES").Range("BL371").Value
        End With
    Next i
    Next k
End With
End Sub

However it doesn't work. I must have mix something. Basically my output value is located in different worksheet (4.MINUTES) and I would like to paste it in one place for different coordinates, making a table eventually (see an example in the attachment). Any ideas how to do this? I will be grateful a lot. Thank you in advance.

Answer 1

I was trying your code, but the problem is, that no error shown but code doesn't work.

Sub autofill_example()
Dim i As Long
Dim LAT As Double
Dim LON As Double
Dim Lastrow As Long
Dim Lastcolumn As Long
Dim Times As Integer

With Sheets("9")

    LAT = Sheets("1_GENERAL").Range("A2").Value
    LON = Sheets("1_GENERAL").Range("B2").Value

    Times = (55 - LAT) / 0.25

    For i = 1 To Times
        Lastrow = .Range("A" & Rows.Count).End(xlUp).Row

        LAT = LAT + 0.25

        .Range("A" & Lastrow + 1) = LAT

    Next i
        Debug.Print LAT

        Times = (LON + 7.75) / 0.25

        For i = 1 To Times
            Lastcolumn = .Cells(1, .Columns.Count).End(xlToLeft).Column

            LON = LON - 0.25

        .Cells(1, Lastcolumn + 1) = LON

    Next i

End With

End Sub

Could you advise about the With value? My LON and LAT values are on separate sheet.

Answer 2

@Mariusz Krukar import the values 49 & 25 as in the picture below and try:

Option Explicit

Sub test()

Dim i As Long
Dim LAT As Double
Dim LON As Double
Dim Lastrow As Long
Dim Lastcolumn As Long
Dim Times As Integer

With wsTest

    LAT = .Range("A2").Value
    LON = .Range("B1").Value

    Times = (55 - LAT) / 0.25

    For i = 1 To Times
        Lastrow = .Range("A" & Rows.Count).End(xlUp).Row

        LAT = LAT + 0.25

        .Range("A" & Lastrow + 1) = LAT

    Next i
     Debug.Print LAT

    Times = (LON + 7.75) / 0.25

    For i = 1 To Times
        Lastcolumn = .Cells(1, .Columns.Count).End(xlToLeft).Column

        LON = LON - 0.25

        .Cells(1, Lastcolumn + 1) = LON

    Next i

End With

End Sub

the result is like the picture:
