Excel VBA Loop? - vba

Question

I am new to creating VBA macros. I recorded the macro below, but I need this done for 18 other worksheets in the workbook. I do not know how to create a loop. Can it be done from this recorded macro? Sorry for the long code. Again this code is used on 18 other worksheets and am unsure how to create a loop.
Sheets("C3 CONW INW OPIS_CMA").Select
Range("G1").Select
ActiveCell.FormulaR1C1 = "PSTRIK"
Range("A1").Select
ActiveCell.FormulaR1C1 = "PRECID"
Range("A2").Select
ActiveCell.FormulaR1C1 = "P"
Range("A2").Select
Selection.AutoFill Destination:=Range("A2:A26"), Type:=xlFillDefault
Range("A2:A26").Select
Range("C1").Select
ActiveCell.FormulaR1C1 = "PEXCH"
Range("C2").Select
ActiveCell.FormulaR1C1 = "7"
Range("C2").Select
Selection.AutoFill Destination:=Range("C2:C26"), Type:=xlFillDefault
Range("C2:C26").Select
Columns("O:O").Select
Selection.Delete Shift:=xlToLeft
Columns("N:N").Select
Selection.Delete Shift:=xlToLeft
Columns("E:E").Select
Selection.Delete Shift:=xlToLeft
Columns("J:J").Select
Selection.Delete Shift:=xlToLeft
Columns("D:D").Select
Selection.Delete Shift:=xlToLeft
Columns("E:E").Select
Selection.Cut
Columns("G:G").Select
Selection.Insert Shift:=xlToRight
Columns("I:I").Select
Selection.Cut
Columns("K:K").Select
Selection.Insert Shift:=xlToRight
Range("I1").Select
ActiveCell.FormulaR1C1 = "PQTY"
Range("G1").Select
ActiveCell.FormulaR1C1 = "PCTYM"
Range("D1").Select
ActiveCell.FormulaR1C1 = "PFC"
Range("B1").Select
ActiveCell.FormulaR1C1 = "PACCT"
Range("J1").Select
ActiveCell.FormulaR1C1 = "PPRTCP"
Range("E1").Select
ActiveCell.FormulaR1C1 = "PSUBTY"
Range("H1").Select
ActiveCell.FormulaR1C1 = "PSBUS"
Range("H2").Select
ActiveCell.FormulaR1C1 = "0"
Selection.AutoFill Destination:=Range("H2:H23"), Type:=xlFillDefault
Range("H2:H23").Select
Columns("I:I").Select
Range("I240").Activate
Selection.Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
Range("I1").Select
ActiveCell.FormulaR1C1 = "PBS"
Range("I2").Select
ActiveCell.FormulaR1C1 = "1"
Selection.AutoFill Destination:=Range("I2:I23"), Type:=xlFillDefault
Range("I2:I23").Select
Again sorry for the format of the code.

Answer 1

I cleaned up your code a bit, and put it into a sub which takes a worksheet as its argument. I then made another sub which loops through all the worksheets of the workbook the code resides in, and makes the changes specified.
Option Explicit
Sub test()
Dim ws As Worksheet
For Each ws In ThisWorkbook.Worksheets
Call fix_stuff_in_the_sheet(ws)
Next ws
End Sub
Sub fix_stuff_in_the_sheet(ws As Worksheet)
ws.Range("G1").FormulaR1C1 = "PSTRIK"
ws.Range("A1").FormulaR1C1 = "PRECID"
ws.Range("A2").FormulaR1C1 = "P"
ws.Range("A2").AutoFill Destination:=Range("A2:A26"), Type:=xlFillDefault
ws.Range("A2:A26").FormulaR1C1 = "PEXCH"
ws.Range("C2").FormulaR1C1 = "7"
ws.Range("C2").AutoFill Destination:=Range("C2:C26"), Type:=xlFillDefault
ws.Columns("N:O").Delete Shift:=xlToLeft
ws.Columns("E:E").Delete Shift:=xlToLeft
ws.Columns("J:J").Delete Shift:=xlToLeft
ws.Columns("D:D").Delete Shift:=xlToLeft
ws.Columns("E:E").Cut
ws.Columns("G:G").Insert Shift:=xlToRight
ws.Columns("I:I").Cut
ws.Columns("K:K").Insert Shift:=xlToRight
ws.Range("I1").FormulaR1C1 = "PQTY"
ws.Range("G1").FormulaR1C1 = "PCTYM"
ws.Range("D1").FormulaR1C1 = "PFC"
ws.Range("B1").FormulaR1C1 = "PACCT"
ws.Range("J1").FormulaR1C1 = "PPRTCP"
ws.Range("E1").FormulaR1C1 = "PSUBTY"
ws.Range("H1").FormulaR1C1 = "PSBUS"
ws.Range("H2").FormulaR1C1 = "0"
ws.Range("H2").AutoFill Destination:=Range("H2:H23"), Type:=xlFillDefault
ws.Range("I240").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
ws.Range("I1").FormulaR1C1 = "PBS"
ws.Range("I2").FormulaR1C1 = "1"
ws.Range("I2").AutoFill Destination:=Range("I2:I23"), Type:=xlFillDefault
End Sub
If you don't want the code to be performed on all the sheets in your workbook, you need to figure out a way for the first function to only be called with the sheets you want as an argument.
There is still some superfluous code in the subs I post here, e.g. you first autofill range A2:A26 with the letter P, but then later overwrites that with PEXCH. I'll leave it to you to weed out this though.
