Copy Row A1 from Sheet 1 into Row A1 Sheet 2 - vba

Question

I basically just need to know how to copy a header from sheet one that goes from A1-O1 into sheet two, three, four, five and so on...they all have the same header. Sheet one is on the right and sheet two is left and increases to the left. I tried this which I found on some website but it says object required. The error is Runtime Error 424
mainworkBook.Sheets(“Sheet1”).Rows(1).EntireRow.Copy
mainworkBook.Sheets(“Sheet2”).Range(“A1”).Select
mainworkBook.Sheets(“Sheet2”).Paste

Answer 1

A small loop code.let me know if it works.
Sub COPYPASTeHEADER()
Dim K As Integer
For K = 2 To ActiveWorkbook.Sheets.Count
Sheets("All_Data").Range("A1:O1").COPY Sheets(K).Range("A1")
Next
End Sub

Answer 2

You can do something like this instead of using Select:
For Each Sheet In ThisWorkbook.Sheets
ThisWorkbook.Sheets("ALL_DATA").Rows(1).Copy Destination:=Worksheets(Sheet.Name).Range("A1")
Next
This will loop through each sheet in your workbook, take the range you provided (row 1 from Sheet1), and paste it to each sheet by referencing the Name property of each Sheet you are looping through.
The error may have been from the workbook variable, as that is the only thing that is unclear.
I would also recommend looking into this post: How to avoid using Select in Excel VBA macros as it is tremendously helpful in avoiding Select/Activate when possible, which is a common occurrence among those who learn VBA through recording Macros.
Let me know if it works for you.

Answer 3

This is an excellent place to use a loop. For each sheet in the workbook, paste the same header.
Sub forEachWs()
Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
Call pasteContents(ws)
Next
End Sub
Sub pasteContents(ws as Worksheet)
** Your code goes here
End Sub
EDIT: The ** section could be as such:
Sub pasteContents(ws as Worksheet)
ActiveWorkbook.Sheets(“Sheet1”).Rows(1).EntireRow.Copy
ActiveWorkbook.Sheets(ws).Range(“A1”).Select
ActiveWorkbook.Sheets(ws).Paste
End Sub
Or it could also be...
Sub pasteContents(ws as Worksheet)
ActiveWorkbook.Sheets("Sheet1").Rows(1).Copy Destination:=Worksheets(ws).Range("A1")
End Sub
