Posted on 2011-03-07
Last Modified: 2012-06-21

I'd like to take my spreadsheet and extract every 19 records starting with record 1069 to create a random sample.  Should I create a macro or function to tell Excel to select every 19 records?

Please see attached worksheet.

The file you attached appears to be corrupted (and has 0 bytes)

Simply run a Macro to copy every 19th row

for i = 1 to 64000 step 19
Next i

Thanks very much for your reply.

I am not sure how to insert a macro. The code should also start at record 1069.

I'd really appreciate further assistance if possible.  Here's the sheet again.

Thanks so much!

Hi there,

Thanks so much for your quick reply.  The code does select the correct first record 1069 but it only selects 135 households. I need a sample size of 192.

Also, I have to run a simple coding on 8 more spreadsheets, so I need to be able to insert the macro. I can insert a Marco. I just need to be able to see the code in a separate worksheet.

Thanks so much! You're a star!

From 1069 to 3615 (the provided data) = 2546 records

Divide that by 19 and you have 35....  You could try with 18

The code is below... - to use press alt-f11 (to open VBA).  Use insert from the menu and insert a module..

In Module 1 paste the below.

To do it on different sheets change "Sheet1" and "Sheet2" to the sheets you want to do it on

To change sample size, change the "For i = 1069 To lastrow Step 19
" to step 18 or whatever
Sub tester()
lastrow = Sheets("Sheet1").Range("A64000").End(xlUp).Row
u = 1
Application.ScreenUpdating = False
For i = 1069 To lastrow Step 19
   Application.CutCopyMode = False
   u = u + 1
Next i
Application.ScreenUpdating = True

End Sub
