Create a new workbook for all unique values

Important message to visitors of this page

Ron de Bruin decided to remove all Windows Excel content from his website for personal reasons. If you want to know why, head over to rondebruin.nl.

Luckily, Ron was kind enough to allow me to publish all of his Excel content here.

Most of these pages are slightly outdated and may contain links that don 't work. Please inform me if you find such an error and I'll try to fix it.

Other examples and Example workbook

For more examples and a example workbook with the code below go to :
Copy records with the same value in a column to a new sheet or workbook

The range for the code example below looks like this
Column A : Header in A1 = Country, A2:A? = Country names
Column B : Header in B1 = Name, B2:B? = Names
Column C : Header in C1 = Gender, C2:C? = F or M
Column D : Header in D1 = Birthday, D2:D? = Dates

This example will create a new folder for you with a new workbook for every unique value in the first column of the range.The workbooks will be saved with the Unique value in the name into the newly created folder. It will also add a worksheet to your workbook named "RDBLogSheet" with hyperlinks to the newly created workbooks so it is easy to open the workbooks. Every time you run the macro it delete this worksheet first so the information is up to date.

Check if the information in these lines in the macro is correct before you run the macro

1: Set filter range on ActiveSheet: A1 is the top left cell of your filter range and the header of the first column, D is the last column in the filter range. You can also add the sheet name to the code like this :
Worksheets("Sheet1").Range("A1:D" & LastRow(Worksheets("Sheet1")))
No need that the sheet is active then when you run the macro when you use this.
Set My_Range = Range("A1:D" & LastRow(ActiveSheet))

2: Set the Filter field:This example filter on the first column in the range (change the field if needed). In this case the range starts in A so Field 1 is column A, 2 = column B, ......
FieldNum = 1

3:Important:This macro call a function named LastRow
You find this function below the macro, copy this function together with the macro in a standard module
