# Mac – macro to split the contents of an Excel spreadsheet into separate spreadsheets

macrosmicrosoft excelsplitter

I know there are similar questions out there but I don't think they are quite the same.

First name -- Surname -- Host Trust -- Contact details -- etc -- etc

It is a large spreadsheet. I have to send an email every week to host trusts to inform them of who will be working with them and it is a nightmare dividing this up manually.

Is it possible to create a macro which will split this spreadsheet into several spreadsheets using the the data from the Host Trust column as the title of each spreadsheet?

Not knowing what version of Excel you are using, I can not guarantee this will work. It does what you ask (I tested it), buy filtering on column C, creates a tab for each unique record, then copies those rows to the new sheet. You will need to modify the code toward the top so it matches the range of your data.

BEFORE YOU DO ANYTHING; make a copy of your file as a backup.

If you are familiar with VBA, Alt + F11 will open the VBA window, you can copy this code directly. Once saved, it will appear in the macro list for you to run.

To give credit where credit is due, I found this at Excel Forum.

'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.
