Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

The folder shown above contains a number of files, some of which are Excel workbooks.

Create a macro to loop over all of the files in the folder.  Your macro should:

  • Check for each file whether it is an Excel workbook (ie use the RIGHT function to check whether the right-most 3 or 4 characters of the file name are XLS or XLSX, depending on your Excel version)
  • Open up the workbook with the given path
  • Write your name into cell B2
  • Close the workbook back down, saving any changes

If you can't remember how to open and close workbooks - record a macro!

When you have got the macro to work, save it as Signing workbooks, then close it down.

If you want another challenge, given the files in the folder above, create a macro in a new workbook which:

  • Creates a new folder on your C drive with a name of your choice, if it doesn't already exist
  • Copies all of the TXT files shown above into this folder
  • Deletes the file called Po.txt
  • Renames Laa Laa.txt to Yellow teletubbie.txt

Save this workbook as Various file tasks, then close it down.
