Formating Dates on a previously created document

Hi Helene

Thank you for your question

Having explored your question I'm afraid I can find not way to carry out the above task using basic Excel Tools.

It is possible to do this by writing a macro which will look at each cell in the worksheet and if it finds a date will format it in the manner required. This is however beyond the scope of the forum

As a result a colleague of mine will contact you to discuss other possibilities

Regards

Stephen
