merrymonk has asked for the wisdom of the Perl Monks concerning the following question:

I wanted to be able to format numbers in Excel spreadsheet with formats stored in a hash.
Using the ‘traditional’ method of recording macros in Excel I have done this for:
1. Numbers only
2. Numbers with negative numbers begin shown in Red
3. Costs with the Pound, Dollar and Euro and Euro sign.
Perl for this, which produces examples in a spreadsheet, is given below.
It would be good to be able to show negative costs in red. However, I could not find a way of doing this in Excel 2007 and therefore it may not be possible.
I have tried modifying the ‘ordinary’ costs formats but failed!
Does anyone know what the format should be?
