URL Encoder - Decoder

I was working with some list data submission and needed to make use of the GUID of the custom list that I had created. The GUID generally reads like this:
%7B79674320%2DADEA%2D4AE6%2DAAD2%2D29D33BE5EA7C%7D

To have this in a format acceptable to SharePoint, I found a nice little utility that encodes and decodes this beautifully.
After decoding it looks like this:
{79674320-ADEA-4AE6-AAD2-29D33BE5EA7C}

Thanks to Eric, I assume he is the author, for this tweaky thing !!
