In our company we use a google spreadsheet which contains the prices of all our products. This prices are available in USD & Euros.
Now, the problem is that everyday one guy has to look for the Euro exchange of the day, and then change it on a cell, so I was wondering if we could call a webservice to retrieve the currency exchange of the day and automatically update the cell without having a guy doing that, cause to be honest, is like Homer Simpson drinking bird, there is no sense doing that job,
