You can always have a live chart in Tradingview. Not only for USD/INR but for every other pairs in the world. Heck you even have the choice of selecting the brokers or the data providers for each pairs you want to see.
In case you would like to have this forex rate automatically refreshed inside your Excel spreadsheet so that you can build your own linked spreadsheet calculations, you may consider the Deriscope addin.
