Excel to free chart with indicators.

#1
Greetings everyone,
1) I'm having OHLC data in excel. I want to make an graph with indicators like RSI, Bollinger bands... Any software or application to convert my data to chart with indicators?
2) Any idea of coverting one minute excel OHLC data to 5 min, 15 min, 30 min, 60 min data formula or code?

That would be much helpful. Thanks in advance.
