Zbzb is right. But deriscope is 20 usd flat!
Cant beat this.
And founder Ioannis (unrelated) is cool and a trainned quant.
Sorry Zbzb, I should have explained further
Yes, Deriscope is limited in the sense that it is relying on Yahoo and IEX for the free stuff. So restricted to 7-days for 1 minute intraday data.
But a on-off $20. That's it. No one can beat that.
Alphavantage is subscription-based, but I found that Yahoo Finance is good enough personally.
I think www.worldtradingdata.com would be best for the OP as no need to use excel as it is an API. It says 500 real time quotes per request on the main page.
