How to convert tick data to OHLC?

I got a question from someone regarding how to convert market data ticks to OHLC (Open High Low Close). It went a little like this:


Hi Bryan are you able to process csv tick data files to OHLC 1 min bars easily? I am looking for a tool or app to do this. Let me know if you have any ideas.


Depending on the programming language, there some  choices of course. Even some people in my Facebook group came up with some great ideas.
